Hi, everybody. I'm in the middle of resealing a 93 B230ft and want to do the tight squish thing. I'm not planning on a rebuild, just gaskets and stuff. So, I started measuring the pistons poke using a deck bridge and dial indicator and they all seem about 4 to 6 thou proud of the block until I rock them. If I rock the pistons at TDC, I can get them to stick up as much as 11 thou on the sides. A little less front to back.
Should I just call it 6 thou and stop being anal? Should I be worried about that much piston rock as far as general engine condition goes? I tried to center them the best I could, but this is where I stop trusting my measurement interpretations.
Would like to hear what you guys have done.
Thanks,
Dave
P.S.
The point of all this is that I want to get a Cometic head gasket and need to know what size will get me about 35thou piston to head clearance. I can do the arithmetic, just want to see what you guys think about the piston rock. This motor probably wont see anything over 6500 rpm.
