Derek my father passed away a couple of days ago from cancer he was a big fan of yours and also love watching vise grip garage he always say you catch phrases and stuff that you always say on your videos So thank you for entertaining my father over the years when he was a subscriber/watcher

You might be the first person in the history of the planet that bought a reman ECM that actually worked out of the box.

I just loved my GM headliner. On a cold day, it would drop down on my head and keep it warm. What an innovation.😂

I’m 42 and my first car at 16 was my grandfathers 1970 Cadillac Sedan Deville. My grandparents were poor children of immigrants in the early 1900s in Oklahoma and eventually moved to California when it didn’t suck in the 1930s. Lol! They loved Cadillac and then finally in the 80s when they could finally afford some used ones they got a 68, 69 and a 70 over the years and finally felt like they had made the big time. I remember driving around with them in the 90s as a kid thinking I was the coolest kid going to church or when they would pick me and my cousins up after school to help on the farm. When I was 16 my grandfather sold me his 1970 Sedan Deville for $1000! It was almost mint in 1998. Most kids were driving old 80s imports or 90s if they were lucky. I was rolling in this 1970 pimp ride! I wish I never got rid of it.

Best line in the WHOLE video at 17:53...."If I remover this again its gona be with an axe and a fire exstingguisher".......I was ROLLN !!!

Died when you slapped that electrical tape over that check engine light after all that 🤣

Electronics nerd here... Derek working the DIP28 sockets - that's pure gold! 😀

Hey, those black spider legged things are what the original IC's (integrated circuits) looked like. In my early days (mid to Late 1960's) I worked for Texas Instruments, where we built the huge electronic machines that were designed to Test those EC's. I didn't have the smarts to design them, I was just one of the assembly Techs that assembled those monsters from the frame up, including doing all the soldering work on the circuit and ran all the wiring harnesses throughout the machine. It was the best time of my young college days. I loved it.

I worked as a driveability technician at a gm dealership back in the late 80s until mid 2000s. Cadillac was the worst to work on. Gm had software updates for every car to address multiple running issues, so you had to order a new prom, then install it when it came in. Once gm switched to EEPROM systems, it was way easier. We simply downloaded new updates thru the tech1 terminal and uodate using the OBD1 port. Also, code 12 is used as a self check for the ecm, it always states no tach signal as the engine is off during code check. Codes can be erased by simply disconnecting the battery for at least one minute. Also, after it cycles thru 3 read cycles, you you can erase the codes by pressing off and hi. Once it reads 00, codes are cleared

I was a Cadillac tech during the '80s. I don't miss working on those rolling nightmares. To clear codes, pull the ECM BATT fuse for 15 seconds. Don't worry about those dents in the tire sidewalls, it's just where the cord plys are joined.

Really surprised you haven’t installed An exhaust port to your overhead doors so you can get the exhaust outside of your fabulous building. A guy needs to use his lungs a while longer and it also make it safer for your little people. Really enjoy the channel, and how much you care about and work to make your family a part of what you do every day. Keep on keeping on blessings to you and yours

Hi Derek I'm soon to be a fellowern Tennesseer. Spent 25 years in Olds and Caddy stores shops. That wire to the trans is needed for 4-6-8 opperation. The solenoids that push the rocker arms over failed alot. Most people did disconect the trans. Overheating a problem also fan clutch failure and rad airflow must be clear. Sometimes took a few atemps to burp the system.. As for the wirecaps look for caddy emblems a simple swap or a feller might glue them. Your hardest part is the bumper fillers first to be eatan by the sun . I'll be a watchen.😇

I also do vintage computer repair, and watching you yank those chips then try to cram em back in was terrifying and hilarious. :) I recommend a chip puller, a pin straightener, and some DeOxit D5 if you ever have to do that again.

Your reaction when it fired was pure and real! We can tell that you had absolutely zero expectations that this turd was ever going to fire or run! Excellent.

