oil leaks

Hi there all , happy christmas  to all members,  now more problems with my mk1 golf gti 1.8  aka money pit! i have oil leaking from my rocker cover , after getting the engine fully rebuilt and fitted a std rocker gasket , after engine warmed up i noticed oil running down the back of my engine, i checked all the nuts to make sure all where ok , still leaking so i took all off , i had read on a thread on this site  that a rubber mk2  gasket was the way to go , i replaced it and the rubber one seemed to work for a while but now leaking again at the same spots , what else can i try cheers ??

You could try some sealant around the area that it is leaking from.
I know you are not supposed to need to use it but i had a similar problem and no matter what it tried it always ended up leaking.
After a little sealant was added no more leaks. Mind you i hope i now never have to remove my rocker cover again.
I read somewhere that VW recommend using sump gasket sealer on the rocker cover so that is what i used.

Did you change the studs?
If the gasket is still leaking in the same place it could be someone has over tightened it and bent the rocker cover out of shape.
 
Where is the leak?

Yes you can change to the g60 rubber gasket but you have to use shoulderless studs.

Add 2 drops of rtv sealant at the corners where the Gasket seal goes over the cam.

A 3 piece cork cover uses shouldered studs.
no sealant save for the same 2 drops at the cam over seal edges where they meet the cork.

shouldered studs for 3 piece kit.


non-shouldered studs only for g60 gasket….



If you use the shouldered studs you will have oil splashing about everywhere.

if you don't have a oil windage cover get one


Then on a flat area verify that the valve cover doesn't rock any direction left right rear to front and or diagonally.  Repair as needed.

The area where the studs go through should be flatted and not puckered…so flatten that out.

Use of valve cover re-enforcement bars or strips are needed.

When going back with the nuts, set the torque on the nuts to 87 ft/lbs only..  too light it will leak. tooooo tight it will pucker the gasket and usually leak out the back side as the oil splash will pool in the puckered gasket and drip out the rear…..

I am not kidding at all about over torquing… Learned that lesson after about the 3rd gasket on a diesel in 2 months years ago same time I learned not to use any sealant as it makes the gasket slide as you tighten it down save for the 2 drops at the cam over meets the cork, or rubber.









 

Correct 'Torque' like anywhere else is vital! 😉 👍🏼
