Mott: Your timing chain was replaced at 65k? And for a cost of $1000? Those are both absurd and you got ripped off
joseph c: It's 21 years old with 185k and has a single-row timing chain. On an engine with overhead cams and a single-row timing chain, 100k is typically the accepted interval. If you know how to measure the stretch itself (Probably similar to the procedure listed
here), do so. If you hear slap, usually a new tensioner isn't enough - even with a weak tensioner a new, tight chain won't slap. Measure the stretch, then you can tell.