Late 80's I was a GM technician. Roger Garner Chevy. Cadillac wiring specialist. Drivability and engine rebuild. Those were Good challenges!!! Thank you for sharing this beast of a car. I owned an 8,6,4. Loved it !!!

We used to own one of these 4-6-8s. The GM dealer mechanic cut a transmission sensor wire to disable it. He said it was the best way. Our 368 was carboned up, and it shook a bit running on 6, so that's why we cut the wire, but ours actually worked, and saved some gas before that. Ours turned out to be a rare 2 door Fleetwood Brougham. Gold, white and chrome!

I perused the comments but didn't see anyone mention it. The bleep boop box you pulled out had a reman sticker on it already. That means someone had already changed it once. Also I noticed how easily you pulled the one EPROM. It made me wonder if it wasn't loose and that's why it ran earlier and then quit. Just my observations... Nice to see the old girl running even if I'm not a Cadillac guy.

I still like the fact you’re keeping it simple no over budget builds like the other channels, thanks for keeping it real.

Dad was a Cadillac mechanic from 1955 to 1989. It's something to see all these details again.

Absolute respect for keeping the original solution and trying to get all the features of it working!

From 1990 to 2000, I was the Union Representative at Don Rosen Cadillac, just outside of Philly. In 2000 they sold the Franchise back to GM, as part of GM Project 2000. They had 4 Cadillac Master Craftsman who worked there and they were the Best Cadillac Flat Rate Technicians, I ever saw during my 47 years in the Automotive Mechanic Profession. Love the channel, it warms my old retired Mechanic heart.

Owned the top of the line version of this car at the end of the 90's. Original, low miles, one elderly owner car. Very deluxe, Kelsey Hayes real wire wheels. Put a boatload of work and money into it. Nothing would ever stay fixed. The insulation on the huge bundle of wires in the door hinge reminded me of dried silly putty, fell off in inch long chunks. These cars were still in the wrecker yards then and I had multiple computers, TBIs, etc for "just in case". So, so many problems. It just never ended. I loved it so, I gave it the best I had, and eventually, it just broke my heart. If you don't hate Caddys yet, this car will fix that for you. Run away, save yourself.

been watching for years. Derek, keep this as original as possible!! its a 2 year option car thats SO close to being 100%! this thing would be rolling working history if you keep it all original working! dont give up. cant wait to see more of this thing on the channel. best car u own!!

This episode really brought back memories. I was a young Service Director of one of the largest Cadillac stores in the Metro Detroit area in the late 70's to mid 80's. Thanks for your shout out of respect for the techs in that era. That car caused a lot of lost sales to Lincoln. Unfortunately, it was replaced by the HT4100 the following year. Many more years of heartburn for Cadillac. Love your channel and stuff on TV. Wish you and your beautiful family continued success. One last thing, I learned very quickly how to manage and turn around an upset customer or a overworked and upset technician trying to get their 8-6-4 back on the road.

My grandfather was a Cadillac master and worked for Sewell Village for 27 years. He retired in '89 and unfortunately, we lost him in 2001. He'd love this series and would probably be cussing that design. :D

I realize this vehicle could easily make a fella frustrated to no end, so just watching the never ending clever humor just truly makes my day. Thank you for producing all of the hands down best you tube channel.

My uncle bought this exact car. Same year, color, hub caps and engine. I recall it being rather gutless, but the engagement of the 8-6-4 system felt like a trans shift, so not bad at all. They really didn't have much trouble with it at all.

Please. This is 1 of those cars that has to live and be restored. Go on VGG, give us a full resto❤

I worked as an electronic tech in the 80's and I was cringing when Derek first started to put the PROMs in the reman PCM. He got it done though without bending up the pins. Nice job! As always a very entertaining video.

All the old school Cadillac guys were cheering when you finally said "off and warmer". 😊

This is awesome. I love seeing old stuff get fixed instead of swapped for something else.

