Crankcase Vent Option
« on: October 26, 2015, 10:40:14 PM »
The fitting in the timing cover, where my old oil drain tube used to hook to, looks like a prime spot to hook up to a catch can/breather for additional venting under pressure. I thought I saw something about this posted on the b2600 site but cant seem to find it.
Thoughts, comments suggestions?

Gonna get a lot of splash. You want to pull from up high. Large lines, no restriction.
I would look at upsizing that fitting on your rear port and check that you PCV is functional and that the line is not collapsing.

Them stock rings may not be able to hold that cylinder pressure off anymore Eric. Turn down the boost or pull some timing.

I was just thinking that the port on the t/c is already huge and already there, why not utilize it along with an opened up rear port?

None the less, I will try it out and worst case scenario, as you said, I get excessive amount of oil in the catch can and i can make the call of weather to cap it back off or leave it open. I will post results.

Are you having a pressure issue? Why do you think you need more?

The dipstick has been blowing out every since I changed to this comp turbo 2yr ago. I am not really driving it right now cause of the weather so there is no immediate need to fix the situation i just have some extra time on my hands and figured I would get them dirty.

I have not opened up the rear port yet, i just figured if I dont need to drill the v/c I wont.

Plan for me is to weld a bung in place of the stock fitting. Thinking 14 -an should do the trick.

I got roughly 200mi drive time on it and the can is empty still. The car is down for the season but I will keep posting updates.

Eric,

Any updates on how it is working?    I'm doing the same on my current build.  Figure it is easy enough to block off if I start sucking in too much oil.

I havent had much drive time due to weather tanking here. Today is only the 2nd time getting out the old girl this year.
BUT as of today I have not seen any oil in the can and it seems to be working perfectly fine.
