I mostly smell it after a long drive when I open the window, I thought it was coming from the engine bay but I'm not sure.
It improved somewhat after tearing off the hood insulation, but it's come back with a vengeance. I topped up the trans fluid too and no change. Doesn't seem to be coming from the brakes either.
It's vaguely like a mix of rotten eggs and burning grease. Haven't noticed any grease on the exhaust though, could it be built up crud and oil on the block burning off? Or maybe oil or steering fluid leaking onto the engine?
Another theory I had was the cats plugging up, possibly with oil from the valve stem seals. Would a high flow cat fix that? What seems most likely here?
Thanks
