For quite a while now when I drive my Xterra everything goes great until it gets nice and hot. Once its hot I can smell this burning scent. The first time that it happened I immediately panicked since I’ve had overheating issues in the past. So I grab my ODB2 reader and everything checks out fine. I have been driving it like this for a while now because if the truck is not overheating then its not that big of a deal (right?).
Well the other day when I was removing the windshield washer tank I looked deep into the engine bay and I saw it! One of the exhaust heat shields was covered in oil!
Once that starts happening the oil that is on the heat shield will get crazy hot while driving and create that nasty smell I was smelling. Anyway, I was following the oil up and determined that its coming from the passenger side valve cover.
As annoyed that I was to find out that the X was leaking, I was still very happy to uncover what was going on. I hope to finish the valve cover gasket job this weekend and get the video out within the next few weeks…
In the meantime, check out this Xterra oil change video.