These old Cadillacs are so cool, Back in the day anyone that drove one was a B.T.O. " Big time operator". You get that old car dialed in, you're going to fall in love with it.

VGG showed up today in an MSN article on the 10 Best Car Restoration Shows on TV. They had GREAT things to say about you.

I love the fact you switch from a full build of a pick up, to a problem child caddy and still show on your other channel the real life of owning and building your infrastructure. I look forward to every episode.

I really am glad for this part 2! If ever a car needed saving this caddy is it. We often get perplexed at technology. Thanks for not giving up!

The flashback edit on the exhaust was really, just, perfect

The best VGG are when derek is struggling and confused. Need more like this 👍👍👍

LMAO, when messing with the gas tank Derek says "how do I..." and for whatever reason here I am thinking 'liiiiive without you' and what do you know our guy follows up saying the same thing. I damn near died laughing

Yes, Mr. Derrick, sir. I remember the index cards. I remember going to the local library walking up to the card catalog and following the dewey decimal system in order to find the book I wanted.

Man I loved your tv show. Father and I got sick with COVID a year ago and we binge watched your show. Your channel finally showed up on my fyp, and I started watching! Love your funny humor; keep it up!

How cool is this Derek took on the challenge to fix one of the most problematic engines and rose to the occasion occasion Hats off to Vise Grip Garage.

My husband worked on those at the Cadillac dealership years ago. He said they were a pain in the bottom. 😅 He is explaining everything to me as we watch. He now teaches college in Ontario

I love that your whole family is involved. Wonderful. Perhaps the most family oriented car channel in all the world. Love you people.

This man is a hero. He suffers on these horrid repairs for our entertainment and knowlege. Salute*

My Dad had one of these brand new. Drove it two days and brought it back to the dealer and said he never wanted to see it ever again. By the way he had the exact same color like yours. They gave him another one without that crazy engine.

I am loving this restoration let’s go and try to get this gal completely running!!! You are the first person on UKposts that’s tried this in depth. I don’t know how you have found all of this information because I have run into a lot of dead ends!!! Love it Derek

This car is why I am subbed to you. You are inspiring me to keep working on my '79 4 door version. Thank you again!

DEREK! Hold down OFF, then keep holding it and hold down WARMER!! Same for clearing codes hold down OFF, then hold down HI. This brings back a lot of memories, most of them bad 😀

Your pure joy and excitement that it actually runs was shared with the engineers, assembly line workers, dealer make ready folks and lastly, the unfortunate owners of that automobile. “Stay running…stay running, oh it’s running” !! Joking aside I tip my hat to you staying determined to get it running with its original fuel injection. Such a fun video thank you !

I have nothing but love, admiration and appreciation for your style, and the content of this video.

Hey Derek! I live in Burnsville MN... loved watching you back in the day... still love your videos, never miss one. My dad passed last Tuesday... he had no idea what UKposts was let alone who you are... but I enjoyed your videos through a tough time... he didn't give a crap... but I give a crap. Thanks!

My cousin Jimmy idolizes you! He talks like you, dresses like you, has all your merch, has a mullet....even has pictures of you in his bathroom! So I had to check out your channel. Good stuff, the wife and I watch it together, it's become our thing together. Keep up the great work!

Clearing Trouble Codes - During trouble code display: Simultaneously press and hold ‘OFF’ and ‘LO’ buttons When ’00’ is displayed: Release the ‘OFF’ and ‘LO’ buttons To end diagnosis: Press the ‘AUTO’ button, or switch ignition OFF for 10 seconds

Derek, Really enjoy your channel with all the awesome content. Really impressed with your patience and knowledge displayed as you troubleshoot your way through so many different issues. Keep up the good work and many blessings to you and your family. Steve-Ohio

I had a factory limo 1981 10 passengers when we retired it car had 360k on the clock the 4V6/8 worked perfectly.

