Suspected failing vacuum pump & oil pressure switch - due to this-

Replaced switch (oem BMW) along with
Front cover seal to vacuum pump & the o-ring to the cylinder head. (Parts from pelican parts)

After replacement all seemed good - pump & switch were clean & dry after lengthy test drive.

Next morning - pump & switch still dry with nickel size oil on floor on front passenger side.

Car has 70k - valve cover gasket replaced @ 45k

Out of ideas here

Thanks in advance for any & all help
