2006 chevy tahoe LT. It started to blow white smoke on start up when we had hot weather here 90 plus. Talked to mechanics at my work and they sugested valve stem seals . Did those but it didn't help. After a while i started to noticed small bubbles in the coolent reservoir. Shortly after radiator developed a crack and leaked (on friday the 13) added stop leak boubbles went away but not the smoke. Yesterday I checked the compression on passenger side heads 180,190,209,195 . 209 was wet spark plug. Tried to do leak down test. Piston top dead center and air in cylinder . Had air coming out of oil fill cap on 3 of the 4 cylinders checked, the fourth one i didn't do the leak down. Next week going to Mechanics for proper diagnosis. Otherwise the car drives fine. Engine is smooth no misfire or hesitation.
