Hi friends, I have a 300e24 m104 and I have an oil leak, as far as it is common in this engine, I think it is leakage through the head gasket, I see it on the distribution tensor, I disassemble the upper distribution cover And seal with glue the "u" -shaped rubber gasket, and still have the problem, the leak is exactly where it is seen in the photo, Is this fugue common?

 

Is it possible to tighten the cylinder head again?

 

No ^ sadly not. It's from the gasket, then it will need to be replaced unfortunately.

 

The U shaped should not be sealed with sealer! I did mine 4 times till it stopped. (the leak at the front by the timing cover)

While I was at it I did the headgasket also. Easy job but not to be underestimated if you do not have the basic tools/time/space. had the leak at the same place you did.

got a new one now somewhere but havent felt like finding it yet haha . I am done for a while
