When you see oil coming out of exhaust vents, then it is also possible that your lawn mower has engine damage. There are several reasons that could have caused your engine to become damaged. Some of the possible reasons for engine damage can be a blown head gasket, a broken piston ring, or worn valves.
If your lawnmower is leaking oil it could have a bad crankshaft oil seal. There is an oil seal on both ends of the crankshaft where it passes through the crankcase. The seal is pressed into the engine castings and forms a seal against the crankshaft. As the crankshaft rotates it will wear the seal.
Internal problems that cause oil to leak through a lawnmower`s air filter typically require repair by a small-engine specialist. A blown head gasket is one such issue, and it requires tear down, repair and reassembly of the lawnmower`s engine.
One of the easiest ways to fix the leak yourself is to use a stop leak additive or high mileage oil blend. Such products can soften and condition your car`s rubber seals to stop and prevent further automotive leaks. It may take up to a few hundred miles of driving before the leak is completely sealed.
A common sign of stray blow-by is evidenced by oil on the outer surfaces of the valve covers. This is often improperly remedied by wrapping a shop rag or sock around the base of the breather, which simply prevents a mess but doesn`t address the root of the problem.
The telltale sign of a valve cover gasket that has lost its seal is an oil-covered valve cover or a burning oil smell when the engine is running. As oil leaks from a valve cover, it can contact a hot exhaust manifold and burn. Smoke can then waft into the cabin.
This usually happens when the engine is under load or at high rpm, which is when pressure builds up quickly and needs to be relieved the most. The extreme solution to prevent all of this is to install a vacuum pump that continuously draws the pressure out of the crankcase.
Blue or white smoke coming from your engine usually indicates burning oil, which can be caused by: Overfilling the crankcase with oil. Incorrect oil grades. Operating engine at greater than a 15 degree angle.
