I have posted here B4 re: sleeve installation. Anyway, after replacing sleeve seals because of collant leaking into oil, I experienced severe collant leaking into #3 combustion chamber w/ engine at rest & filled w/collant. After much testing and head scratchin, I found that the #3 sleeve has a creak ~ 2" long around the top about at the height of the lip. Now after the fact, It seams that it should have been easier to find. I used powered chalk blown into the combubtion chamber w/ compressed air to trace the leak. Any way, I had searched the forum for ideas to solve this & did not see this problem specifically. So that is why I am sending this post. Friends, it's FYI. KB
