What Happens if My Valve Cover Gasket is Leaking?

But on a four-cylinder engine, it can actually leak into the spark plug tubes and cause misfires. Replacing the gaskets on a V-type engine is a job for the pros. But the valve cover gasket replacement cost on a four-cylinder engine is less than $25 and can be done in about an hour.
