Normal as said.
If you read a bit you will see most of us loosen all three screws, but loosen only 1 enough to control the gusher, it works pretty good. Then remove them all and change the filter out.
Make sure you get the OLD filters gasket out. Also make sure you get the NEW filter on tight enough, not gorilla balls to the walls tight, but tight.
Make sure your new (or old) o-ring for the cover is clean along with both matting surfaces.
And as pointed out, gentle on the screws you are only compressing that o-rings thickness.
Now if you liked that oil draining, wait until you get to the tranny draining :histerica
