hey as the topic states i have a 99 v8. after driving for about 10 minutes coolant will start to leak out of the cap, first slowly, then itll start rushing out if i run the car for a little while longer. i tried replacing the cap and thermo (both are correct ratings) and it still does it, could the tank be warped? what else could it be? i tried a search, but the best i could find was blown head gasket or cap or thermo (which ive done) as far a the headgasket, i doubt that, i just changed the oil and it came out clean. isnt if you get white or blue smoke out of the tail pipes it means blown gasket?

I think this might be your culprit.
