Hardin do you have part# on the evac fiting from vibrant and the hose
I was just going to make one for my setup. It's just a nipple with an angle cut in it. I do have this though to go with it

My current engine is built to loose and has alot of blow by, the check valve was too restrictive. They are supposed to only be protection from back fires in gas jobs. My vibrant setup will pull a lighter flame into them from a good 3-4" away at idle. Was going to do some test since I rigged up a crankcase pressure/vac gauge but never got around to it.

The Vibrant setup goes a step further than a nipple welded in on a 45°. You weld a bung on at 45° angle than the Evac deal threads I to and has a nipple that sticks down in the exhaust with a small venturi hole in it. Works awesome so far and they are only like $25

I have 2 seperate hoses both run down to the passenger frame rail. Just figure less restrictions with 2 seperate hoses. And i didn't have a t anyway.

Kyle I am going to put the Vibrant setup on my truck but wanted your feedback first. Did it solve your dipstick issue?

how do you connect to the valve covers with a system like harbin-22's ? do you use the factory hole but remove the diaphragm and spring?

You can convert it to -10 AN. Idk about Kyle, but I have SoCal covers with 1/2 npt ports.

Steve I have not had a problem since doing these. I have a crank case pressure gauge rigged up and don't see anymore than 1-2psi positive at full boost

I just have one of alligators regular 5/8 nipples on each valve cover and put the -10 on with hose clamps. I did take the diaphragms out of the valve covers also.

Perfect that's what I was hoping to hear. Parts are on order.

So you removed Check valves in valve covers, ran line to catch can then through the one way diaphragm to exhaust?

Never mind I didn't read it all. I order the moroso Check valve also and it was to restrictive. I saw the pic on here and for some reason order it instead of the vibrant setup. I'll be swapping it.

Out and about
Same setup here, I had fittings with baffles welded to the valve covers to stop the drool. Couldn't get the pipe thread to would seal. Also have the evac fittings like Kyle but haven't had a chance to run it with them yet, got the idea from him.
