And i saw that they also ground the piston skirts to clear the crank.whats going on with this motor?
As a young man, I used to buy complete motors until I learned that every seller is a liar. Never again. I want it used up and ready for a rebuild or in pieces. Either one is fine, because the cost is commensurate with the value of the hunk(s).
Your noise could be anything, from a skirt hitting a counterweight to a cracked piston to a loose pin to a counterweight hitting the end of the dipstick to one of the rods hitting the cam to................
