Oil leak 95 e320coupe - PeachParts Mercedes-Benz Forum

keep finding oil on floor under engine (front). Have been told that it is common for this engine to leak from a seal behind the a certain cover...? but when is it time to do something about it.

I would say that it is leaking a table spoon each night. Is there a quick fix? Is this generally an expensive scenerio to do it right? Is this part of the head gasket or oil pan gasket? Is it possible for a shade tree mechanic to accomplish?

thanks.

Ahhhhhhh, the imfamous M104 engine leaking problem rears it's ugly head once again.

I recommend using the search feature to answer your questions. I doubt it is a job for the "shade-tree" mechanic.

do a search on m104 head gasket.

Head gasket, even if it is leaking from the bottom front?

Plus, wouldn't I be seeing something interms of the cooling system malfunction or leaking/seeping etc. if it were the head gasket?

Just a question, cause I dunno.

thanks.

M104 head gasket leak is mostly external - you won't see it in coolant...

If his leak is at the front, it is certainly the seal at the timing chain cover where it meets the head.

A leak at the rear would be the head gasket.

This is the part you'll need:

stevebfl had a post about this some time back, can't find the thread anymore. the leak at the front timing seal often involves the head gasket too because that is a juncture of three surfaces -the block, the head and the front timing chain cover. my head gasket leak manifested as an ugly gusher in front. you could be lucky and only have the problem at the cover but chances are that it's the head gasket, since it's only a matter of time with the original design...
