Alright, here's the problem.........I have a '93 mx-6, LS V-6. I've just changed the oil sending unit and the car runs great, but when I use the fresh air button in the car, I get a weird, almost burning smell emminating from it. I checked under the hood, and low and behold ther is some sort of white smoke(light and not too bad, but wreaks)comming from what looks like in between the engine and the radiator. Right under the air intake scoop. I removed the air intake scoop, and looked but I can't locate a leak. all my fluid levels are normal, and have been for some time now, but that smell Is unbearable! I thought it might be burning oil, but I'm not sure. I have lost alittle oil though. In any case, what do you think it could be, if the smell/smoke is seeping into my fresh air intake? On recirculate, the air is fine. Could it be my valve cover gaskets? And if it is are they too hard to replace myself? If anyone can help, I'd greatly appreciate it.
