Gaskets & Seals

Gaskets are a very cheap and often overlooked part, but they serve a vital function. Large parts of the engine rely on pressure being maintained. Although manufacturing methods have come a long way, tolerances aren’t at the point where you can get a good seal from metal-on-metal contact. This is why you need parts like LML head gaskets which sit between the cylinder head
and the block. Some, like Duramax up pipe gaskets, can be replaced as standard when working on other parts like the turbocharger. This makes sense as the part is cheap and a lot of the labor is already being performed.

The head gasket prevents gasses leaking from the combustion chamber and also seals the areas coolant and oil are flowing through. As it is under an immense amount of pressure, and as a result, it is one of the gaskets most likely to fail — leading to a situation where you will require an LML head gasket replacement. A Duramax LML head gasket replacement is a long and
complex job, but it is made easier with things like an LML head gasket kit. The kit contains all of the parts you’ll need to carry out a 6.6 Duramax head gasket replacement.

A high-performance engine like the LML 6.0 Duramax has to deal with higher pressures. Because of this, traditional head bolts are usually switched out for far stronger LML head studs. The studs can stand up to the increased forces large, turbocharged, diesel engines produce.

When replacing a head gasket with an LML Duramax head gasket kit, you may also consider replacing the head studs. If a head stud is damaged or corroded, it will need to be replaced. Otherwise, the same studs can be reused up to four times. If you do opt for a head stud replacement, you can also buy a LML head stud kit to ensure you have all of the parts you need and you aren’t left waiting for a vital component while trying to complete the job.