I graduate from H.S. in 1981. The Gas Saving 864 Caddy was designed. When gas was $1 a gallon and minimum wage was $3.35.

This car was by far my favorite build video😂😂😂😂😂hilarious!!!

Former tire guy here. That area on that rear tire is ok. Now, if it was bulged out, then a guy has something to worry about. That means separated steel belt in there.

Love that you are revisiting an old project!

The neighbor across the street from my grandmother was the guy who put that Cadillac book together every year, that was his job. Strange living in the Detroit Suburbs how you meet so many people with cool jobs. Love you guys brother! ❤

Derek I have to say that I have never seen a brake drum take off like that in all my years as a mechanic I’ve seen oxygen tanks blow through the wall, but never a drum rolling on the ground like that 🤣🤣🤣🤣🤣🤣🤣

Had a Cadillac 8-6-4 sedan .. white with red leather seats. Was a great ride up and down the east coast. Great at highway speed, but a pain at city driving, shifting back and forth through the active cylinder changes. Six cylinders was terrible. We finally put a toggle switch in to by pass the cylinder changes.

God bless you for going through all this to show us how this car runs. Love your videos!

Oh well, if you wanted to know about one of these, I was the guy. I worked as a tech in a Cadillac dealership at the time those came out. Truth that it didn't work well. You can't dump gas in a cylinder that doesn't fire. I actually have the book you are going through. It was fun working on those things!

Derek you went toe to toe with this caddy and you win by TKO outstanding Job and work and diagnostic!!!!!!!!! You Rock!!!!!!!!!!!!

Glad you finally got it going, enjoyed the video. Brought back memories of my dad's 4/6/8, 4 door gray Fleetwood , many road trips, he put 250k miles on it.

That Caddy was a mistake in 81and STILL is!! The diesel Oldsmobile was too!!REST IN PEACE!🪦

That was a one year only disaster for Cadillac! The dealer mechanics just hated to work on them because they never stayed fixed. The “fix” was to clip some wires so they only ran on 8 cylinders. Things got even worse the next year when the POS HT 4100 engines came out. These were followed up by the troublesome Northstar engines. These were dark days for the mighty Cadillac when they lost most of their long time loyal customers.

I did my first headliner 2 years ago and it was so much easier than I thought it would be. I kicked myself for all those years of having crappy headliners. You should include that in an episode. I got the material from Hobby Lobby. They've got the foam backed material just like the original headliners. All you need is a can of 3M headliner adhesive and the material. I took a drill and a wire wheel to get the old glue off the headliner board then I just sprayed it down and laid the new headliner on. It's not really that hard to take out the old headliner board so you can work on it.

Great video!! I had an 83 DeVille with a 4.1L and it did the exact same thing yours did, overheat and show low voltage code when driving. Even though it looked ok, had to replace belt between water pump and crank and tighten the heck out of it......

Saw the previous video on the Cadillac. My heart went out to you Derek. Glad to see this new video.

Derek, your patience is inspiring. Your bravery too. If I opened the hood and saw the hose factory that exploded under there, I'd a just closed it again and sent it on it's way. I sure appreciate being able to relax, learn a thing or two, and get encouraged by your videos. Thanks to you and your wonderful family for all you do!

Gotta say, fella was watching Cletus on his helicopter and got the notification that VG video was up. Had to say good bye to Cletus.

as a guy who rebuilds pinball machines and arcade games..and struggles with auto repair...watching you struggle with the PROMS was pure joy

I was with you on the whole trip man and that was great I had one when I was a little bit younger but I'm 63 now so I'm a little bit older is fun making that trip again just have a good one.

Gotta say, sittin here on an aussie Saturday afternoon enjoying a beer, and watching Derek work his magic, is a darn good day ! Ohh, and a fella did a pretty darn good job on the exhaust fitment there too !

Dereck, you are the wizard, the magic man, the grand master! A fellar can certainly learn a thing or two from you. Almost forgot to say, What a brave man you are. Your wife & kids are lucky to have you too.

