Another update. I actually found out that it seems to do this anytime it's cold. It doesn't matter if it sits days or 4 or 5 hours on a really cold day. When it's cold it makes this noise and it does it for a few seconds until the oil pressure comes up. As soon as the oil pressure needle gets up to about half way the noise goes away. Any idea's? It drives fine and I've been driving it.

 

probably need a new oil pump

 

are you using the right oil weight? you might need a lighter oil if its cold

 

Yes I'm using the correct weight oil.
