I have a 1994 Mazda mx-6 with the 2.0 liter four cylinder and i recently put a ractive intake on it. When i did that i replaced the hose that went from my valve cover to my intake with a breather. Lately while sitting at stop lights i have noticed it smells like burning oil in the car and there is smoke coming out of the breather. Sometimes it is just a little but other times it is a considerable amount. Anyone have any ideas as to what this might be?
