Engine/Transmission (1994 - 1998) installed FASS, now high blow by??

[WDimig]

ok guys, i just recently installed the fass on my truck, it is the 150/180 1010 unit with filters, @45psi. had some electrical glitched after the install, got those addressed, was driving the truck the other day, and noticed that the truck was smoking more out of the stacks at idle, even though the truck was up to operating temp. while i pondered on that, i also noticed a small amount of white smoke coming out fron underneath the truck, took a look only o discover that it is coming out of the breather tube, no good i thought, i have never seen any kind of blow by at all, started to check things, i found that i was either missing a vaccum line or a cap off of the upper vaccum line assy on the cowl, i ust have knocked it iff when i did the FASS install, my question is does the vaccum pump vent to the atmosphere, or to the crank case on the dodge application? trying to eliminate some possible problems for this blow by.

I remember reading something about this on our trucks,and I think they vent back to the crankcase, but as of late, I have too many senior moments. You may need to do a search. Good luck, and I will be interested in the outcome.

The vacuum pump vents into the gear housing which I believe vents into the crank case.

Make sure you dind't blow the head gasket.
