Bob,

Had a similar situation with my old block. Compression tested fine even though compression ring was cracked in 4 places from detonation due to a bad injector. However, I was getting oil smoke under acceleration.
Depending on which cylinder, ie 1/3 or 2/4, could be injector housing gasket allowing oil seepage from one of the oil windage ports.
