I have just purchased a 95S420 with 330k-kms (200k-miles+/-). Original owners service records do not show that the timing chain/guides have been touched. It probably is a ticking time bomb, but money being tight right now, I will address in the near future.

Has anyone compiled a list of parts necessary to do this job, like gaskets, bolts/nuts etc. I will probably replace the tensioner and water pump too!

Thanks in advance.
