Actually… almost lolSee post #40 Think I got it
I think this one would be less of a problem since it has to get past two rings instead of just one.
The one that I see is a problem is this one…
air just has to move around one o-o ring and then leak out around the seam of the block and the lower section of the frame

Don't understand what arrow is pointing at ?
But yes, pressure within throat during shot can very much travel around body of seat and I.D. of housing going out the hole that factory "Is Not" blanking/sealing where transfer path is drilled in manifold during manufacturing.
Perhaps tap the lower hole if enough meat is there w/o interfering with seat, or having housing fit frame and screw in a plug ( Say a shallow 1/8-27 NPT )

lol my poor attempted an arrow was pointing at the daylight through the bottom. Indicating that’s the hole that is possibly the culprit to my wowe’s
Wouldn’t a BSP thread do a better job of Sealing without having to use any kind of Teflon tape?
Or would that be the wrong type of application for a BSP thread?

inside 10 min on bench we have a fix ...
For you self doers ...
If you have a lathe ? .... super simple part.
O.D. is .348"
O-ring groove @ .080" wide by @ .060" deep
O-ring an SAE #011 buna
OAL @ .170"

You had reminded me of seeing noting this potential issue a couple years ago tho forgot all about it never noting an air leak .... Tho was not chasing one either.
Makes no sense factory did not address this ? As air path integrity is reliant on the near zero/zero fit of seat into housing in not having air pass around the seat ( Between o-rings ) and exit out this hole.

soooo much better than epoxy lol
I can pay you

Thanks for the measurements
I will knock one up, it's a bit of a strange one as MSR Workshop seems to have discovered this problem, yet as I seem to remember you also made up and used filler ports for the valve seat to barrel seals which in theory should increase the risk of leakage around the valve seat between the two drillings due to the extra resistance.Upvote 0
