OM617 camshaft advice req'd
G'day Folks,
I'm in the middle of pulling the engine of my W123 1981 300D OM617 motor apart and I noticed a possible problem with the camshaft.
Can any one advise whether remedial work is required for the following faults.
(My Haynes manual says this sort of thing could be a problem - but it doesn't give a remedy)
The problem I have is that the car has probably sat for ages doing nothing so...
1) Some of the camshaft lobes are discoloured - grey muck on the surface
2) There are specs of rust in the polished lobe surfaces
3) Uneven wearing of the cam lobe followers - when you adjust the valves the gap can be "good" on one side of the contact between follower and lobe, but "bad" on the other side.
I've taken some pictures of the camshaft - I'm hoping the eagle eyed here can see what I mean.
I've got a polishing wheel and compound etc so I could in principle make the camshaft look a lot better - but I don't know whether that would actually help (with any possible problem that I may have).
As usual any help will be greatly appreciated - thanks in advance.
