Well I'm not giving up on mine yet, but I'm definitely still getting air in the cooling system. Checked all my hoses, no white smoke/coolant stink from exhaust, apparently normal amount of condensation on the oil cap. Next step will be a block tester I guess. Still runs and drives great after she's been burped, but the bubbles are starting to become a regular thing. Also might have a stuck injector because my oil gets dark and gassy smelling after a couple thousand miles.
A real headache but the boost is always worth it
