Thanks for all the replies,

I took the check valve out to check the vacuum (was good) then I did have a little bit of brake fluid come out of the hole on the booster. Wiped it off and it never showed again.

I have a basic 350 with bolt ons no internals. So no cam issues.

I will try the master cylinder, as nothing is wet.

I will post my results later this week, thanks guys!
