Head gaskets like these form a perfect seal between the engine block and the cylinder head, and they're more important than they might look

4. Milky Build-Up Under Oil Cap

There is an easy way to find out if your engine's head gasket has blown. Simply check under the oil filler cap. If the gasket is not damaged, the inside of the oil cap will be mostly dry. If you discover a milky brownish-yellow substance that is similar to the thickness of a milkshake, you probably have a gasket leak. The milky substance is oil mixed with coolant that has seeped past the head gasket contaminating the engine oil. Once your engine oil has been contaminated it can no longer properly protect your engine. If you suspect this has happened, you will need to get a head gasket replacement as soon as possible.

White exhaust coming from your car is usually caused by burning coolant in the engine due to a failed head gasket or other seal

3. Visible Tailpipe Smoke

The head gasket is responsible for coolant flow through the coolant channels of the engine. If the head gasket leaks, coolant might seep into the combustion changers which are right next to the coolant channels. The liquid will be burned along with gasoline. This creates a white or gray smoke that comes from the tailpipe constantly. This is a clear sign that you have a head gasket problem.

2. Rough Idle

The head gasket can also fail between two combustion changers. The engine is designed to keep a high pressure level inside the cylinders. When the head gasket fails, the engine will not be able to keep pressure at the correct level which will cause the engine to not only idle rough but also run poorly. While a rough idle is not a clear symptom of a bad gasket head, it is not a symptom that should be taken lightly.
