Gaskets will go bad in a matter of time. With the material that its made out of and considering other things that may influence the HG"s life, miles should be the least factor.

A good example would be the transmission mount. Its made out of rubber, but it doesn't break because of high mileage. some people have will get 50k miles, and other will get 150k of rubber life out of them. Time is a better predictor than mileage. Rubber will go bad over time, or at least its not as good as if it was new. Rubber will crack in the long run since its also introduced with heat from the engine.


back to topic: i dont' know if i have the original HG. Bought my car with 146k miles and i only have 148.5k right now (2.5k miles since sept ). I'm just hoping its was replaced though.
