Guys a lot of this stuff is interdependent, and will be slightly different according to your goals. The easy key-to-victory-path was already outlined with the pics we posted diagrammatically showing several common (and useful) options. Start from there. If you want to tweak it a bit... by all means. This is not one size fits all.

I answered some of my questions but still have couple more.
do you carry the correct vac hose,I don't see it on your site.i did find this,would this be correct?https://www.jegs.com/i/JEGS/555/110920/10002/-1
For the high side getting rid of flapper then there's full flow? It doesn't have to be metered going vta?

We don't have the hose up there by itself -you can use whatever you'd like assuming material/etc is up to snuff.
As far as the high side, as previously written, it depends on your setup and your goals. You don't want too much vacuum in the crankcase or you'll suck in oil past the seals. If you want more vacuum than pulling the flapper out allows, you can add a restrictor or metered orifice.

Hey @Chris@VargasTurboTech I purchased the oil cap breather.

I also have two fittings on my valve cover to a catch can. Would that be overkill with the 3 valve cover vents?
As long as your system is completely external, and you're just venting positive pressure(no vacuum source, all VTA), you can't over do it. The only time you could potentially have an issue with venting too much would be if you still had the internal pcv system and un check valved venting...which would be the same as having a cracked valve cover.

Chris,

I received the oil breather cap today. I really don’t think the hose clamp is needed to keep the filter on the oil cap check valve. Thoughts?

Edit: It looks well-constructed. Nice-looking part. I’ll test it out soon.

Anyone out there running the VTT valve cover yet? I'm very curious to see a red one on a car and to know how hot it gets after some stop and go traffic.

We included the hose clamp for a reason. If you feel that you don't want to use it or it's superfluous, by all means, leave 'er off.

So in that case with the 3 vents I do have. I can just block off both the low and high side on the valve cover? Run no PCV valve at all? Or do I still need to run the throttle body fitting and a check valve to another catch can

If you use any suction source, you need to maintain one way check valves and some sort of metering valve. If you eliminate all sources of suction, and ONLY vent to atmosphere, then you can remove the check valve and metering orifices.

Thank you

Is it still a good idea to have a suction source in the system with the setup I am running?

I don't know what you have, or what you want to run. If I were anyone looking to modify their pcv system, I would do some reading in threads on here, e90post, and bummerboost before taking any action. You need to make sure you understand all the intended and unintended consequences of the changes you make.

Check out jiffy-tite dry break quick connect fittings too. That way you'll never spill fuel if you have to pull a line off to get to/fix something.

Also, google "sae fuel fitting" and you'll see what you're looking for. Lots of options. I think I have the Fragola ones.
