VTT New Product Release Overview!
- Thread starter Chris@VargasTurboTech
- Start date
Im trying to figure out whats the simplest,effective yet correct setup to go by.For instance.i have a bms occ for high side vta.I have a RB PCV checkvalve on low side in valve cover.I want to avoid carbon build up on my valves as best as possible.So would a setup of valve cover breather,running with out RB pcv valve running staight to a catchcan using VTT External PCV Adapter fitting do the trick?
Also dyezak are you saying to have a catch can with breather on top with a one way check ball?So it would VTA but close?Think that sounds like better setup
Few things guys -it's really, really important not to forget the difference between theory and practice, and also temper that with the understanding that temperature, engine health, altitude and your particular components will make up what is part of the system. Ultimately you'll need to install and check to make sure the system works to your needs. If necessary, small adjustments are easily accomplished.
If we put -8 in/hg vacuum without the cyclonic stuff in the way, with a totally sealed crankcase, the engine will whistle -not good. There are two sources to this whistling. The first is your system actually pulling air past the seals in the motor. The second is your ears whistling when you realize you're going to have oil leaks. If you can't pull the oil cap off you have some big issues. You want slight suction or nothing at all when when you pull the oil cap off.
With respect to diagram 2, think controlled leak to control the amount of vacuum the crankcase actually sees. You don't want to put the crankcase under any more than slight vacuum. In fact, vacuum isn't even in and of itself necessary, and too much is bad just like too much pressure is bad. It's necessary to allow the system to pull out the blow-by, and not allow excessive pressure (in either direction).

This isn't a stock motor any more. I wouldn't use that as any more than a foot note or item of interest. Who knows where they even measured that.
The simple answer though, is that if someone wants more vacuum than we're recommending then yes, add a check valve as was previously postulated. The system is designed to have a ton of flexibility in it and is easily adaptable!
We have 5/8" check valves for -10 hose, and one piece -10ORB to -10AN check valves. We do aim to please. Hell, we even have some breather logs to share:

Good post. This is the kind of thing I was thinking of. What configuration(s) for what purpose(s)? Lots of folks running around with a bms occ and RB PCV check valve.

Have to back off on this bc some of you gems are just selecting “local pick up” when you live in East Africa and are thinking you found a top-secret yet authorized way to save a few bucks. Negative. You gonna get yo order cancelled.
If you’re putting together multiple small pieces send an email to [email protected] and we’ll cut you some slack.

^ That’s a good one!
So now Im getting twisted in my underwear...
I’ve got a BMS occ - that’s on the high side iirc. I just purchased the vented, check balled oil cap. That is also for the high side.
Q1: Okay to run both?
Q2: Tell me what to buy for the low side.

This is exactly my question. With the VTT oil cap don’t we just need the low side OCC? And if I’m not mistaken the PCV stock check valve on the high side should not be removed to ensure vacuum in the crankcase when required, which should also address @jyamona ‘s questions.
Stock PCV valve is on the low side. I have had my questions answered, directly and indirectly.
There's a lot of questions pertaining to the valve cover breather.A design that's been out for quite some time in other platforms.i too have some questions posted above that haven't been answered.seems we could be in new territory as to how the PCV works now and what is needed when running the breather.Answer could be as simple as nothing would be needed.if this opens up at quarter of boost then there's no psi buildup in valve cover then I would thing no flow moving for the low side.so part throttle the pressure is always leaving the valve cover.i would like to think so but would like some one more knowledgeable to give some insight on if running a breather nothing else would be needed or a low side RB valve style would suffice,or is even a occ for high side is needed.maybe Rob Beck can chime in here.he seems to be the PCV guru here.
