got oil in the water for the third time in 18 months on my 02 ISX 530. replaced oil cooler twice and looking like time number 3. is this a weak point or do we look for something causing this?
Optional Information: Make: kenworth Model: T800 Year: 2002 Engine: ISX530
HelloWelcome!I would look closely for a cylinder liner or liner oring damaged .this will push the oil into the coolant Your coolant pressure runs from 8 to 10 psiAnd the oil runs more then that so you will find oil in the coolant before coolant in the oil But a oil sample test might show small traces of glucose in the oil.Porosity on the cylinder liner and on the firing deck is something else to check too.Let me know if i can help more!RD
