I searched on the forum for this and didn't see anything. Who makes the best oil catch can? Can you get inside the Greddy, Cusco, or Perrin cans to add some type of mesh filter? Advice is appreciated.

I think you can get in any of them. I don't think any of them function better than the others......just your call pretty much.

I was all ready to get one, but it sounds like there are two different areas that could need venting, but no one is sure how to plumb both of them. I believe they were talking about crankcase venting and valvetrain venting.

It seems like everyone is doing the crankcase. I also read someone mention about possibly voiding the warranty. I am going to ask my dealer today and I will get back on that topic tommorow.

Now I heard the opposite....people were doing the valvetrain. See...I dunno. Does that mean we need two? How do you/can you hook up both to one can?

Good question. You might try emailing Perrin, they seem pretty good about responding quickly.

**Update**
My dealer said it would not void the warranty, but to make sure and get it installed correctly.

I had the Perrin turbo intake hose installed today. I installed the perrin catch can about a month ago. They work well together. The turbo intake does not have a pcv intake/nipple and I ran it to a t valve joing the valve line and running to the can. I ran the can back to where the shop had attached the PCV line. No problems so far. The PCV was very oily as well.

Ok, this is new to me. What are oil catch cans for? From the comments I've seen it seems like they are to catch the oil from the venting the crank case or the valve train? So does this replace the PVC valve? Also why do I need an oil catch can? Also also why isn't the car plumed this way from the factory?

It is not that way from the factory due to emissions? Wild guess here

The PCV valve in my car was dremeled off the stock turbo inlet. It is still attached to the hose out of the crankcase and now blows to the T connector that is joined by the valve blow off and both drain to the catch can. The overflow on the catch can then goes back to where the PCV and valvetrain would drain{without a catch can}. This only works on the Perrin turbo intake. The stock TI has an extra nipple for the PCV valve and it cannot be rerouted.

Does this make any sense? :eek: I think that is right. I have been consuming tonight and it is late. Please correct my errors but try to be nice. We are all here to learn something....I hope. :D

So is this to say you are now effectively venting both the crankcase and the valvetrain?

That's the only real reason I haven't done this yet....I'm not sure which to vent, if not both.

Yes. The crank line was pretty oily also.

And while we are at it....any gains from the Perrin intake? Anything noticible?

(It's nice having you be the guinea pig! ;) )
It seems more responsive. It is not a big difference to the butt dyno. Also, it is nice having both vent lines going to the can. :D

The stock turbo intake is crap plastic with a smaller diameter than the Perrin. The rubber/plastic end that attaches to the turbo showed signs of melting. It was kind of rippled.

Yikes...sounds like a nice piece then.

I don't know if I'd get it for any reason other than to get this catch can in there now. Is there anyway to hook that thing up the way you have it without replacing the turbo pipe? I'm guessing not.

I don't think so. There is a nipple on the stock TI that you would have to dremel off. Then you need to find some way to plug the hole{that is right at the turbo intake}. I can only imagine the crap that would fall or get sucked through that hole and be ingested into the turbo.

I had a friend that put a turbo on a camaro and it was sweet until he lost a bolt nut. He never found it and it went through the turbo. The next step was a new turbo.

I spoke w/ Jeff at Perrin today. He explained the idea, I added the install details.

Here is the easiest/safest method to add the crank vent tube (PVC vent) to the oil catch can, w/out buying the Perrin turbo inlet.

This assumes you already have the basic catch can setup (on the valve cover vent).

You will need:
1- 1/2" vacuum T connector
1- 1/2" vacuum connector
1- 1/2" vacuum plug*
1- vacuum glue (for extra peace of mind)
6- hose clamps (for 1/2" hoses)
1 ft. 6" of 1/2 hose

*I substituted a 1/2" vacuum connector w/ a 5/8" threaded other end and bought a 5/8" threaded cap. I used plumbers tape and glue, and screwed on the cap; and then used glue and a clamp on the hose side. There is no way that plug is coming unplugged :wink: , and it's way too big to get sucked in. Brilliant!:D

EDITED for EASIER INSTALL (10 minutes)
[Hint: Crank vent hose is the furtherest forward (toward I/C) connection on the inlet pipe, it is a 1/2" tube and has a little grey electric clip on the top of it.]

1) Unplug the crank vent hose where it connects to the turbo inlet pipe. Unclasp the clamp holding the grey plug to the PVC hose. Remove the grey plug and the clamp from the hose.

2) Cut a 4" piece of spare hose and attached this grey plug to it, using the same clamp.

3) Cap off the other end of your 4" piece w/ the 1/2" vacuum plug (or connector w/ thread and cap); use glue &/or 1 hose clamp, to secure the plug. Securely capping this plug is crucial!

Set this 4" piece aside until step 6.

4) Using a 1/2" connector and 2 clamps, take the (now) loose crank vent hose (in the engine bay) and connect it to a 1 ft. (ish) piece of spare hose, using 2 clamps.

5) Using a T connecter and 3 clamps, hook the other end of this newly extended crank vent hose into the (valve cover vent) hose, which is going to the catch can.

6) Now grab your 4" piece of hose (set aside in step 3), and coonect the grey plug back into its inlet pipe clip.

NOTE: You should not get a CEL capping this tube, as the electric clip merely verifies clip connection-NO measure of pressure or flow.

Done!

You now have both your valve cover vent and your crank vent line going to the inside of your catch can, and then going from the catch can back to the turbo inlet (where the valve cover vent orignally connected).

Thanks man, I have been wanting to do this addition to my catch can.
