I have the same with 400 k but i replaced It with a more fresh one when repainting the car, It was still going strong and no oil consumption

I have the same engine (axp). Did you have to top oil once a month (500lm/1600km) at all?

how much money did you put in that engine to rebuild with all new ?

The pistons were in pretty good condicion, they still had all the coating on the side skirts and they were all measure and still in spec. so i just honed all cilinders, and fit new piston rings, so far 20k on it and no oil consuption problems and always runing 5w40 oil.

@@andremartins6402 there was warming strips ind the cylinder? And you honed the block at home or in a shop?

Boas, se o motor já esta a consumir muito oleo, provavelmente já tem os segmentos a dar as ultimas, consequentemente vai passar mais compressão para o carter, dai a importançia do respiro/separador do oleo, se já não estiver grande coisa, nao vai deixar libertar a pressao acumulada na carter, o que nao é muito bom para os vedantes das valvulas, eu recomendo comprar um separador novo da concorrençia, é o que tenho feito, nao é muito caro, a volta dos 30/40 euros.

pois mas penso que este motor ja é uma causa perdida e nao vale deverá valer a pena a reparação, já terá muito desgaste interno(238000km). pelo que sei o consumo de oleo deve ter a ver com o oleo que passa pelos vedantes das valvulas sobre pressao. a ponta do separador de oleo até tá com um pouco de agua visivel a mexer-se misturada com a maionese. presumo que para acumular esta maionese está a fazer mistura de agua com o oleo, certo? o motor já fazia uns ruidos que eu presumo que viessem da bomba de agua mas azar dos azares ontem que fiz a revisao (desta vez usei o liqui moly mos2 que para ver se reduz consumo de oleo) e parece que o barulho ficou ainda pior, um assobio e especie de chocalar altos que se ouvem bem, estranho que nao acontece a toda a hora. era bom que mudar abomba de agua neste motor fosse simples.

A maior causa do consumo de oleo neste motor é mesmo os segmentos, os vedantes das válvulas é um problema que advém do desgaste dos segmentos, mas nao é a causa principal, estes motores sao muito barulhentos, muita gente pensa que o barulho vem das toches e das cames mas na verdade vem das saias dos pistões a bater nas paredes dos cilindros. Com o desgaste dos pistoes agrava o barulho

@@andremartins6402 pois é estes motores infelizmente são de fraca qualidade, é pena porque o carro ainda está em bom estado, o motor é que não. acha que podia reconstruir o motor do meu? é da zona de lisboa? desculpe colocar a questão aqui mas aparentemente já nao dá para enviar mensagens privadas pelo youtube. obrigado.

I have rebuild at least 6 engines like this one and no problems on the bottom end.

@@andremartins6402 that's great information, thanks. Do you have some tracking, how many kms those rebuilt engines did? Also, where did you get new crankshaft bearings? Do they fit from other VW engine? Since they are not meant to be changed, VW doesn't list them as spare part.

@@Papinak2 aftermarket bearings, most engines specialist parts store should have this. This are the ones i use, for the Rod- KOLBENSCHMIDT- 77307600 Main-KOLBENSCHMIDT-77534600

@@andremartins6402 Thank you very much

No, is not possible, even with the crankshaft removed.

@@andremartins6402 Ok, I supposed, thank you.

Uso o Shell Helix 5w30 HX8. E sempre ponho filtro original VW. Estou com 280.000kms. E o motor trabalha muito bem.

@@danielmouta4365 E normal berem oleo ou sera algum defeito nos segmentos vw nestes motores?

@@fernandoramalho3644 Eu considero normal. Até porque no próprio manual diz ser normal beber 1L de óleo a cada 1000 Km. Depois, segundo detalhe. Condução casa - trabalho ou circulação citadina exige muito mais dos motores. Convém observar a média da VW.

Just loosen the main caps screws gradually in stages in the reverse order of assembly, start from the outside to the center.

Thank you for the information! I would have done like this. Don't understand this VW restriction about changing the main bearings. Now thanks to you, I will give it a go!

What Root Liners were used? It seems that the motor is not repairable and the liners cannot be bought.

You can replace both camshafts no prob. Just remove the sprockets, then you have two plugs on the valve cover and one camshaft position sensor that need to be removed before you can take out the camshafts. Also you can only remove with the valve cover out of the engine

@@andremartins6402 Thanks for the quick reply. One more question if you don't mind. Doesn't the valve cover wear out overtime? I've heard it doesn't run on bearings, just pure metal on metal with oil in between.

@@danielpotor8156on most engines, the camshafts run on aluminium mains, there little to no wear on this parts as long the engine is well maintained, there are some engines that use bearings on the camshafts mains like the vag pd engine. The major wear is on camshafts lobes, rollers and lifters

Can anyone out there tell me if a vw golf 16v 2007 bud engine can be rebore over size as all info I see says not to remove the crankshaft on these engines

@@andremartins6402 Question: Can I put a motor dohc 16v 6n1 on the Golf 4

Sem oleo

since the rebuilt, is pretty mutch like a new engine, is not a bad engine just need regular maintenance and good oils.

Neste caso utilizei goetze e aprovou bem,nao mas o ideial seria npr.

@@andremartins6402 Ks ou Mahle para esse carro seria bom?

sim

i got 190000km on mine and also hear all sorts of noises. I presume you (probably) have the same issues I had: the sealing of the camshaft bearing and the valve cover will (most probably) be worn out. Replacing and resealing these reduced my oil consupmtion almost to zero - This summer, I drove 300 km on the German Motorway as fast as possible(around 160 km/h) in 3 days - with the oil level being the same when i left home (exactly on the same place). Furthermore, probably your crankshaft ventillation module (=Ölabscheider+Kurbelgehäuseentlüftung) may be leaky as well. If you would fix it, I'd also suggest replacing the timing belts (needs to come off for one of the crankshaft sealings anyway) and the serpentine belts as well as all their pulleys (mine were completely worn out). Round it up by replacing the air filter and use a throttle body cleaning kit (as LiquiM.). Even though I had to invest A LOT - the car is now running better than ever - needing at least one liter petrol less and really being sporty again.

It's part of crankshaft gasket - that's why there's that orange sticker

Hi William, the oil pick up was was clogged, and the engine seized due to lack of lubrication. But yes these engines consume a lot of oil!

IMO, consume a lot of oil, mainly when it are new, after some good thousands of kms, it start to consume less oil., relatively. I was used to say lots of bad things about these engines, but after all these years and having to deal closely with a polo 6n2 1.4 16v, I can say that the engines have proven to me to be very reliable and resistant.

1.4 16v engines are very poorly made. Especially for those golfs mk4. I have one. 1999, 130.000 km. Rebuild or not to? ... Driving quality is very comfort, I like the car. But if you're a golf mk4 buyer, buy 1.6 gasoline or 1.9 diesel.

Oh and, next car will be fiat, for sure. Why? Check out JTD motors. Check te price and design. F... german cars. Ok, Toyota is nr.1, but...

@@brnko394 Had a mk4 1.4 16V, too, from 2002. Got a new cylinder head at 90.000km for € 3.000 from VW. Engine finally died at 150.000km. No VW for me anymore.

@@ReallyFilthyToad what do you think? should I buy a new (used) engine from Italy maybe, tested?

I have a AXP engine ( 1.4 l / 16 v) it still run very well, 260.000 km, 19 years
