Yes, it seems like it has not been run as Brokenhead mentioned. I took the remaining 5 pistons out tonight. Each one looked better than the next, I don't get it. All six piston sleeves have surface marks that look fresh like it was recently honed.
When I purchased, there was little know about motor. Only that it knocked, so it was removed from car/truck whatever.
I mentioned that I found a pushrod loose that would explain the knocking, but here in my little/No engine building experience is the problem...This was the the second from rear of motor piston crank rod, watch the video, then in lower left corner click on the shims that were in that one.
