I am rebuilding a HM100 159022L (B) 3320D.
The bore measures .004 out of round. Too much? Need to go .010 over?
The bore otherwise looks fine. No scores, no marks.
Thoughts from those of you who have rebuilt these before?
Also, the valve guides are sloppy. I do see that you can purchase oversized valves. Has anyone here ever reamed the guides on one of these engines?
Finally, any suggestions on any specific parts suppliers you like more than others?
Thanks!
