2006 Nissan Pathfinder Burning Oil Smell
Posted: Sat Feb 20, 2021 5:55 pm
Hi all,
I have a 2006 Nissan Pathfinder with about 130k miles on it. If the truck idles or sits in traffic, you can smell burning oil either in the engine bay or through the air vents in the cabin. The smell clears up when you get moving. The exhaust smells normal, and there are no abnormal engine noises and no oil consumption that I've noticed. I run full synthetic (Valvoline high mileage w/maxlife), changed every 5k miles.
I think the issue is the head gaskets are failing. I see moisture on the exhaust heatshield and the block, which is almost certainly oil. PIctures attached (they aren't great, sorry!) Or hopefully, it's just the valve seals?
Thoughts?
