Its been two days. The car has not crapped out on me or the dreaded engine lock that i was told i would be getting because my HEAD/HEAD GASKET was supposedly bad. The only problem im really having now is this annoying rattle,more pronounced when the car is in drive and foot on brake (any other gear or giving car gas rattle disappears). Oh yeah and the heavy vibrating thats so strong it rattles my driverside door (probably the engine mounts).
