Im having weird problems with my car but i cant figure out whats the problem. My car looses coolent from somewhere and i cant figure it out it also get prettyy hotter then normal temp i have clean exhaust and my oil isnt milky but the oil cap is pretty milky. and i dont see any coolent being dripped on the floor. Could this be the beginning of a BHG? Or cracked/warped head? Also once its warm and shut off when you fire it up she starts really rough. With something that sounds like a misfire then clears out a little. I need some expert advice this car is giving me a major headache
