my resevoir tank has OIL and water in it...WTF?!?!?

 

WTF! WTF! WTF!

 

I had this happen to me when I didn't change the coolant enough. Anti-freeze has oil in it that breaks down and separates. Flush the system and replace with 50/50 mixture and you should be ok. I wouldn't be worried unless the overflow tank is overflowing and your buzzer is going off.

 

Yea it happened to me and i just so happened to have a damn hole through my block

 

damn a hole in your block...that sux

 

it looks like motor oil. straight BROWN SMELLY OIL. oh and my car smokes from behind the intake manifold when i run it for mor then 5-10 minutes.

 

Sounds like the equivilent of a cracked head. Maybe one of your coolant or oil pockets isn't quite right? NEW HOUSINGS!
