The timing mark floating around as you watch with a timing light at idle is where you SEE the slack in the chain best.

The mechanical test has been preformed and chain has past inspection. Agreed.

As many junk engines I have used, It would be a good idea to replace that chain now while the gaskets are open. I have changed cheaper ones with less slack and I have also had a dozen or more jumped t-chains in 35 yrs running junk by refusing to change it thinking it will last a little longer. roll them dice!

now that it is "USED" and has passed the spec test, what about another 10,000+ miles? is it going to start floating around then? are you going back in?

IMHO, $ well spent on a timing set now.



I like the pro-gear sets from Hughes and SUPERFORMANCE gaskets.
