I know with the Supercharger valve it was tight but nothing a little dow33 and thinner cupseal o-rings couldn't fix.
Just wondering is the valve body sliding in at all?
If it is you should be able to use the valve tool to apply a little pressure to get the valve in.
If it not sliding in at all, you might have other issues.
P.S. Do you have a second AKA valve to test with?
