Help! 4.0L Jeep XJ problem
Buddy of mine has a 96 jeep XJ Cherokee with the 4.0L I-6.
He is getting oil into the water, but no water into the oil.
My first assumption is like any other, must be a head gasket! But I don't know the 4.0 jeep engine.

Here is diagram of the oiling:

There is no pressurized oil going through the head gasket. A leak that allowed draining oil to enter the coolant via the head gasket would also allow coolant to enter the oil. Usually.
A cracked head could pass it either way.
A cracked block might be more prone to a "one way" leak.
How much oil is he getting in there? A trace or a ton?
