I put a supercharger on my car last spring and went driving on a bad tune and my car was kinda doing the same thing. i would let it cool for a day or two and there was still alot of pressure on the system. and no coolant in the oil ,or oil in the coolant or even steam out the exhaust... i found out that i blew a heads gasket.. the exhaust gases were going into the coolant chamber .. But try the over flow first, i bet that will work for you..
