Challenge - Getting the correct Head Gasket
A powerful and reliable engine, the Duramax 6.6L diesel engine is found on many Chevrolet and GMC ¾-and 1-ton trucks and vans. With a confusing array of engine variations and head gasket design, selecting the right head gasket can be a challenge.
Multi-layer steel (MLS) construction is the one common characteristic of all five OE head gasket versions. GM has used two different MLS designs – one for 2001-2004 models and another for 2005 and newer engines. Within each of these base designs are three additional gasket grades or thicknesses. To further complicate matters, technicians must also choose from two separate gasket thicknesses for engines that have either been over-bored or over-bored and deck milled.
To help identify these gasket variations, GM uses a hole and slot system which is located at front end of the head gasket.
