Yes, a plugged tailpipe can cause oil to spray out of the oil cap. When the exhaust system is obstructed, it creates excessive back pressure in the engine, which can lead to increased crankcase pressure. This pressure may force oil to escape from weak points, such as the oil cap, especially if the engine is overfilled or has other issues. Regular maintenance and addressing exhaust problems promptly can help prevent this situation.
