A head gasket will sit in between an engine block and a cylinder head, inside of a combustion engine. Without it, there will be no seal to cylinders, meaning coolant and oil is leaked, so it’s a vital part and it needs to be in tip top shape.

It’s an extremely strong car part, and that’s why it is one of the most critical parts in a combustion engine. A blown head gasket may mean a new engine is required, but it’s extremely difficult to spot any problems and the usual cause for a blown head gasket is down to a faulty installation or design by the manufacturers.

One thing driver’s will never want to hear about after an MOT is a head gasket, because it could mean you may need to buy a new car all together, however, if the engine is still in good shape, repairs can be done at much cheaper price, so make sure you get yours checked out by an expert.
