I've been having a problem loosing small amounts of coolant after each drive. Car is not overheating, its not pushing coolant out of the overflow tank, not smoking. But every time I drive the car I checked the coolant. I would have to add about a cup of coolant. I started fully inspecting everything. Re-torqued the head studs also. I saw a small drop of coolant on the bottom of the T-stat housing. I pulled it apart installed a new OEM gasket back, put it back together and its was still leaking. So I talked with Nick(Assualt187) and he mentioned double checking the T-stat housing for cracks. I have been around these cars for 8 years now. I have never heard of that happening. haha. I pull it apart and bam what do you know big ol' crack right in the mounting surface and a long crack inside the housing too.
So I'm off the car graveyard to find a new housing.
