ASE-A8 Engine performance Latest 20023 Already Passed If the compression is 5 psi and the oem spec is 140 psi, what most likely is the cause? A, worn piston ring. B, burnt valve. Both A and B What most likely is the cause if the compression doesn't go up during a wet compression test? A, burnt valve. B, worn piston ring. A What most likely is the cause if the compression goes up during a wet compression test? A, burnt valve. B, worn piston ring. B 2. Blue smoke is coming from the exhaust...

Wet compression test If a piston ring is leaking, this type of test will indicate some compression. If a valve is burned, this type of test will make no difference and indicate the same readings Blue Smoke this means the engine is burning oil. Could be caused by worn piston rings White Exhaust Smoke caused by coolant leaking into one or more cylinders, such as when a head gasket goes bad Worn valve guides and vacuum readings this condition would cause the vacuum gauge ne...
