    you really dont have problems with chipping pistons if youre not knocking excessively and you dont do long WOT runs. highway runs are a good reason why people destroy these cars.
    So if your DD is a GTP and you drive it like grandma(my ex) and you still run into this problem? Not trying to be a dick but there has to be a reason outside of detonation.

    there are a lot of reasons you COULD blow up a motor. what did she do to it? run it short of oil or coolant? start the car up and immediately start driving even if its sub zero outside? there is a cause behind it, but what is it?

    There could be many, many reasons for this or none at all. Hell you could even have just had a fluke bad motor...who knows. How many miles were on this when it happened just out of curiosity? How long have you owned the car. It could have been from a previous owners driving habits if you didnt buy it new.
