Good video. I'm currently in process of doing this. I noticed one of your injectors broke when pulling the right side rail. I had three break as well as every injector pigtail. If anyone watching this is thinking of diy, beware of the brittle heat soaked plastic buried deep in the valley of this engine.

Fantastic video! Something to note, clean your engine before putting things together

What can I use to clean out the intake manifold and the flops inside the holes?

Thanks a lot! I've been looking for this.

Fantastic video! Could you please share what the original symptom was that caused you to do the work? My GS300 has a cold misfire on one cylinder, and I’m wondering if it might be a bad or dirty injector. I haven’t yet checked the compression, but I’ve cleaned the carbon deposits and tested the coils and plugs. I’m now upset with myself for not removing the injectors when I had the intake manifold off. Looks like I was 90% there. lol

Is there a specific pattern when bolting back the heads?

My lexus is350 2008, I’m getting cylinder 1 misfire, code P0301. Has new spark plug and coil. Do you think I have a clogged injector? 190,000 miles

So you don't need to disconnect the fuel pump and all the other stuff the official directions state? How hard is it to pull the injectors out of the rail?

Thank you for sharing guys

How do you take that fuel pump metal line out? What size is it

Excellent good job 🙏👏👏

How was the fuel consumption after and the power of the car?

18:26 hello at 18:26, that rod that goes to the fuel pump, how do you remove it, and how did you remove the fuel pump? I am trying to pull it out, but it is not coming out.

I tried twice. But I could not lift up the fuel rails, to get at the injectors. What else do you have to do besides removing the 4 bolts and washers? It seems that the rails have to be disconnected from the fuel line itself. I didn't see that in the video. Can you describe how that's done?

This is awesome! Thank You. Do you have a complete video on how you clean those injectors?

Sorry if this is a stupid question as I am a new DIYer, why do the crankshaft has to be turned when reinstalling the right rocker cover and the high pressure fuel pump? Thanks!

I have a Toyota mark X 2008 which uses the same 4GR FSE engine...this was helpful :) is there any way i can make direct cotnac with you i need to know something...greetigns from the Caribbean :) !!!

Hello , what did you use to pressure the injector, a compresor? Or just put the cleaner on the clear hose?

Hi, May I know how to make sure there is no fuel leak when installing the fuel injectors and fuel rail? Thank you

Great video, I have IS 250 2008 Model and I have a leak at the top of the engine, not sure its because the manifold or rocker covers gaskets , my question is it necessary to change them? Any bad impact on the engine Later on ?

thanks

Is presence of Oil is something normal below the manifold cover ?

Do you think I should change the car battery I don't think its changed in 5-6 years

Hello I’m trying to pull the injector line but I’m having an issue with it coming out, it feels like there is something underneath it keeping it from being pulled out, what might it be? I got it past the studs but now it won’t fully come out

You must be a mechanic? I changed the following in the same Model Lexus 2.5 2007 GSE20R : 6 original spec Denso spark plugs...then the mechanic said the rocker cover gasket seals should be changed (left and right) due to oil spillage on the plugs - MAY 2022 Rocker cover gasket seal change left and right - JUNE 2022 Experienced rough idle for months but car was driving OK but not pulling properly Took the car to the mechanic a Lex specialist and he said your intake gasket manifold seal should be replaced - December 2022 After that and a spark plug connection wire being loose and one other connection the rough idle went away The car was back to being smooth and no rough idle Then the rough idle came back on some occasions but the car was still fine maybe due to me putting in Shell 99 maybe it was cleaning I bought a Forte petrol injection treatment because I heard so much about it especially from the UKpostsr BMW Doctor. Put it in and I think it has made a difference. Car was vibrating on idle and vibrating during the drive. No suspension problems new calipers brakes and tyres balanced and aligned. I thought fuel pump or fuel filter but I think I might be right it is the injectors. On slight uphill the car started hesitating on lower revs and started sputtering Just telling you peeps try the petrol treatment by Forte it might be good for you. The injectors you cleaned were manually done so of course if you are using a compressor its much better.
