Leaking oil seals at front of camshafts - please help

I removed my distributor caps and rotors yesterday ('92 500SEL) because I am having rough running at low revs. Sure enough they are badly burnded - check the pictures. The rotors still have a '92 date on them - horrors!

But worse still, I have now found the cause of a mysterious oil leak I had been wondering about for a while.

The oil seals at the front of the camshafts are leaking, especially on the exhaust cams. Can I just pry out the oil seals or must I remove the alloy cover they are mounted in?

I am more concerned about the oil seals on the inlet cams - see in the pics I removed one of the magnetic clutches - HOW do I get to that oil seal?

If I remove these alloy covers, I presume there is some gasket where it meets the cylinder head?

RE: Leaking oil seals at front of camshafts - please help

The alloy cover I refer to in the previous post that I think I must remove is clearly visible in the photo with part number 119 016 12 06

Can I safely remove this? - what about aligning it again afterwards.

Very many thanks for any help

RE: Leaking oil seals at front of camshafts - please help

S Class, I can sympathize with you. I too have a leak at that same location (but on my six cylinder inline). Currently, I am having the transmission rebuilt but as soon as that is done, I'll have to tackle that oil leak. Our friends at Mercedes told me that it would cost more than $2,200.00 to repair but I'm certain that there has to be another way. The fellow installing the transmission may be able to fix it for much less.
I wish that I knew more about it - I'd be more than happy to help.
BTW, have you thought of writing directly to some of the more knowledgeable people in this forum by clicking directly on their names? (in case they just don't happen to read your post).
Wishing you well,
MB-SC
