A car engine gasket is a seal that prevents fluids from leaking from the engine. Gaskets can fail for a variety of reasons, including age, wear, and tear. When a gasket fails, it can cause a variety of problems, including:

* Oil leaks
* Coolant leaks
* Exhaust leaks
* Vacuum leaks

If you suspect that your car has a failed gasket, it is important to have it repaired as soon as possible. A failed gasket can lead to serious engine damage if it is not repaired.
