Diesel engines can be hard on head gaskets. I get asked about the reliability of head gasket replacements from time to time, and I have to answer them by saying I don't really know what the big picture is, only what I personally know about it.

So, here is a topic thread where we can hopefully learn more about a broader spectrum of repair situations, and what real owners have experienced during their owning the same truck before/during/after a head gasket replacement.

Have you had the head gaskets replaced on your Duramax? What year truck, how many miles before the problem and then after the new gaskets have been replaced. Were there any performance mods on the truck?

Do you believe head gasket replacements are reliable? Share your experiences. The bottom line is... is a head gasket replacement reliable over the long-long haul? Thanks, Jim
