Replacing timing chain

[Choppa7]

I've a C180 W202 which has oil weeping from the head where the bolts have failed, I believe this is a common thing?

I'm considering sorting the problem rather than living with it since I like the car and think it deserves an early Christmas treat :lol:

My engine has 125k on it currently and is 1994.

Would you chaps recommend replacing the chain whilst I've got the head off or should that be ok? Or will the chain be fine left where it is but replace the tensioner instead?

Thanks!

Unless you have actual problems with top end rattles both the chain and the tensioner should be OK to use at that mileage.

WEhile the caver is off,, look at the cam wheel teeth and check that they are flat on top and not sharp.

Set the crankshaft pulley up on it timing marks and check that the cams are no more than 2-3mm off their timing marks

Thats great, thanks fellas, just about halved the cost and job involvement from what I had originally thought!
