What looks like oil in my rad???

Hey guys hoping someone can help me here,
I have an 89 b2200 and I pulled the rad cap off and its milky so I pulled the bottom hose off and stuck a hose in it for like 20 mins till all the milky water was flushed, reconnected the hose and ran my truck for a bit and same thing, however there is no water in my not a sign of it at all... Any Ideas as what could be the problem???

sweet ill try that, do you know the torque specs?

60-64lbs i belive we did mine to 70

my truck did the exacr same thing as yours it was a cracked head ...when you redo the gasket have the head pressure checked and resurfaced

are you shure the its oil bc i have had some engines do the same but its just the anitfreeze kinda breaking down and get kinda like white milk globs.

hey man just to let you know i was geting oil in my rad and came to find out where the head bolts go threw into the block they have hair line cracks so just a little info thought you might would want to know.

hahaha Found out it was a cracked head..... Sold It..... New project time
