i Have a 94 mustang gt i just bought has trickflow cam forged pistons rods the works. Roush heads, trickflow upper and lower intake idle to 6500 i believe. pretty much i had 2 replace all the vacum lines now i here an hissing noise.Almost sounds like exhaust leak I put on new exhaust gaskets and tightened the exhaust system so its not that. i know the valve covers are leaking, Im hoping for blown head gasket not cracked block. oil gets over full, very very faint creamy efect. Also posible warped intake? could that be letting water leak into my oil. Ill top off the water in the radiator run the car bout 5-10 minutes, and wiill have to add bout a quarter gallon of water to fill it back up, any suggestions?
