I bought a 02 Neon recently to build a circle track car.....
I went to the local Napa and bought a battery,car came without one.
It fired up and ran for about 10-15 minutes and it wanted to blow the radiator cap off. Those of you that have done these jobs...(head gasket). Is it a pain in the ***? Im new to the whole fwd racing thing so any help would be much appreciated.........

 

Are you sure it is a head gasket leak? If you haven't already I would check the other (cheaper)options first. thermostat, radiator cap, or water pump.
