Oil Catch Can Install?

[b-morr]

I have this one http://www.extremepsi.com/store/cust...cat=731&page=1

I was wondering, do I just connect the breather hose from the valve cover to one of the top nipples on the can, then my hose to my intake to the bottom side nipple. And then plug the other top nipple on the can and I'm good to go? I'm not eliminating my PCV.

Thanks,
Brian

You need to check your link. It doesn't work. The way your wanting to hook it up, sounds like you would need two catchcans to properly set it up. However, the easiest way that most people do it, is one from the side, to the catchcan, and one from the rear pcv to the catchcan.

I don't see how 2 catch cans would make sense..

 

[LTUDSM]

ok ,the proper way to setup this catchcan is that:

take out your PCV vallve,and add the niple in that place,where PCV valve used to be. (i used one from my old Greddy type-s bov).Then ,run the line from that nipple to Catch can.From another catchcan's nipple ,run a hose to the intake manifold,and add the PCV valve in that hose.Then install the Breather filter on your other valve cover nipple.

NO.

Keeping the PCV valve in the stock location and adding a check valve between the catch can and the intake manifold would be the proper way. Adding a second catch can between the valve cover breather and the intake pipe would be the proper way to hook up a second one.

Follow this diagram whether you are doing one, or both.

In a simpler manner of speaking (since you are keeping your PCV stock and only have 1 VC breather), how you described it in your original post will work just fine, provided you make sure that oil doesn't come out of the bottom nipple when it starts accumulating.

good info...any bad affects from elimanating the PVC?

 

[Defiant]

No, any plastic pipe you can be elimanating is good.

Oh christ.

Hopefully you don't have any PVC in your car (although I've seen a PVC intake pipe or two in my time).

The PCV serves to:
1. Circulate fumes and crap out of your crankcase when in vacuum
2. Seal the crankcase from the intake manifold when you are in boost so it doesn't pressurize.

Keep it, along with the your VC breather for proper function. It's suggested, however, that you put a catchcan in between your VC breather and intake so oil doesn't get in, and some sort of checkvalve at the PCV since the "ball bearing in a tube" concept doesn't really do that great.

I have one catch can, so can i just install it to pcv to catch can and catch can with check valve to intake. That will keep that oil and sludge out right? Then just put a filter on the vc breather nipple.

 

[djalogik]

those little plastic inline fuel filter work great too; especially with space..

Yes

Then just put a filter on the vc breather nipple.

No. You want to attach another catch can between the VC breather nipple and intake pipe. This will let your intake pull air out and ensure proper circulation. The function is to protect your oil from contamination from fumes and blowby.

I am using a $10 air compressor filter as a catch can. It looks nice and works great.

I thought installing a catch can doesnt involve using the PCV?????

Cant you just install it using the left VC nipple to intake pipe?????

Correct. However, the topic here also includes a second catchcan between the PCV and the intake manifold. Most PCVs don't work like they should (a manufacturing defect) so blowby can go through it and enter your intake manifold. The solution is another catchcan (although less critical than the VC one) and a checkvalve so it doesn't build any pressure under boost.

 

[jm1080]

So you can run it the method I just posted? But your saying that its better to run 2 as in the instructions stated above? How come I rarely see anyone with 2? Right now Im not running a catch can, but in the future I plan to and Im not seeing any oil, sludge or anything in my intake as of now.

 

[No_Skillz]

Yes, having a catchcan connected to the VC and intake is the correct method.

The catchcan at the PCV is less critical, like I said.

Just to interject my opinion and setup on this topic. I run a catch can setup in my car and this is how I have it setup. I have never encountered an issue with it in 2 years of having this way. Here is a picture of it....

The hose on the right of the catch can comes from the crank case and the hose on the left goes to the air intake pipe. It is a simple as that for me and it works. Now I have no experience with a 2 catch can setup and really have never seen anyone run one to be honset with you. Just seeing if I can add to the discussion here was all. I hope it helps.

 

[Novice]

So yeah, About to do this my car. My intake tube has a lot of oil inside it. Do you have to empty the excess oil from the catch can as routine maintenance?

I empty mine (if there is any in there) before every event I race as part of my routine maintenance. But my maintenance is obviously different than yours. On the Catch Can I have, there is a clear tube that you can how much oil is in there. Just monitor that tube and empty when needed.

 

[No_Skillz]

I like to use the compressor filter because it's made of glass. You can easily see how much oil you have and empty it when necessary.

Obviously if you let it get full, it will end up sucking the oil into the intake.

So you are running your pcv back to your intake mani? The thing I'm currently having a problem with is I have 3 ports on my catch can. I want to do my setup the same as you, but I don't know which ports to use. I have 2 on top, and one on the bottom side.

b-morr - I could be mistaken, but I believe the 3rd port on yours, the one on the bottom side is a drain hole. Or supposed to be used as one. Did it not come with some sort of plug to go in that one? If not, I would recomend some type of plug in that one and use it as a drain hole. All you need to use are the top 2 inlets on the catch can.

As I said above, I have mine setup starting at the cranke case > going into the catch can utilizing the top right inlet > top left intlet goes out to the air intake pipe. The picture I posted just does not show it actually going to the air intake pipe. But that is where the top left hose is going to out of the catch can. I hope this helps

 

[doggo]

... so blowby can go through it and enter your intake manifold. The solution is ...

Adding a second, in-line check valve (like from US Plastics), will pretty much eliminate the need for a second catch can between the PCV and the intake mani.

This has all been covered before in other old threads. Use search, people.

It might be, and no, no plug. It's out in my garage right now so I'll check in the morning but I believe that there was another thing on the very bottom that I think is a drain plug. I'll check and get back in the morning.
