rings or heads issue????
so 5.4 said to be completely rebuilt.....sat most likely too long there after.......major blue smoke only on start up....after ignition all smoke is gone. approx 1L of synthetic per 500kms LOL (likes oil) seems to be cylinder #1 with all the issues, every 1500kms I pull the plug and hit it with the bench grinder.....one side of the plug has major (oil) carbon like build up on it so badly the plug doesn't spark anymore. compression tests read 12psi on cylinder #1 and approx 36psi on #2.....that's all I could take. added oil in sparl hole and retested.....26psi in #1 ......rings/piston of heads????I don't know if there is other ways to test methods?
thanks ahead of time

you should have over 120 psi compression. It could be the rings, or it could be bad valve faces. Hard to tell without more info.. How about talking to the rebuilder ?? You could drain the synthetic and try regular oil, but that is some major usage...

Otherwise-that engine should not even attempt to start and run.

Bad tester might mean good engine. Not a bad trade if it works out!
