Compare Subaru head gasket repair quotes from specialist garages

Subaru is known for using the innovative boxer engine, named for the horizontal movement of the pistons - almost like a boxer throwing punches. The flat layout of this engine provides better fuel efficiency, and its low centre of gravity makes it more responsive.

In the 2020 Driver Power Survey, Subaru was voted the best manufacturer for safety features for the second year running. And it isn't just cars that Subaru manufactures - it also has an aerospace division that develops and creates parts for planes, including Boeing's 777 and 787 passenger jets.

The head gasket is crucial because it prevents oil and coolant from mixing and seals the internal combustion process. It is under the most pressure of any engine gasket, and it can be expensive when it fails, so it's best to shop around.

Head gasket symptoms to look out for include white or milky oil caused by leaking coolant, white exhaust smoke, loss of power and water or a sweet smell from the exhaust. Blown head gaskets are usually caused by overheating, so keeping your coolant topped up is important. You shouldn't try to drive with a blown head gasket.

A head gasket repair is usually only a temporary fix, especially when you use sealant, and if the damage is too extensive, you may need to book a full head gasket replacement. A cylinder head repair is sometimes required if the head gasket has blown.

A head gasket specialist can advise you on the exact repair your car needs and how much it will cost. Read our complete head gasket replacement guide for more information.
