Which timing set?

I figured out where my coolant leak was, it was coming from behind the timing cover. Now that I have it off and cleaned up, I'm thinking my timing chain may be too loose and why not replace it anyway. This was a standard rebuild back in the 80's, nothing fancy. 302 2 barrel. Should I bother with a double roller or just get a standard replacement? Any suggestions on brand and/or part number? Motor will probably need another rebuild or replacement sooner rather than later anyway.

Unless its one of the 'quiet' chains with the nylon tooth gear or there's excessive slack, I wouldn't worry about it. . .

The slack seems excessive to me. Taking up all the slack on one side, the other side deflects an inch or more.

I'd replace it with the same setup. No need to spend any more than you need to.

An inch inward deflection? I'd replace it since you are already there and just use a standard (non-nylon) set since you may want to replace the unit again when the engine is eventually rebuilt.

Thanks. I ordered a Cloyes standard replacement. I'm thinking maybe the loose chain was causing that weird arrhythmic knocking sound I was hearing.
