Slack in Timing Chain...

Is .35-/.40" of slack excessive on a new timing chain/sprockets after 30 minutes of running time after a new install?

My fsm says that anything over .500 needs replacement. That much stretch is cause for concern. Oil is the only thing that keeps it cool. Starve it and it'll get hot quick

Yes, that is too much slack for new parts. What made you take the timing cover off to check?
