More baby steps... finished up the top row of case through-bolt seal replacement. Many were leaking oil from behind...the o-ring seals were installed over the paint/powder coat just as the cylinder base gaskets were. To make matters worse most weren't lubed/greased by the last engine builder so they smeared and were destroyed during installation.

Supplies for the evening...


One of a few that came out in one piece:


One of many that smeared/were destroyed during previous assembly:


Because there is an oil feed jacket behind many of the bolts I didn't want to get debris from cleaning the outer surface when prepping for the new seal. Not sure what technique you would call this but I stuffed a small plug of paper towel into the hole and covered it with my finger while packing it with the through bolt from the opposite end. Gave a nice seal and just pushed it out with the bolt once I was done cleaning.


New viton seal lathered up with the Krytox GPL 207:




I used a sharpie marker cap to get the new seals over the threads during installation. With all the cleaning and prepping it took me about 5hrs to do the top row. :eek3: At this pace it should be back on the road in 2015.
