Vehicle:
Golf Mk4 1400 S, 60k miles.
Symptoms:
Engine is chucking up oil into the air filter as well as leaving deposits of oil on the ground. Oil deposits are blackened despite a recent engine oil & filter replacement.
Engine starts OK and drives seemingly normal. No unusual noises either.
Anyone have a similar problem or input?

Was it doing this before the oil was changed? It's not overfull is it?
|
It was leaking before the oil change. Been checking the oil level regularly since the leak started. I think it is unlikely to be due to overfilling.
Thanks

Block emmissions control pipework due to mayo type muck inthem after a damp winter is you best hope. Busted or worn rings is your worst possibilty. open the filler when running and loosely place a piece of clean rag over the whole sealing doen firmly. This cloth should be deflected equally in and out, if there is a lot of air pushing out then you have a problem. This could be worn rings or a head gasket blowing into a oil return ( zero pressure ) gallery thus pressurizing the system. A comprssion test and a Fumes HC sniff will help to identify which.

Upon inspection of the engine air filter unit I found in contained a fragment (1/3) of a rubber gasket. It appears cracked. It has a radius of about 4cm. I can't tell where it originally came from though.

Sounds like a blocked oil breather. Had exactly the same issue on a Polo.
|
|
Did the oil breather need to be replaced, or can it be repaired?
