The Oil Pressure is 60lbs and has been strong consistently - The only lifter noise, which is very prominent is from the #1.

The Rocker Studs are threaded, and holding steady at the 40lbs they were torqued at -

On the lifter bore, I considered that - but since we are getting good flow out the top of the pushrod that says that it's not bypassing, correct?

Was I correct on the theory on the lifter being a lifter?
