oil in water

[garyeco]

Need some input. Got a 94.5 f-250 PS Manual 345000 mi. Started to develop a little miss.I use approx. 2qts. oil between changes,no leaks of significance. I looked in the radiator and noticed a little oil on top, in the overflow tank was approx. a half inch of chocolate milk. What to think, oil cooler, head, cracked cylinder? As for the miss, I'll be checking the valve cover wiring,but this oil thing has got me a little worried. Any body else run into this problem?

Normally it's just failed/old o-rings in the cooler. Not a tough job but depending on where you get the kit can be a little pricey.

oil cooler o-rings or cooler itself for the oil in coolant

Thanks guys for the reply. I took out the oil cooler today and found a rip in the block heater side gasket. Replaced both end gaskets as well as o-rings. Driver-side front valve cover injector+glow plug harness connector was melted. Nothing money can't fix! Oh well thanks again for the input!
