Re: You've got me scared

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.
That is not an M116 engine. It's a 4.2L DOHC M119. Different engine. You should still look into the health of the timing system as it's got some miles on it now and the M119 chain is a long one that changes direction like all other V-8 chains.

At that mileage I would have the chain stretch checked right away and I might invest in a new chain and tensioner anyway. You probably got the car for a huge discount due to the mileage, and you'll need to invest some of that difference in the car.
