HI,

Is there a smell to the exhaust such as burning oil smell or fuel smell, or a sweet smell?

Customer reply replied 4 months ago
burning oil smell

HI,

Ok, that will be from one of 2 sources - pcv valve has failed or the valve seals and guides are worn.

As the pcv valve only runs about $10 and 15 minutes to install - see attached for location on rear bank valve cover - I would start by replacing it.

If it continues, then you are looking at having the valve seals and guides replaced
