Hi and welcome to the forum.

I'm sure some of our Cummins experts will be along soon but it sure doesn't sound good.

Best of luck

sorry to hear that... mixing oil with coolant - either oil has coolant (milky oil) or coolant has oil (trace of oil floating) - is surely no good. i wish you had come here prior to the purchase as fellow rvers would have told you how important a PPI would be.

for now, do not start engine. search yelp.com with key words "diesel engine repair" and your zipcode to get a trusted mechanic and call him. if you need to drive your rig to his shop, make sure change oil first (any brand 15w40 oil will be fine, such as walmart supertech brand. it's just a temp solution to prevent from further cylinder damage. after mechanic fixes your engine, he will change oil/filter anyway). good luck.

YOu might look online. I am not sure your oil cooler has water running through it. I am sure some of the cummins experts will be on here to make sure but are you sure your oil cooler is not just a mini radiator that has air running across it instead of water ?

Check to confirm you have an oil cooler, and if you do is it in the radiator. This is much more common in smaller applications. For example, I do not have an oil cooler in my radiator. If you do not, then the issue is in the engine (most likely) and could be as cheap as a head gasket and as expensive as the block cracked internally. Perhaps a head in between.

This could get very expensive very fast is what I am saying!

You do have a oil cooler. It's mounted on the side of the block and it's located just in front of the oil filter. They are an issue with the isc motor but when they go most of the time you will have oil in the coolant most of the time because the oil presure is higher than coolant presure while running. Yes you can get water in your oil as well because when you turn off the motor the presure on your coolant system is going to be around 15 psi or so, but you should have oil in your coolant tank if it's the oil cooler. How much water is in the oil?
