    IF the issue is the same as my truck; the cause was an over active lifter squirting on the valve cover right in the pcv area. The vacuum would suck oil up into the hose, draining in the intake.
    If you want a cleaner look, just take both valve covers to the intake tube and that way, all you've done with add two hoses and you won't smell exhaust fumes.

    Would the "over active lifter" be the one that ticks really bad on my truck on startup? lol

    that's funny, but probably not; more likely it's not pumping up with oil.
    time to pull the engine and forged it, 383.

    Well, something WENT and I mean WENT this morning...I was headed to deer hunt at 6 am goin down the highway and it sounded like a dropped a valve almost. Ill call it a full out knock, but I know it wasnt a knock it sounded like that lifter got way out of whack just ticking like crazy...or sumthing was slamming up and down. I started coasting and it stopped....didnt come back either but I turned around and went home. You think that was the lifter makin all that noise? It sounded like there was a penny stuck in one of the cylinders. And latley when i have been starting it, its been very "ticky" until it warms up

    Ya I bet its the lifter. A lifter is the only thing that can come and go like that.
    It's not uncommon for one or a few to get noisey especially during cold start up.
