Alright guys, couple of questions here regarding my OCC setup on my b20v.

I'm tapping my b18c1 VC. I've see pictures of where people tap it, but I can't seem to figure out where to tap exactly. I need to know due to the baffling and what not.

Secondly, I'll be using 10-AN fittings. Does anyone know of a fitting I can use to mate an -AN fitting to the VC without threading the VC ports? I also don't have access to welding.

Thanks!

 

Interested too

somewhere i read or watched a video that explained how one end of the head gets better oil flow than the other end. it seems like the end opposite of the oil pump would be a good idea. youd want it to pull air from from above the baffle though, otherwise it might suck up too much oil.

 

I'll just bite the bullet and get a couple -10an fittings welded on. JEGS has aluminum ones, I figure that will be easier to TIG over steel fittings.

Does any one know exactly where I should tap the VC?

Thanks

 

I see nobody took the time to actually search...

Practically every AN fitting maker has bulkhead fittings...

As far as placement, it pretty much doesn't matter. Some people will say this, others that, in the end as long as it doesn't allow oil to directly get slung into it, it doesn't matter. Some people even run without baffles others almost have a heart attack if you don't run them.

Completely personal preference in my opinion. Most will run on the 2 on the front and 2 on the back side of the vertical parts of the valve cover. If your system needs more than that some may use the 2 on the back of the block. After that you are beyond natural crankcase ventilation and a evacuation pump is required.

 

**** man, thank you. I knew a fitting like that existed and I looked but I couldn't figure out what they were called.

So, you're saying some people run with no baffle in their can? That's what I'm tying to decide now. Whether to spend extra for a baffle can or not. I'd obviously like to not as I found a solid ebay can:

Thank again for the guidance and help.

 

Sorry, I misread the question I guess as my answer pertains to the valve cover as to whether or not to have a baffle. With that being said, the same answer applies to the catch can itself... Most people prefer some type of baffle though. You can do this very cheap with some stainless steel wool stuffed inside a non-baffled can. Many people have done this with great success. If an issue arises like a clog you can either clean the wool or just buy a new one. The goal is to simply not allow the oil mist to escape the catch can and instead get collected inside the can. Most people don't like oil all over their engine bays or the potential fire hazard. Simple enough.

You are welcome.

 

Awesome man. Thanks again.

One last thing, with just two VC OCC porta, is it common to still run the VC vent to the intake or put a breather filter on it? I wasn't sure if I plumbed the VC back into the intake if that would stop the gasses from going into the can.

Thanks again.

 

Also, as I think about it more, I don't think those bulkhead fittings would work. As they would enter the VC too far and end up hitting (and going past) the baffling inside.

Looks like welding is my only viable option.

 

Don't put it back to the intake. The whole point of a catch can is to reduce the amount of pressure inside the crankcase but it also helps keep oil from going back into the intake.

I didn't see if you said you were turbo or not but it really depends on your power levels and piston to wall / ring gaps (aka blow-by) is set at.Two ports may be fine, but hard to say without knowing your setup.

The fittings can be cut down and the threads sanded smooth. Kind of the point of the long threaded portion. I would be more concerned with the nut coming lose inside the engine than anything. Welding will always be the preferred option. However, people have used the bolted style with success.

 

Thank you for the information, again.

I should have mentioned my setup: B20v 9.5:1 CR (stock) So 190-200whp is my assumption.

 

I never trust bulkhead fittings inside of the valve cover, if the nut falls off its going into your engine
