ok fellas..i bought me a 1990 supra turbo from a fellow supramania member...great seller may i add..he told me that the headgasket of the car may be going..so i towed it back home..added antifreeze(he said he took out some) and left it to run for 1.5 hours and didnt even overheat ..but the exhaust fumes are so strong..it sticks to my cloths..there is no milky residue or any signs of a bhg..when i revv the engine a lot of water comes out the exhaust ..i took a cloth and rubbed the inside of the exhaust hole and its so black..it has all the factory cats on the car also..anyone know why would the fumes be so strong..HG? clogged cat?..by the way when i revv the engine the anti lock lights come on and goes away
