Did you torque all the bolts at once?  If so, you may want to undo and
re-torque them.

It is actually best to tourque the bolts to half specs (ie set your wrench
to 24lb), and follow the proper pattern-- then set your wrench up to 48lb
and finish them up (also following the pattern).

It will set the bolts better.

good luck,

PS don't overdo the bolts, breaking one is worse than having it leak!
