Engine oil in the tailpipe Signs of problems

If something other than exhaust is coming out of your vehicle’s tailpipe, it could be a sign of a problem. In the case of oil in your exhaust, it is important that you address the problem immediately. Keep in mind that almost any sign of oil leaking from the exhaust system will require a professional evaluation.

PVC valve clogged: oil in the exhaust pipe

The PVC valve allows controlled amounts of internal engine gases to be vented into the combustion chambers, allowing them to burn out. When clogged, it can cause the engine to pressurize internally, forcing oil past important seals and into exhaust flow. This can be accompanied by bluish smoke, reduced fuel consumption, and oil-fouled spark plugs. You can easily fix this problem with a simple valve replacement.

Worn valve guides: oil from auto exhaust

Valve guides are an internal part of the engine that help control the flow of gases to and from the engine. They are lubricated with motor oil and have seals around their shafts that can wear out, allowing motor oil to seep through them. When this happens, the engine oil passes through the worn valve and enters the engine’s exhaust gas stream, collecting in the tailpipe. Usually this problem will be accompanied by bluish smoke coming from the exhaust.

Blown head gaskets: oil through the exhaust pipe

Head gaskets seal the engine “heads” to the block. They are part of the intake and exhaust system and seal the many fluid passages between the headers and the block. When a head gasket fails, fluids can escape past the seal and into the exhaust stream. This problem is often accompanied by overheating, reduced power, poor fuel consumption, and erratic operation.

Worn piston rings: exhaust pipe oil

Pistons are the part of the engine that uses the energy from fuel combustion. The ignition of the fuel mixture pushes them up and down in their holes, providing energy to move the vehicle. They are sealed in their bores by piston rings around their circumference, which are lubricated with motor oil. When these rings wear, oil and fuel can leak into the exhaust system. This problem will be accompanied by white to bluish smoke and a noticeable loss of engine power.

Hole in piston: oil in exhaust pipe

The pistons directly use the energy of combustion. A piston that develops a hole in its surface allows gases and oil to escape to the exhaust. This problem is often accompanied by smoke, malfunction, poor performance, and engine noise.

Cracked engine block – oil in exhaust

An engine block is the block that houses all the internal parts of the engine and is filled with passages that control the flow of fluids to its various working parts. A crack in the engine block allows oil to escape to the exhaust in a wide variety of ways and is always a serious problem. This problem is often accompanied by overheating, loss of power, erratic operation, and engine noise.
