I get milky oil on the bottom of both valve covers. There is nothing in the pan and nothing in valley
So I have heard that this may be OK but usually milky oil if a concern. Prochargered wedge. Joe Gibbs 20 W 50 oil
It was bad last winter as I started the car and moved it outside and inside the shop numerous times. The car was not driven in the winter (canada) so it never got driven or have the oil warm.
I was told that to get the engine warm and boil off some moisture.
I took it for a good drive today with my wife and when I got home I checked and still white Temp of engine between 180-200 and oil temp at 180 at the end of the day.
I have 2 lines from the valve covers into a separator
Any thoughts?

I think you just need some better crankcase ventilation, a supercharged engine pulls in a lot of air, air has moisture, all engines have some blowby, which contains moisture. First thing to check is how much blowby do you have? A cylinder leak test, and if you have access to one they make blowby testers as well. You can build one. https://www.sbmar.com/articles/measuring-blow-by-the-real-test-for-internal-engine-condition/I have seen many supercharged engines that run good, but had excessive blowby and slobbered a little.

Thanks for the info. I have been driving it longer and rad temps at 190-200 but oil only goes to 160-170 max.
I took the valve cover off and it only has a smaller portion on milky oil by the filler and none by the evac tube.
I have only used 94 pump gas. which can contain up to 10% ethanol
I definately see that I need to drive it if I am going to start it. Not starting to just move it out of the shop

Like a 12 Volt? Plumbed In? The vacuum is connected to 1 side of the valve cover after a run or getting warmed up and draws air from 1 side of the engine to the other not mounted in the car.I saw a 120v shop vac very small on Bill Lutz car in the pits and there was a few others.
