I know this could start a long drawn out thread of disagreement. But here goes anyway.Good thread. Thanks.
A few question.
Is the PCV needed?
DO people run no PCV?
What does the PCV do exactly?
Is it necessary?
thanks

Sure you can.So the only purpose of the PVC is for emissions?
So if my state doesn’t require my car to pass inspection and I don’t care about the next generation and I have a breather on both valve covers I can plug it?

. And there it is! I was waiting for that.Terrible misunderstanding when it comes to the pcv.
The pros outway the cons. A pcv is absolutely NOT stupid. People remove it and think that it made the engine run better or helped in some other way, It's just not so.
The pcv plays a key role in vacuuming moisture and contaminants out of the engine that would otherwise deposit itself in the oil.
The most ridiculous part is that the pcv closes shut under boost and deletes itself. It only works when in vacuum. So why anyone would remove it is beyond me.
Furthermore remove the pcv and get ready for crankcase emissions to fill the cabin and make your clothes smell like ass.
Personally I can't think of even 1 pro of deleting the pcv. It just makes no sense.
My $.02
So to compromise...............................Develop an internal coolant leak and you will wish you had a pcv. That stupid little valve can save your motor. Then again what people don't know, they don't know.
This subject is terribly misunderstood. Most who delete the pcv have some theory of why they did it but the real problem is something entirely different.
Sorry to get off the op's subject. Hope the pics help.
Good luck
So to compromise...............................
I understand they draw quiet a bit of power, also I understand they may not pull enough vac, but why not an electric vacuum pump? If one can be found to perform adequately, that is.

OK, Generally speaking, I think I'm convinced.What is there to compromise? The PCV system is extremely important. I had mine deleted and then started getting my oil analyzed. Even after two thousand miles, the oil was horribly contaminated. The lab even diagnosed it as a failed PCV system in the report! I hooked it back up and the next report looked like it came from a new car.
The issue with a vacuum pump is they're expensive. Sure, you can grab one from an old F-body, but they have to be plumbed in with a PCV, because the pump relies on the engine to provide most of the vacuum. The pump only kicks in high throttle. It's not rated to run continuously and will fail quickly if run so.
Now, you can run into problems with boost leaking past the PCV because it's a cheap valve. The solution is a better valve, not deletion of the circuit. I experimented a lot with mine and actually ended up with a two-circuit PCV system with two catch cans. One circuit feeds from the PCV hole in the intake through a catch can with a check valve to keep the boost out of the crankcase. This circuit needs to be maintained if you're running the stock ECU because without it, your BLMs get screwed up.
The second circuit feeds off the breathers. and draws through another catch can and into the MAF pipe between the MAF and the turbocharger, with another check valve to keep compressor surge from entering the crankcase. This setup has eliminated crankcase pressurization for me, as well as my rear main seepage. I also don't smell like a gas station after driving my car, and my oil stays REALLY clean. The catch cans are effective, too. I get a watery mix in the one on the PCV circuit, but the intake is staying clean and my oil level isn't changing.
Where do you get these check valves for the breathers? I would assume they are pretty large?What is there to compromise? The PCV system is extremely important.
