Re: Cam chain tensioner liner
I have said in the past that I thought the replacement interval should be 100,000 miles based on what I saw on mine. That wear is about what I would expect.
About a year ago I replaced the timing chain guides on my BMW 740iL, at about 175,000 miles, and they looked pretty good still, but had hardened and the retaining tabs broke when I was removing them. I think that it the most important, replace them before they start breaking up. I feel that is the most likely failure mode.
I don't want to achieve immortality through my work...I want to achieve it through not dying.
EX: '01 Black LT, BAT BYKE (Totaled at 110,000 miles)
IBA SS, BB, BBG, 10/10ths.
No bike now, but maybe in the future.
