Catch can filling up quick! Serious Blow-Back

[BAMBAMN54]

Just recently took my 135i into Vargas Turbo Tech for billet valve cover and some other goodies. After switching from the traditional pcv with the catch can inlet mounted on the back of the motor the port that goes to the catch from the cover now is in the front. I am getting so much blow back it seems to alarm me! I am filling up my ecs catch can to the brim after 10 mins of hard ish driving. Is this normal? Car has burned 2 quarts of oil in the 3 days that I have had it back from the shop. Scared it could be something engine related. anything helps

Best,
Flynn

Take it back to the shop. That is not normal

That's what I was saying. Something is definitely wrong.

For example my catch can is empty aside from a couple drops through 2 oil changes

That's how mine was before but because they switched to a billet valve cover.

I'm not expert, I just started reading about an OCC as I saw some oil in my IM (I don't think many people with N52s have an occ but it could help) but from what I've gathered it's supposed to remove oil vapors from the blow by gas so it doesn't accumulate in the bottom of the IM or on Intake valves.

It seems like in your case it's pushing a small stream of oil into your occ.

Where exactly is the new ccv on this valve cover? Is it possible that oil is being "flung" let's say toward the inlet of the ccv hose and the blow by gasses are pushing them into the line?

You said it's on the front, maybe oil is being tossed around from the timing chain and gears causing this?

It might help to run another line from the main ccv line downward toward the sump with a check valve of course to capture the bulk of the oil going to the occ. I mean the occ is just to cool the vapors and condense the oil back into a liquid before going to the IM or vented to atmosphere.



Just my two cents and trying to add food for thought. I'm by no means an expert and would hesitate to call myself an amateur mechanic, so take it with a grain of salt.

Thank you for your time and words, it ended up being oil fling from the Timing chain. Moved it to the rear and the rest was history.

Thank you all

That's great, glad to hear it worked out.

Btw are your headlights tinted with wrap or painted?

Tinted with lamin-x films. Just a temporary tint till I can afford bay optiks. Lamin-X are great people though! Highly recommend

Bay optiks are the Cali based aftermarket headlight people right?

I was looking at the bavgruppe ones as I like the 3/4 AE projector.

I like the the little sliver the bay optiks have though, almost like a cuttlefish eye if you've ever seen one.
