Hemi Pcv

Hmmm, I never thought about putting the valve on the can itself.

To give some context, when I first did the engine swap I just ran a breather on one of the intake ports and plugged the other. It worked, but it was always messy around the breather. I later decided to put in a DIY catch can (a stainless steel water bottle with some fittings screwed in and steel wool stuffed inside), but still didn't have a PCV valve initially (I'll admit I didn't fully understand the system at the time). So it would have had a fresh air line to the back intake port from the air cleaner base, then other port to the can and from the can to the throttle body base plate. Latest setup just added a PCV valve between the intake and can.

Jumped on the throttle the other day and saw oil pressure drop. Checked the dipstick and it was low. Changed the oil and only pulled ~3.5 and change quarts out of what is likely closer to a 6 quart system. Catch can was totally full. The tough part is trying to piece together the timeline as until recently the car was only driven sporadically, so not sure when I put the PCV in relative to the last oil change. I know my catch can was garbage, so that doesn't help, but still not sure how it filled the whole thing up.

Did a little playing around on it yesterday and found that the idle vacuum with the base plate port fully plugged is similar to the vacuum with the PCV plugged in and open to air (crankcase end of the valve not connected), so I think the valve is working correctly. I got rid of my catch can for the time being because I know it's not designed right. So at this point I think my system is "functional", but guess I won't know for sure until I put more miles on it to see if it uses as much oil. Strange part is that through all of this the car never seemed to smoke or smell like burning oil, despite me seeing oil puddles on the backs of valves when I took the intake off a while back.
