        This has happened to me before.  Not with a Bosch filter.  Mine was due to
"pilot error" in installation.  Rubber seal ring managed to slip out of
position when inserting cannister type filter onto a '72 Mercedes.  8
quarts in the driveway.  What a mess . . .
        Since then (many years) I double check and triple check the seal rings on
any kind of filter before casually slapping it up there.  Also, never
overtighten an oil filter.  It can cause the gasket to pull away from the
filter housing and begin to bind up on itself, creating ripples, and
warping the can.  Leak city!  Could this have the culprit in your case?
