Im brining this thread back up because I still have this smell constantly. Again, it smells similar to burnt rubber to me. A few other notes to add . . . it only happens when I coming to a stop from high speeds (60+). I have some oil (I almost 100% sure its motor oil) along the bottom of my front sway bar, and scattered throughout beneath the engine. Its been there since I got my 4runer 2 years ago. I loose a very small amount of oil over the course of 5000 miles before I go to change the oil. So my question is, is this most likely a valve cover gasket? I wouldnt think oil would be able to get all the way down to the sway bar from just a minor leak in the valve cover. Or should I be worried about the head gasket at all?
