I have Boomba as well for several years. No issues. Definitely a metal ball.

Cool, thanks for the check valve input. super helpful!

So the flow rate through the checkvalve when under vacuum is not a concern? I thought it had to be a controlled flow to prevent idle issues?

The X has a large check valve stock.

So this is what I am thinking with my breather system, thoughts?

That will work although without an OEM PCV valve in the line to the manifold, you might have high idle issues.

That will work perfect Bryan.





He won't. The X has a MUCH larger PCV valve than the 8/9.

Have no plans on using the OEM PCV. It's highly restrictive, the opening is ridiculously small.

It's way bigger than the 8/9...lol


But with the check valve in the line to intake pipe, you're idle will be fine.

So I'm currently looking at a Mighty Mouse catch can which already has check valves incorporated in the top and side so seems to be the ticket!

Although not sure if I want to run a couple feet of pressurized hose from the intake manifold all the way to the can. I think I would rather have the check valve as close to the intake manifold as possible.

Been speaking with the owner and he has been very helpful.

So I received the new check valve so I could see what the internal valve looked like before my other one got destroyed.

All I have to say is FFFFFFFffffffffuuuu this check valve. 100psi capable? Give me a break. no ball.

This.Rubber.Flap is the check valve. I can easily bend it with my fingers, and now it's in in my motor somewhere...

Nope. Nope. Nope.

If its a small enough hole, then even a piece of rubber can handle 100 psi.

Theory is awesome, however in reality it didn't even hold 26psi on my car.

I hope that you find the piece of rubber.
