That's really not what I was trying to convey. I never said it would fix it, just pointing out there are things to look at here that should raise an eye brow. When I said sketchy, I wasn't talking...

Makes sense, The set of Comp S's with the correct oil band in dad's engine is the Shavers I believe, and the old set of Johnsons bought from Comp probably 15+ years ago that came out of his previous...
