thought I'd throw up a picture of my catch can to add to the different methods. I used the stock hose turned up, and then used another section of hose to go down to the pvc. I also left in the filter element, because that is what lets he oil vapors condense and drip down...

doesn't have too much oil in it so far, maybe 1/4 inch after 100 miles, but its better than burning that much. I am thinking about taking off the top of the plenum to clean it out too...

 

Where did you find that nifty little filter for the drivers side vent?

I assume it has a 5/8" diameter tube out of the bottom so it fits in the tubing that comes out of the valve cover... right? I'm doing this in a G, so my plumbing might be a bit different.

 

That's good stuff. I did my mod last month but haven't test driven the car. I did both the catch can on the passenger side and breather filter on the driver side. I drove last night and when I got home I noticed a very very small drop of oil..... it works

 

Went to Lowes and Home Depot and neither one carries these, anyone know anywhere else?

 

Well your right it does have a 5/8ths inlet at the bottom of the filter but I don't know where I got it,sorry... I just had it laying around my shop, I think it came off an evo... And than the tubing was molded tubing that came from autozone and I just cut it....

And as for the eBay catch Cans I think they're just as good as the home depot style, neither have really anything in them to help condense the oil vapor, they both kinda just let the air pass threw and let the oil vapor condense itself inside the can. The only thing is the eBay style is a lil bulky so it might be hard to find some room in the engine bay...

 

Thanks...

I ended up getting a K&N crankcase filter with a 5/8 inch inside diameter. It slid right over the tube coming out of the valve cover.

I want to put the 'mini' filter on the drivers side... but I'm confused on where the hose that is hooked to the intake hose runs to...

 

Just thought I would throw in my 2 cents, got my breather filters from advanced auto, all other parts from Home Depot

 

Any cons in venting both sides to atmosphere?

 

has anyone that vented the driverside to atmosphere gotten a CEL?

i got a CEL from a leaking catch can on the pass side ..

 

Other than a bit of a smell ,I have had no issues of venting both sides.

 

so whats the purpose of the catch can in your setup?

 

short answer no... your motor will still be doing its job with pressure, with no obstruction of flow...

did you cap the hole on the intake pipe off? you shouldn't get a SES.., from a breather filter. If your catch can was leaking than you have a vacuum leak, which could cause your SES.... what code was it?

so the oil doesn't soak up into the filer and leak all over the motor and your driveway... so to catch as much as you can before the filter

 

Well its a new set up on my car and has evolved over the process of this thread.. From what I can gather from prior info that the majority of the motor vents through the pvc valve (passenger side) and that there is very little oil or oil vapor lost from the drivers side. Now as I have said this is a new set up and I will be watching it close if it turns out to be a flop then I will post it up. Now did it help ,humm not sure ,did it hurt ,not sure ...... But if You or anyone knows something I have missed then please by all means set me right, cuz nobody wants a busted ride ...correct

 

ok what i dont understand is that the HR guys are putting a catch can on the passenger side one, but isnt this PCV also on the driver side?

 

Since it goes from the crankcase to the upper plenum This should be the correctly direction of flow right?

About to install one on my Z. Long over due!

 

You got it

 

read my post again, i did mention "This", which is what's suggested on the first post.

oh, if you're talking homemade cheap stuff, well yeah, u can do it with a soda can if you want and that would save the $12 filter you mentioned.

Weapon-R CC cost $40.. and that's off the shelf.

 

Where are all these oils going if there wasn't a catch can to catch them? And if it goes into the engine, is there a way to clean the oil off the engine if I dont want to install a catch can?

 

Goes right back into the intake where it gets burned up. If you want to clean it you can remove the intake cover and wipe it up with a towel.

finally remembered to take a picture of mine.
