I'm just wondering, since it sounds like the 3.8's like to go through head gaskets, how often do they go? I've put about 16,000 miles one the car since I've owned it, but don't know if the old owner has had to replace it. It's got 146,XXX miles. I guess I'm just wondering if my car is a ticking time bomb, or if I shouldn't worry. I ask because yesterday I was low on coolant, and I'm hoping it's just a "normal" thing.
