while checking by coolant levels today I noticed that the fluid in the resevoir is milky, I don't see any signs of oil in it, the fluid in the radiator is antifreeze green like it should be, I didn't see any signs of water in my oil when I changed it today either. anybody got any ideas what could be causing the fluid to turn milky.

 

It may be emulsified oil. I'd suggest flushing out the overflow reservoir with clear water (garden hose) and refilling it with a 30% mix. Keep monitoring the condition just in case. If you are getting oil in the overflow, you make have a compression leak.

 

I would suggest flushing your whole coolant system.
