Burns lots of oil out the exhaust under heavy acceleration. If I baby it, it doesn't burn oil. But if I accelerate moderately fast a massive amount of smoke comes out the tail pipes. I have had vacuum hoses replaced and replace the PCV valve.
My car has 140000 miles.
My car has an automatic transmission.
Hi there. Typically when you have a lot of smoke coming from the exhaust upon acceleration, it’s an indication of piston rings that have worn out and require replacement. However, it is also possible that a failure of an oil control valve or cylinder head valve guides could also cause this issue. In order to correctly diagnose this problem, it’s a good idea to have a professional mechanic come to your location and complete a car is blowing smoke from exhaust inspection.
