Crankcase Vent Solved

[jpbrazill]

Here's Hal's billet oil cap, and -10 line to a catch can.

Does this setup seem to work pretty good?

 

[black_gst]

seems like a great idea... what are the real world results?

 

[dsmfa9nutter]

Seems excessive. Why not just weld an bungs onto the side of the cover?

Good looking cap, but I see a few potential problems with that setup in general.

This setup works just fine. The cap is baffled, so very little oil makes it into the can.

Is the stock VC breather port just left open as shown in the 2nd pic, or do you have it running to somewhere?

Is the PCV valve bypassed? Can't really tell from the pics.

Interesting concept, would love to see some tests done.

Yeah, the PCV is bypassed. I am pulling the breather barb out, tapping for 1/8" NPT and running an additional -4 line to the catch can. Its just not done yet.

Now stop running it to atmos, and put a vacuum source on that catch can (from intake pipe).

Looks great J.P.! It won't be long and I should have this setup on mine as well.

I'll be home in another week so I can start pulling off the old intercooler and intake manifold! Thanks for the billet catch can BTW. I have to install that as well with all the other parts that are laying around.

The vacuum source from the intake is an interesting idea. Any other thoughts on this?

They just used the same one on horsepower tv. Looks like a nice set up

 

[jpbrazill]

I could use the intake as a vacuum source, but I have been floating the idea of using the exhaust instead. Next up, will be using a -4 line to drain the catch can back to the block.

I wouldn't. That catch can catches water vapor and gas vapor along with the oil. It cools and condenses in the catch can. Do you really want to put that back into your oil?

The stock setup puts it back into the intake so that it eventually goes out the exhaust instead. Eventually...

is it safe to vent to the atmosphere with the stock maf? Wont that cause unmetered air to enter and exit?

 

[turboglenn]

That's a sweet looking setup,you machine taht yourself?

He has the PCV valve bypasses, so no unmetered air is getting into the motor, nor is any metered air getting out. This system is essentially opens up the ports to allow the crankcase pressure to exit less restricted.

Where can I get an oil cap like this?
