sorry guys i dont mean to offend anybody and red rattler if diabeties is that big in your family please have your sugar checked at least a couple times a year as your inline for it, its hereditary and you need to catch it quick. also to o/p dont run your engine till you find the oil in water problem because if oil can get in water then antifreeze can get in oil and it will kill your rod & main bearings along with cam bearing. is oil milky looking ?

Make sure to get the radiator and water jacket cleaned out good after you fix the oil cooler. Several daily flushes after running with a mild detergent solution will clean out the oil and prevent the inevitable overheating problems from a sludged up radiator.

this is true powdered dish washer soap and hot water (to dissolve it) try to stay avay from liquid soaps as they can tend to foam real bad

I just had the same problem with my truck. oil comming out of the radiator and overflow. do you think it could be the oil cooler or head gasket? if it is the oil cooler how much do they run and where can i find one at?

We still haven't bought an oil cooler... From my research its about 80% of the time oil cooler 20% head gasket/cracked head or block.. you could prob post in the quotes section and get a price on one...:tu:
