You mean the passenger side, right? I once put the wrong sized filter on and ended up with a good sized puddle.
I have a mechanical oil pressure gauge with a copper tube going to the filter housing. Do you have one, too? Did you break it? (Done that, too.)
If not, check the filter again. That’s sure what it sounds like.
