The guy who is doing my Sons heads said exactly what Jerry said about knurling. He said it doesn't work, at least for very long. We explored that possibility when we were using all that oil and he said to forget it and do it right.

On another note, I reread all the replies to this new member and saw NOTHING that could be considered anything but helpful. But all of us who have been on forums long enough realize some people drop in, ask for help and really don't want to hear what they are told, and then they move off. I suspect that will be the case with this guy too.
