I noticed on the bottom of the PCV valve and inside the plastic tube that it goes into is a light brown coolant smelling residue. So it looks like the PCV is picking up coolant from somewhere however dipstick looks normal and the car runs cool. I'm thinking intake gasket.... Any thoughts?
That's not coolant - it's moisture and oil mixed. It looks like loose snot. Exactly what a PCV is supposed to suck up when the car is used for mainly city driving in cool weather and the engine guts never warm up enough to boil off all the condensation and acids which accumulate from the combustion process. You might also find the stuff on the inside of the oil filler cap.
Get outta town and take a 150 mile round trip for a margarita, come home and change the oil and filter, using the recommended oil for your engine in whatever type - dino or synthetic - that floats your boat.

Re: Antifreeze on the PCV Valve
My wifes '96 Bonneville (3800) has had that on the cap for the last 13 years I've owned it every winter. I can actually see water droplets on the underside of the cap, even if I drive it to work 40 miles at 70 MPH. I can't figure it out. It should not do that.