I had a 1971 El Dorado with the 500 CI engine. Loved cruising that boat.

I'm glad you kept the EFI even though it's a PITA. Most of the ones I saw and have seen had 4 barrel conversions or permanent 8-6-4 deletes. Chrysler had the exact same issues with their early Bendix EFI in the 1981-1983 Imperial, and most of those got scrapped for a good Holley as well. Dealers even offered factory conversion kits. Replace the fiberglass extensions and it would be a good Sunday driver for lunches or going to church. FYI -- retrofit kits for the AC to R134 are available, if you want to keep it, but many of the interior AC parts such as the evaporator are no longer available anywhere. I had an '87 Fleetwood in the shop years ago that was owned by a nice older gentleman, we had done the 134a conversion and it needed a condenser, looked for 6 months and had to resort to pick-n-pull.

I love the 2 door coupe .80's caddy almost bought one of those.

The box you pulled said Remanufactured on it.

Really enjoying this series on the 8-6-4 Cadillac! Hope you keep up with it.

Hi Derek, I always enjoy your shows but this one brought back especially fond memories. I separated from the Air Force in January of 1982 and my first job was selling Cadillacs and Oldsmobiles. My brother was the service manager at the same dealership and we rideshared on many occasions. This was a rough spell for General Motors due to back to back to back flops in the form of 5.7L diesels, 8-6-4 and HT4100 mistakes. You always impart knowledge combined with risk taking which leads to interesting episodes. Best of luck and keep up the great work.

A guy looks at what's going on, and well, been there, done that. You're awesome. Hats off. Had a few wobble pops. I'm old. 70. Thanks.

Definitely remember that. Index Cards and the Dewey Decimal System. I feel old now.

Derek it is a pleasure to watch your passion for making things GO! Another wonderful video!!

Happy that you made this thing run Derek. Congratulations on the beep boop swap. That seat drill trick is a good one! This is a proper car for a big guy. Best of luck.

My 78 was also known to wake me up in the middle of the night when it was humid, the moisture would somehow set my horn off all by itself, so I would have to disconnect the battery, my neighbors loved me😂

Nothing beats VGG!

The Displacement on Demand was a mind blower for me when you first worked on this car,i always call my dad and fill him in on your episodes,i thought it was only 07 to now where they did that on GMs so to learn that on your show i was amazed lol i grew up around old school cars but learn8ng new th8ngs always excites me,keep up the good content!

I love that reaction from you Derek...Its ALWAYS the same when you've been battling and all the sudden, you get the car to fire off.

55:54 Those caps look good, but I like the spokes, good video thanks for showing sharp looking Cad.

Looks WAY better with the wire wheel covers! 🚘

Beautiful job on the exhaust!!!! This is such a cool car. Thanks for working on it

Derek I hope you see this, I greatly appreciate all the hard work on your videos lately, but please next week take a breather and spend some quality time with your family.

The relay convenience center 😂🤣 The technology a guy has to deal with in this rig is simply breath-taking.

Hello Derek and family 🎉 I hope you enjoyed af peaceful and enjoyable Easter Sunday! Back in the day , a neighbor of ours bought one of these brand new and i initially they were quite happy with it. That is, until one fateful night when at 2am or so the multiple cylinder engine short circuit edges and burned their beautiful home to the ground! A passing motorist saw flames and smoke billowing out the garage windows, and banged on their front door until someone answered. They all made out safely and in just the nick of time!

The tire indentation you commented on at the 50 minute mark is normal on radial tires. It's where the belts overlap and some tires/brands show it more. VERY common on Goodyear and Goodyear manufactured tires (Douglas, Kelly, etc.). As long as it's an indentation, and not a bump outward, it's normal.

The muffler removal flashback😂😂 was gold!!!

Such a beautiful car. Hope you put the wire wheel caps back on.
