Hey guys. We've got an 87 250 with the 6.9L. And it's got water in the oil. I have a strong feeling that the head gasket(s) are toasted. When I checked out the motor to see if there's any visible signs I came up with nothing it doesn't look like there's any visible oil/coolant leaks. Is there anythng else besides the head gasket that could possibly let water in the oil?

It just attaches to the rad neck just like a rad cap and you pump it up. Coolant in the oil has several places to enter..... water pump bolts or front engine cover behind the water pump. Head gaskets as stated, valley pan sealing surface to head... oil cooler itself as well as the orings.

Is the oil green slime yet.......
