Cover Head Gasket

A head gasket is a crucial component of your engine. It sits between the engine block and cylinder head and seals them both. Its main purpose is to keep oil and coolant from mixing, as well as maintain compression in the cylinders. However, over time, the head gasket can fail, and you might need to replace it. In such a scenario, you have two options: replace the head gasket or cover it with a head gasket cover. In this article, we shall examine both options and see which one is a better fit for your vehicle.

Head Gasket Cover

Head gasket covers are aftermarket products that sit on top of the existing head gasket. They are made of a rigid material and designed to cover the top side of the head gasket. The cover is fitted onto the cylinder head and bolted down with the same bolts that hold the head gasket in place. The head gasket cover is typically designed to fit a specific make and model of vehicle. Some of the benefits of installing a head gasket cover include:

Protection from further damage: A head gasket leak can lead to overheated engine temperatures, which cause further damage to the engine. Installing a head gasket cover can help keep the engine cool and prevent further damage.

Cost-effective solution: Head gasket covers are cheaper than replacing the head gasket, making them an affordable solution for some people.

Easy to install: A head gasket cover typically does not require any machining or special tools to install. You can remove the old gasket, clean the surfaces, and bolt on the new cover.

Increased performance: Some head gasket covers are designed to improve engine performance by increasing compression in the cylinders. This can lead to better fuel economy and more power.

Head Gasket

Replacing the head gasket is a more involved process than installing a cover. It involves disassembling parts of the engine, removing the old head gasket, and replacing it with a new one. This requires special tools, such as an engine hoist, torque wrench, and gasket scraper. Some of the benefits of replacing the head gasket include:

A permanent solution: If your head gasket is leaking, replacing it is a more permanent solution, as opposed to covering it up.

Better sealing: Replacing the head gasket with a new one ensures that the cylinder head and engine block are tightly sealed, preventing oil and coolant from mixing.

An opportunity to inspect the engine: While replacing the head gasket, you can inspect other parts of the engine to ensure they are in good working condition.

Increased resale value: Replacing the head gasket can increase the resale value of your vehicle.
