head gasket? i have a 99 camaro ls1 a few months ago while at the track i had coolant blow out of my overflow tank going down the track and this would happen once a month if i was racing mabey well a few weeks ago i went and had it put on the dyno and get tuned it happend on there i replaced the radiator cap along with the thermostat now it is almost everyday i have to take coolant from the overflow and put back into the radiator because all of my coolant is going to the over flow tank... just ran pressure test and it stayed at a steady 16 for 15-20 min i noticed a little bit of coolant around the plastic fins by the sensor on radiator but found no huge leak could anyone tell me anything else that could be wrong also oil is fine
Sounds like a head gasket leak. When you start building pressure it prolly loosing it in the heads somewhere. Do you have to fill it at all? And whats the pressure drop to after 15-20 mins?
