burning oil

holy crap, you would sware oil came from no where. I have done all i can next to rip up the block to find my oil leak. Oil seems to be leaking into my #3 cyclinder and it is getting smoked. I have done compression test and they fail to show anything. i have replaced valve seals with all new umbrella seals and i have just replaced my intake gasket. I can't find out whats going on inside this 5.7. Any suggestions?

im wondering if you have a crack in the cylinder head leading into the intake chamber of the head. unfortunately the only way i know to find out is to have it magnafluxed, which requires its removal.
