I just fired it up and let it run from dead cold to 190 without the lower pulley and belts.The noise is not there. It was very noticeable before and not ther now. I will take the oil filter I removed last week to my buddy's shop and let him cut it open and see whats in it.
Hopefully nothing major is wrong. Just built and installed this engine last year. Runs great.
Opinions on this are welcome and appreciated.
Has anyone used these pullies?
