This is what i came up with for the vacuum-pump to valve cover connection and baffle. No welding, no bolts through valve covers, can be removed.

Using Moroso pn# 22635 which is a hollow nut with holes around perimeter. Used a 90 degree bulkhead fitting which threads into the Moroso "breather nut." Drilled and tapped this nut and fastened cut out piece of aluminum.

2- notice the aluminum plate extends to middle,
making end opening in-between rocker sets. Used a couple 2x4 pieces and a vice for a metal break.

nice work!
it looks very restrictive, will pump get enough air?

Looks good

You only need air not oil....... it does not look air tight to me.

nice work

the alum plate is not as tight as it looks in the pic... there's aprrox .150 gap all the way around.

the moroso pn# 22635is for the breather nut, straight #12 fitting, rubber o-rings and washer.

I do believe they sell this as part of a comprehensive vac-pump kit- but, can be purchased on its own.

Need the baffling? I am not sure but, after reading several posts recently concerning amount of oil being sucked out of motor- i figured it could only help. I have not run a vacuum pump before, so this will be somewhat of a test.

it would be good if you had putting the fitting between the rockers where the holdowns are ,that way you will not get alot of oil splashed out at the fitting

We mounted one on a friends car in the front end of the drivers side VC.

We welded a bung on the front side for the pump fitting, and on the inside, made a simple baffle that we welded to the inside of the VC to prevent excess oil from getting in the line.

Works awesome

I use the REHER-MORRISON valve to control pressure because it sends cool air directly into the pump.

I think STAR products makes that regulator because I have one just like it I used for a couple races on the shelf in the garage.

Would sell it for a good price if someone needs it and they are TRICK....

Here is my own version....

Looks great!

long time no see Nelson,are you building another car for yourself?

I prefer the Star baffle, I tried all the others and it was the only one that worked for me. But a B1 heads leave a LOT of oil up top so it seems more critical than with Indy heads. I know I have never had an issue with any Indy head breather set up, provided it pulls from the top of the cover I also recommend the Star regulator, I use one with my Moroso enchanced 4 vane.
