Re: Valve Lash And Polylocks
Hey all. Coming back around on this post, as the engine is finally in and today was the first start up. Didn't take long for some tapping sounds under the valve covers, so I'm going to reset the valves.
Initially, I found zero lash on each valve (rotating every 90 degrees in firing order), gave it a half turn, then tightened the set screw to 20 ft/lbs. Doesn't seem like this held, so want to be sure that I'm doing it correctly. If I find zero lash, give it 1/4 turn, set screw to 20 ft/lbs, then turn both the set screw and nut another 1/4 turn, does this seem correct or will i be cracking Polylocks?
