Alex: Do yourself a big favor. If you have never dealt with a head gasket, take the engine to a reputable mechanic and have them check out the head before replacement. Then they will install the head in the proper sequence, torque the bolts in the proper sequence and adjust the valves if they are solid lifters. You can do this yourself but a diesel engine is not a good platform to be educated on. You will make some mistake and it will be costly. Sorry. Gene

Different engines have different configurations, but for a standard inline four stroke engine here's how it is: The block has the cylinders in it with the pistons running up and down inside them. To close them off to get compression there's a big chunk of metal (the head) that bolts to the top of the whole engine block to seal it off. This is also where the valves are kept. The head gasket is a large flat sheet of sealing material (can be metal or fiber) with holes in it to allow the bolts to go thru, the coolant and oil to flow, and for the cylinders. The head gasket sits between the head and the block - sandwiched. As far as the torques that the bolts get tightened to - it's likely higher for a diesel, but I don't know them by heart. I look it up every time I do a job cause for every car they're different. Just depends on how it's all engineered. But yes, doing a head gasket job on a diesel is almost exactly the same as on a gas engine - just surface differences. If you get a good service manual it will lead you thru the job step by step.
