Burning oil
Piston rings or Rich oil .
Head gasket
Doesn't matter what type of vehicle, this indicates an exhaust leak and an oil leak. The burnt oil and the exhaust, get pulled into the cowl which is where the air for the interior comes from! Not very healthy...
Seriously worn piston rings and more than likely a broken oil ring.
A vehicle that emits blue exhaust is experiencing an oil leak that has seeped past the engine seals and started to burn with the fuel. It indicates either a blown head gasket or an engine oil leak.
Unburned fuel in the exhaust system causes the backfire from the exhaust pipe.
What can cause black sooty exhaust is bad valve guides. When the guides are bad oil leaks into the cylinder when the car isn't running. When the car starts it produces black exhaust.
Oil coming out of the exhaust in a 2-stroke outboard is typically caused by the oil-fuel mixture used in the engine. In 2-stroke engines, oil is mixed with gasoline for lubrication, and if the mixture is too rich or if the engine is running at lower RPMs, excess oil can be expelled through the exhaust. Additionally, worn piston rings or cylinder walls can lead to increased oil consumption and further contribute to exhaust smoke. Regular maintenance and ensuring the correct fuel-oil ratio can help minimize this issue.
Usually a blown gasket, usually the head gasket. It creates a seal between the oil and the combustion chamber. When broken oil can leak in and you will have smokey exhaust and a dramatic drop in oil level, or exhaust gas (which includes H2O vapor) can mix with the oil. This is a very serious problem and can lead to severe engine damage.
Oil always worked for me!!! ....You might have blown your headgasket! This means that your engine coolant is leaking into the oil in the engine and it causes smoke out your exhaust.
