Welp looks like I might consider trading, yesterday I changed the oil at 113k and it was strongly stinking in gas smells. Mostly wondering if there's a common issue some one knows about that causes this on the v6.

PCV Valve is the first thing to try. Cheap out if that's the fix, no big loss if it isn't.

Not sure but does 3.7 have HPFP on top that might leak like the 5.6 does?

Ah. For some reason thought the 3.7 was. Getting old now that I don’t all about all the Nissan engines.

Lolz yeah well direct injection on those older 5.6's surprised me to read about cause that was more of newer thing at the time
