Understanding Engine Gaskets

Before we dive into the buying guide, it is essential to understand what engine gaskets are and their importance.

1. Compatibility: It is crucial to ensure that the sealer is compatible with your vehicle’s make and model. Some sealers may work better with certain engines than others.
