What's the engine? Just curious, I'm guessing a good-ol Chevy.

|vinniekq2||I had one engine that the chain was so stretched that it was hitting the cover.It did not run well. There is a very good reason why replacement chains are double and gears sets are metal. So many reasons to change timing chain sets.|

My 2 cents worth
If the engine is apart I change them with new gears and a double roller chain. If it is a SBC with the nylon teeth change it. To check with out pulling the engine apart I pull the Dist cap and watch how much the rotor moves when turning the crankshaft back and forth with a socket and breaker bar on the big pulley nut, . My guess is if it has more than 5 * i change it.

timing chain ?
How much slack in a tc before it should be changed? Tia, Dana
