A local friend of mine has been running a BMW cyclonic CCV separator on his 1.9L diesel with good results. The separator is used by BMW on a 5L engine and they use two- one per cylinder bank. Inlet and outlet are 3/4", there is no internal filter media.
My CCV is stock but I've been thinking about a CCV mod when I rebuild the turbo.
Any thoughts on using this on the 7.3L? I'd rather not run multiples in parallel because that is too complex.
Makes perfect sense to me. But if they spec two for a 5L motor you may need a jumbo single version to handle 7.3L of displacement. I'd be very curious to know if this works.
Are BMW running 2 because they just put a CCV on each head?
The issue is how restrictive it is. The cyclonic effect may be even more cyclonic with more displacement running through it. It's a cheap part. Put it on and hook up some sort of pressure gauge on the inlet or outlet pipe. Any restriction will show up as positive pressure meaning a fail - not too much money wasted to try it.
Would you catch the oil is a sealed container? If not we hit a recursive loop

I'm not sure of their reasoning for 2 on the 5L, will ask my friend if he knows.
I would run the drain to a catch can, BMW returns it to the sump.
