Help I have engine oil leaking from my exhaust pipe.....What does this mean? Its smoking white smoke while idling and blowing white smoke and oil when driving it. Can anyone tell me what this might be and what to do? Changed oil did not see water in oil, oil was just blackened. Please help!!

 

the white smoke is oil burnin!!!! could be valves???? rings???? needs to be rebuilt.....asap.

 

White smoke could be blown head gasket, does it get hot? or has it gotten hot? Usually oil smoke is a darker blueish color. Have the compression checked and also have a pressure test done on the cooling system..........places to start.

**************No water in the oil still does not prove 100% that a head gasket isn't bad, depends on where the gasket may have ruptured between the head and block*****

 

Agreed! Oil would be a bluish smoke, and smell like it. A white smoke points to burning coolant. It may have a "sweet" smell.

Blown head gasket or (ghast!!!) cracked head!! Has it ever been overheated? This will lead to the H/G problem, and, while less likely, could cause the head/heads to crack.

compression test and coolant pressure test will, indeed, get you going in the right direction.

Pressures among all cylinders should be within (ideally) 5 psi of each other, but if you have two cylinders that are next to each other, with much lower readings than the rest, that points to a blown head gasket between those two cylinders.
If you have one cylinder that is low, it could still be a blown head gasket. It's just that it may have blown out near a coolant passage......hence the white smoke.
If you need to add coolant more than usual......this is your sign! And a coolant pressure test will confirm it.
