Just a theory here but.......If your source of iron IS timing chain wear could it make any sense at all that the longer you run it the less it wearsuntil the point of failure?
No. The tension doesn't go down 'cause there is a tensioner in there. Wear _accelerates_, because the rollers no longer match the gear tooth spacing, and the hogged out holes in the rollers have more point pressure on the pins they spin on. -- Jim
