do you put the oil separator before or after the PCV? And I was correct in putting the checkvalve after the PCV?

edit: Just realized the TB line (not the intake) goes to the front pass. valve cover port. So now im confused again.

What if you:
-plugged the TB port
-ran both rear valve cover ports to Catch Can (with breather?)
-made a new line that is - 3/8" size hose from intake port > Oil sep > Checkvalve > PCV > and ends going into the front pass. side valve port

The check valve is installed to prevent boost from coming out of the intake into the valve cover but to suck in vacuum as normal.
How bout it??

 

You really don't need the checkvalve or the separator but that setup will work fine as long as there is sufficient vacuum. I've checked my pcv valve and it will hold up to 15psi on my car at WOT. I've also checked it using my air compressor and it was good up to 30 psi.

 

I think I got lost in all of this discussion....how are you suggesting this to be set up with the filtered catch can?

 

Looks great. Any reason why he used a -12 on the passengers side and a -8 on the drivers?

 

We wanted to get rid of as much as we could. And ECS sent us the oil cap so all we had to do was tap it The -8 just because it was easier to route than the -12. And you would have to tap the valve cover in order to run a -12 line on the katech covers. Many people have different ways to do this. As you can see theres allready 4 pages of it If I didnt have my valve covers I would just loop from one OEM valve cover to the other one. And run a metco breather. Then I would add a check valve for boost and the stock pcv inline also filtered by your choice of catch can. All in all your going to spend a little bit of $ doing this. My first setup was the check valve,AMW catchcan and a metco breather. Problem with my metco is after a little time it was soaking with oil and making a mess. Since I consider my new setup more agressive I choose to delete the PCV system totally and just run -12 AN lines off each valve cover to moroso catch cans. I hope that helps.

heres a drawing of what I was proposing. Would this work and will I need a breather on the catch can? And do I need a checkvalve in front of the PCV?

 

I'm using that system with a breather on the can and a check valve between the pvc and the valvecover.

 

I went ahead and got a mcmaster carr check valve. Ill take pics of that setup when I'm done. I think it'll do fine for a 7-8psi daily driver.

7775K52 is part # if anyone is interested. Oil sep is the standard one from Home Depot.

 

ok, finally! some pics of mine....



the lines from the valvecovers, to the catch can (bottom two) can be seen here,
the line on the top port of the catchcan goes to a breather by the foglight, which cant be seen

of the bottom 2, one line goes to the FRONT passenger valvecover port, and the other goes to the rear drivers v/c port, and dont get them confused with the oil return line going into the oil cap, as they look the same!



a further view




this next pic shows how the port on the intake manifold goes to the pcv valve, and then goes to my STS pressure switch, which closes when in boost. the other side is connected to the rear passenger valvecover port





quesions? feedback?

That looks absolutely awsome!! Not to jump off track but are those radiator fittings -20??

 

Thank You and Yes they are..... -20an.
Its a Pet Peeve of mine with fake fittings so i had to do real ones....
Talk about $$ though.... $45 a fitting and $25 a FT for the hose...

Ok in dealing with the PCV system what are all of you Single plane intake guys doing if its so important. Definatly looking for longevity on this setup.
If we changed the oil every 3,000 miles I don't see how anything would be hurt??

Kyle what that line coming from your Turbo is that anything pulling crankcase pressure???

 

Nice setups guys.

 

That line is my Turbo oil feed line...

I have nothing pulling crankcase pressure.... its just vented to the atmosphere..... with the catch-can there to catch any oil..... because she does push oil under boost.....

I dont wait till 3K miles to change the oil.... mine MIGHT make it 1500-2K....

I'm been searching for a good check valve. Please post the part number or type that you used? Thanks.

 

part # 7775K52 www.mcmaster.com

 

The purpose of including the line going from valve cover to intake/throttle b. is to pull vacuum on the crankcase right, so you get more cleaning of the oil and gases. But with the catchcan hooked up, isn't the vacuum just going to pull air from the atmosphere through the catchcan/breather instead of pulling from the crankcase? Or does the catchcan have a valve?

 

kyle
now on us stock intake guys we can do you set up just different, right? second how?

 

The catch can isnt hooked up to the intake line so theres no breather in that line. Its connected to front pass port and rear driver port. I was thinking of adding one of those mini air/oil seperators (husky) to the intake line but I may just run the PCV > checkvalve > valve cover.
