Larry, 274k miles, only have maintenance record in booklet completed up to about 175k miles, almost all dino oil (Shell) but some Mobil 1 as well.
Once I get this project running, and the memory of the expenses thus far fade a little, I'll probably install a new timing chain. If I can get access to a good dial indicator I may try to measure the chain wear using the official method. -Max -----Original Message----- From: mercedes-boun...@okiebenz.com [mailto:mercedes-boun...@okiebenz.com] On Behalf Of LarryT Sent: Thursday, February 18, 2010 6:01 PM To: Mercedes Discussion List Subject: Re: [MBZ] OM606 Timing Chain Wear Measure Hi Max, How many miles are on the engine and what kind of oil has been used?
