valve stem seals maybe?

daamn..so the rings could have crack or not seated like they were pose to??that sucks cuz he jus finish rebuilding the bottom end....lol

Compression check each cylinder, then re-check them all but the second time around put a cap full of oil in the cylinder and see if the compression rises. If it does, then your rings in that cylinder are bad.

did you accidentley put the piston rings in upside down? putting the rings upside down actually is a old hot rod trick. it gets more power but will burn more oil.
