That's my suspicion. I think the right way to fix this problem is to
remove the front cover, seal a new gasket with Hylomar (instead of
Silicone), then torque the cover and cam plate right away.
If you don't want to go through that again, I suppose you could clean
the threads of the cam-retaining bolts and the block VERY WELL with brakleen
or laquer thinner, then use Loctite 271 (or superceeded equivalent) to hold
them in place. While in theory the cam should see axial force only from the
oil pump drive gear, I'd still be a little squeamish about not preloading the
cam retaining plate at all.
