Need some help !!!!!!!!!!!!!!!!!!!!!!!!!

Doh!
Well you better check what's in the oilpan,(crack the drainplug)
Oil in the cooling system?Hmmmm. In order for this to occur, the oil would have to be at a higher pressure than the cooling system.Since the cap is usually controlling the pressure at 13 to 17 psi, there are only two other sources of higher pressure in the engine; 1) is the oiling system and 2) is cylinder pressure.
If there is no coolant in the oilpan, and the cooling system holds pressure, then IDK. Is there any chance that that is something other than oil?Is the same stuff in the top of the rad?, or in the overflow tank?
BTW; how's it run?
