There are a lot of bad things that can happen in the Honda Prelude sports coupe, and one of them is oil leaking through the exhaust. The Prelude\'s exhaust pipe is meant only to expel exhaust gas and water vapor generated by the engine as a byproduct. So once you start to notice oil on the inside of the exhaust pipe, it means something is seriously wrong with your car\'s engine.
There are many causes as to why engine oil can leak through the exhaust pipes, but in almost all of the cases, the leak is due to worn-out seals in between the engine and exhaust. The engine is separated from the exhaust through a series of valves and seals, and should any of the seals fail, engine oil can seep through the exhaust manifold, the exhaust pipe, and other parts of your car\'s exhaust. This is why once the exhaust starts to leak, the first place you should look into is the engine.
If you suspect that your Honda Prelude is leaking oil, the first thing you need to do is to thoroughly check the exhaust pipe. Put on some thick work gloves and run your finger on the inside of the exhaust pipe. If your finger comes out coated with soot, the black oil-like liquid that you suspect to be engine oil may be simply a mixture of condensation from the exhaust and the soot that has built up inside the pipe.
While soot buildup inside the exhaust pipe may not be as serious as an oil leak, it can still restrict the outward flow of exhaust. Have the pipes thoroughly cleaned in the shop as well as inspected for wear or damage.
Another way to determine if the exhaust is contaminated with oil from the engine is through the exhaust smoke. Start the engine and check the color of the smoke. If black thick smoke comes out, it means that the engine is not burning the fuel properly. But if the smoke has a blue or gray tint, it\'s a likely indicator that engine oil is leaking into the combustion chamber. If the leak is particularly severe, the oil may directly come out of the exhaust in its liquid form while the car is running.
If the exhaust is confirmed to be contaminated with oil, the first place you should check for leaks is the valve train. The valve train has seals that prevent oil from seeping into the combustion chamber, and should these seals fail, the oil can mix with the fuel and contaminate the exhaust. The head gasket is also another place to look into, as a blown head gasket can also cause engine oil to seep into the combustion chamber. Other places that you can look into include the PCV valves, piston rings, and O-rings. Take note that these parts are not serviceable, so if they have already succumbed to wear, they must be replaced as soon as possible.
