Just want to know if it's ok to run this catch can setup or if I need something better
Its a 3 port sealed catch can, I connected the line from the pcv dat runs from the factory breather box to 1 IN port on the catch can and a line from the valve cover to another IN port and then the OUT port on the catch can I sent that back to the intake manifold to the spot where the pcv would go

Jus a diagram of how it is on the car

 

Ideally you should be running a vented catch can. @Txdragon was running a sealed catch can in the past and I think he may have had some issues - I'm sure he'll chime in with some feedback. @TheShodan also has a sticky at the top of this sub-forum with a catch can setup that utilizes a one-way check valve you may want to look at.

 

I can leave the OUT port to vent to atmosphere it doesn't have to go back to the intake

 

I still have that 100 dollar waste on my car. Lol! I did exactly what you are describing here, and it is no more effective than just slapping on a breather filter and calling it a day. I ran 1 hose to the stock valve cover breather port, and the other is vented to atmosphere. My recent trip to the dyno allowed me an opportunity to see that it is at LEAST breathing during engine load. My recommendation here is: save your money and get a proper vented setup, or just toss on a cheap, 9 dollar breather filter and call it a day. All this mishimoto can is really doing for me is taking up space and providing pure anesthetic value.

 

Wow,lol, well the main reason I got it was to stop too much oil from getting into the intake from the pcv system, I had to be cleaning my intake an trottle body alot, this catch can has a baffel and a filter inside so it stop the oil an stuff from messing up your intake, which is why I got a sealed one so I could connect back the intake vacuum hose to it, right now the intake vacuum hose is not connected, I blocked that off, is it OK to leave it blocked off? All I have running to it now is the hose from the pcv, another ting is oil droplets was coming from the stock port on the valve cover sometimes so when I had d little filter on it wud get dirty

 

Same for me. On my first setup, 17psi from a T3/T04E cxracing turbo, I was purging some oil from the breather filter as well. I had this can installed before any major push from the current turbo.
In regard to how you have yours set up; use your pcv valve as it was supposed to be.. Take 1 hose from your catch can and attach that to the breather port on your valve cover, then just run the other hose to wherever. Leave it open to the air. NO PART of this setup will be connected to any part of your pcv system other than the valve cover breather port. You'll see lots of smoke under multiple conditions otherwise.

 

So your saying run the valve cover port to one of the IN ports on the catch can and put the hose from the pcv to the other IN port on the catch can and leave the OUT port to breathe to atmosphere, do not connect the vacuum from the intake to the OUT port on the catch can? remember its a 3 port catch can, 2 IN ports and one OUT

 

No sir.. 3 hoses on catch can? OK. Connect one "in" to the valve cover breather port. Leave one "out" vented to atmosphere, and just cap the other "out". Leave your stock pcv valve where it is located as stock.

 

Ye but the problem why I got this catch can was that the stock pcv system was sending oil in my intake and the trottle body would get dirty, so dats why I put the hose from the pcv system to the catch can, but I didn't connect back the intake vacuum to it

 

I'll have to see how your PCV system is routed. Mine **may** be different. But.. Hose from intake manifold to pcv valve? Pcv valve inserted into another hose that goes to black box on back of the block?

 

Would it cause any problems to keep this vacuum blocked off?

 

From factory pcv to catch can

 

Yes like the factory b16 pvc system

This is how it was originally

 

Does the pcv system need a vacuum source to work or does it work jus d same if u jus leave the hose to vent?

 

OK so, I left my pcv components alone.. The valve can still take vacuum from the intake manifold, and the black box left intact. You're just hooking up 1 hose, to the valve cover breather port.
