Sometime when your not busy, pop the hood and remove the oil fill cap with the engine running.

I was floored.

Well folks,
I had the Provent Catch Can installed and over 5400 miles, it caught 2.60 Ounces of oil. Yep, that is it
Well, any oil taken out of the intake is good right?

The Bad: The Provent and hoses must cause a build up of pressure or the Provent vented under pressure as I had a code P04DB(Crankcase breather system disconnected) set many times and after I cleared it there is now a hard code P04DB set and I not able to remove that yet.

On this 4300 mile trip, Every time I had to mash on the throttle heavily, it set the code. It set many times and I finally gave up resetting it and left the MIL light on as it didnt affect performance on the trip.
Maybe one of the other catch cans would work better? I don't know.
The truck did burn a quart of oil on this trip, time for a oil change.
I'm giving up on this setup.
