A Head Gasket is a component located between the engine and cylinder head. This gasket helps in maintaining smooth working of engine’s cylinders and prevent leakage of coolant and oil into cylinders.
If there is a leakage and oil gets into the cylinder, then the engine can become damaged, and performance of the car will decrease. So, if your head gasket is sealed well, your engine is safe. This blog will guide in understanding the reason of head gasket failure, signs that you should not ignore and how much does it cost to repair head gasket.
Head gasket is made from a variety of material, but it should be durable and malleable to keep seal tight even in high temperature and pressure. If your car is not giving best performance and feels different while driving, it means it requires servicing. Contact Bromley Vehicle Test Centre.
