All knowing FOT

Attached is a video of my Type A OD unit ready to bolt up to the transmission. 
I decided to do a pressure test with 120psi of compressed air plumbed into the 
operating vale port. 

The engagement seems to work well when I move the operating lever. But I am 
concerned about the amount of air that can be heard leaking. I believe it is 
going past the relief valve. Is this abnormal amount of leaking?

I noticed upon tear down that the nonreturn valve had a 1/4" ball instead of 
the 5/16" this unit should have had. The test you see in the video is with a 
new 5/16" ball. I am sure on a previous rebuild someone mistakenly used the 
later style 1/4".

Just wanted opinions before I buttoned this up to the transmission for some 
bench testing. 

Thanks.
