PCV valves/Catch cans

[TurboBuRick]

What is everyone using for a PCV valve or valve system.I had an ATR valve inline of the stock PCV and found it did not work well at idle.Breathers seemed to mist a little.I am looking at a change,maybe the RJC piece.Any thoughts?

Kev,

Sorry things got a little of topic. I get worked up sometimes on this stuff. :redface:

A good working pcv does the same thing as a inline check valve. They are easy to test by simply blowing through it. Air should only flow through one way and seal the other way. Just like a check valve.
Some pcv's will leak a very small amount when blowing through the opposite way. Not a real big deal. As long as it seals 90% your good.

If you have a good working pcv and you are still getting vapors out the vc breathers @ idle, you may have other problems.

The atr valves don't last very long before they start to hang up.You can take it off and clean it with some brake cleaner and maybe get it to work again but prolly won't last too long.

You never took the time to even search after I give you the information so I guess, YOU'RE RIGHT it doesn't make power and car engineers wasted their time.

The vacuum pump comment was to prove, suction on the crankcase makes power. See the link now?

How much suction on the crankcase does putting two catch cans off the covers have?
Oh ya, NOTHING

Then again, you have NO PROOF the turbo suction doesn't work and yet I have to prove to you it does work right? That's how the doubters always win, even after I posted specific terms to search for the answer.

BR's dyno testing and new parts development continues... - evolutionm.net

I'll even highlight some statements from David since you won't read it anyways, be ignorant and post that it's not possible for the turbo vacuum to make power and do this face again after your post.

During a run with 35 psi of boost the car was able to pull -.7313 vacuum on that line

637 whp 517 ft lbs. The torque is up quite a bit.

I stand corrected, it was the torque that went up.

Again, if you're going to use catch cans off the breather for a blow by issue, why not make a tad of power and put them inline with the inlet pipe like Buick and others have designed and Buschur proves makes some power.

Nope don't need it.

Not comparing apples to apples. The vacuum pump vents to atmosphere. Your way routs the the gases back into the intake contaminating the charge.

Agreed, accept for after market valve covers that have no baffles and spew oil.

Your right.

Ignorant no. Skeptical yes. I know how it all works. Thats why we are going round and round.

Sorry for the face.

Because I just cant buy that contaminating the intake charge with crankcase emissions will make more power. Maybe I am wrong, God knows I've been before.

Problem is, I don't believe everything I read on the net. I have to experience it and see it with my own eyes. Like I said, I know how it all works. Thats why I'm skeptical on the theory.

We do have a dyno day coming up this spring. Care to bring your car and make a small wager on this? :biggrin:

I have to agree anytime you introduce oil into the intake stream it is not good.Will it make ower,maybe until the oil vapours polute the charge.Vac pumps work but not for my purpose.I do know this, too much vac in the pan will pull oil off the wrist pins and cause serious damage.Thanks for the input,has me thinking
