[s-cars] 0 compression in 4/5! was-HELP! 4 cylinders just isn't enough....

[Theodore Chen]

pull the head and look.  if you have an air compressor and the hardware
to do a leakdown test, you could pump air into the #4 and #5 cylinders and
see where it's coming out.

but since you have zero compression on those two cylinders, it's pretty
clear that you have to tear down the motor anyway, so i don't see much
point in trying to detective work first.

head gasket is probably more likely than cracked pistons, so hopefully
it won't cost you too much to fix.
