Tom:

That is not uncommon.  I have seen oil filter canisters burst because
the cold dino oil did not want to move causing the pressure to build to
the bursting point.  This is where you get a lot of startup wear.  Oil
isn't getting to the parts.  High oil pressure means no oil flow.   Not
a good thing.
