Q: Smoke coming from exhaust

asked by on January 26, 2016

The exhaust is smoking and I have an oil leak.

Hello, it sounds like you may have a gasket or seal leaking on your car. Smoke in the exhaust could indicate 2 things: you’re burning oil or you’re burning coolant. If you’re burning oil that usually means your valve seals and guides are worn out. If you are burning coolant that means you have a blown head gasket. Oil burning will be blue in color and will not smell. Burning coolant will be a white grey color and will have a distinctive odor. If you’re burning oil you could have a clogged PCV valve well. Either one of these problems more than likely is going to require a complete engine rebuild to solve.
