mk3 8v gti, list of problems goes on n on :(
« on: 13 April 2012, 21:10 »
So i bought a mk3 8v gti but i didnt realise how much crap it needed done :S
It takes a few turns to get it started but it eventually starts.
Once its goin the oil light flashes on the dash and the engine sounds like a transit van!
theres a big hole in manifold behind the engine big enough to fill engine bay with smoke so im assuming thats y it sound like a van lol.
the biggest problem tho is that the things like a freakin smoke machine :s the amount of smoke that comes out of the exhaust is unreal
pure white smoke and its constant, any ideas what it could be? iv got the chance of a 16v engine for £150. should i js swap it?
any info would be apprecited.

Sounds to me like your spark plugs are on the way out if you ask me, either that or your cylinders are down on pressure! have you checked your oil level aswell?
Mk3 Mad!

16v is'nt a straight swap,it's quite a lot of work.

Sounds like head gasket,cracked head etc.why not just get another 8v engine,they are not dear.

Start with the basics, get the compression tested as a 1st step.

ok so was cleaning the engine bits n bobs and found my air intake hose had oil in it, is the maf supposed to be black? i tried cleaning it anyway lol how do i get the plastic circle off of the top of the engine without breaking it?
theres also good compression on cylinders but dont think much oil is getting to the top of the engine :S
i took some vids il upload them now. engine sounds like a transit because of the hole in manifold
