That's what I would do. I noticed that the packaging on mine looked as though it had been laying there for a while. Let us know if it's better when you get the new one,

 

How do I set this up if my car has a catch can and an SC? Is the catch can still needed at this point?

 

Nice writeup

 

Yes. This valve won't reduce or prevent oil that escapes the crankcase from getting into the intake manifold. I don't have a catch can yet, but I can tell you how it would be plumbed at least:

From valve cover to input of catch can, from output of catch can to Supra PCV, from Supra PCV to intake manifold.

 

Thanks!

 

Not quite.

While your setup will prevent boost into the crankcase, it will not create a vacuum in the crankcase (which the krankvents do). The jury's still out on whether that's a true benefit or not. Some have reported a decrease in oil consumption, and surmise that such a vacuum will create a better seal b/n pistons & rings.

 

My experience is that too much vacuum in the crank case = bad, which the front crank vent seems to cause.

 

So I take it you've had the krankvents on your car?

What "bad" things happened?

 

Hey guys,

so a 5/8" to 3/8" reducer will work. Problem is, so far I can't find a plain old reducer. I had to use two barbs and a coupler. So it makes for a hefty piece of brass to get all the tubing joined. I'm the hunt for the right reducer. Once I find it I'll post again.

 

I also used a supra pcv valve... no complants here.
