Oil on Spark Plugs Symptoms. In this video you will learn the common symptoms of oil fouled spark plugs. Oil making its way onto the spark plugs is a serious issue that can cause engine misfires, power loss, hard starting, and poor performance.

I discuss the telltale signs of oil contaminated spark plugs like engine hesitation under acceleration, decreased engine power, excess oil consumption, blue smoke from the exhaust, illuminated check engine lights, and hard starting issues.

The video explains how worn valve cover gaskets, spark plug tube seals, piston rings, and camshaft seals can allow oil to leak past and make its way into the spark plug wells. Oil in this area interferes with the plug's ability to produce a consistent, strong spark which is what causes the symptoms.

Knowing how to diagnose oil fouled spark plugs can help prevent further engine wear and damage. I outline the inspection process to determine potential sources of leaks as well as the repairs needed like replacing worn seals and gaskets. This common engine problem requires prompt attention, so being able to recognize telltale symptoms is key for drivers.

Detecting and correcting an oil fouled spark plug issue quickly can restore proper engine performance and prevent unnecessarily high oil consumption and the potential for engine hydrolock. If you notice any of the discussed issues with your vehicle, safeguard your engine by having it inspected right away. Learn the key trouble signs and solutions for oil leaking onto spark plugs.
