Milky oil leaking from oil pressure sending unit

Hello,

Milky oil is a sign of a blown head gasket. Is the oil that color when you check it on the dipstick?
The best plan of action would be to test and see if indeed that is what has happened.
Take a look at this guide:

Let me know what you find.

I have attached the head gasket replacement procedure for your reference.

Thank you.
