Comrades,

Today i changed both rocker cover gaskets and the plugs today on my wrx that I picked up on sunday.

The car was and still is leaking oil that is burning on the exhaust manifold.


After changing the gaskets the car is still leaking oil, the rocker covers are bone dry so we can now rule that out.

The leak is significantly worse when the car is driven in a more spirited manor resulting plenty of smoke from beneath the airbox/ o/s head.

I had the cover of the cam shaft to see if the camshaft seals were leaking but they are ok.

It seems to be from the back of the o/s head and it is landing on the mani heatsheild covers.

The plugs were a lovely sandy brown colour, the coolant is clean and both top ends were clean so it doesn't point to the head.


Please help and advice as to what could be leaking, are there any problems with the turbo oil feed/return pipe? are there any gaskets on the rear of the head for sensors etc?


I need this fixed as this is my main car, i'm going to take the heatshield off on sunday to have a better look but please tell be the common places where these beauty's leak engine oil from.

 

it is the rocker cover not sealed. you need to use good silcone on top of the gasket and they have to be clean enought to eat you dinner off them lol. plus you have to re seal the half moons at the same.

 

Yes I used rtv Sealer on it and the faces were cleaned with a blade.

 

is it both sides or just the one??

 

just o/s.

 

I would bet on the oil feed pipe ,mine does the same thing,they are a pain to get to aswell.

 

Its not drivable as the smoke is to bad it stinks! It has to be done.

Whats involved?

 

check the turbo oil feed pipe and the turbo drain pipe, apart from the rocker these are pretty much the only thing`s that will leak in that area,.

 

Aye, i'll give it a gander.
