07.5 lmm Hey guys so lately I’ve been getting a little puddle or drops of oil at the passenger front tire. Looking at it I see oil all over the frame and looking from under I see oil all around the cold side of the intercooler goin back up. I can’t figure out why I’m getting oil thru there at all. I replaced the turbo last year the only other thing I can think of that it could be is maybe pcv is bad. Was wondering if anyone else had this issue at all

Start with checking the large o-rings (2) on the cold side elbow out of the intercooler to the cold side intake, normal with the factory PCV functioning.
Several will do/have done the PCV re-route to eliminate the oil vapors from going thru the entire intake system, intercooler, turbo, EGR, out the exhaust, etc.

I presume by now this issue has been solved.
When I changed my fuel filter and saw the bottom right front corner of engine soaked w/ fresh oil, I thought oh shit. I had just changed the oil 2 days earlier and it was 2 qts low
Took it to my repair shop ... they said it was the "oil filler tube O-ring"
WTF. How does that occur?!? Any way, just throwing it out there.
