Yea stretch is the man to consult for the finer details. I just got through reading some of this thread:

OM617 manifold oil = broken valve guide

Best check this one out when you do this job. After reading this thread I found myself asking myself these questions....Why did'nt I check to make sure the valve springs were installed correctly?....and would valve lapping be considered something I should have expected the machinist to do when he rebuilt my cyl. head last summer? He did charge me for a complete valve job....and I did'nt do it...d-oh

In hindsight I really wished I had access to that thread at the time. I have also wondered if I should be consulting Stretch for everything from now on....man, that guy pays attention to the small details. Forgive me for saying that Stretch should have his own site, for all the documentation he has done here. That in itself is alot of work. If I have'nt mentioned it before, Thanks, Stretch for all your contributions to this site...and everyone else for that matter. Stretch seems to stretch the extra bit on the details...I appreciate it. He is valuable part of this site, and he takes awesome pictures. Roy too, He has always been here and sometimes gets left out and taken for granted cause thats what happens to old faithful. He's gone to great lengths to be there for some of us including taking personal phone calls, wow.

Without guys like these, to offer (free) their knowledge, some of us could'nt afford to own one of these vehicles. They go above and beyond, and are inspiration. Oh new thread idea.
