i have a 93 jdm h22 in my 97 accord ex and at first the car didnt start so i had it towed to a shop who finished up the wiring for me. but now the car starts but it dies out. when you uncap the radiator there is exaust fumes coming out. i was told that this was a blown head gasket so when i took the head off i saw that there was large amounts of deposits on the pistons (i mean they are completely black) what can be wrong? the engine compression tested fine. anything will help thanks!
