hmm... that doesnt sound good.... does the car have a MHG, or stock gasket? from retorquing, i figure stock.... i dont want to get you worried man, but white smoke is one of the symptoms of a BHG. you should get your coolant checked for exhaust gas (easy test, most shops will have them).
lookin over the security system wiring diagram... damn, this is goin to take awhile.... i have 3 sirens to mount
