I sent out my first oil sample on the truck I purchased in Feb. I did an oil change when I first got it, so this oil is all "my driving" and nothing from the PO. Blackstone called and said there's coolant in the oil and lots of wear happening. The truck has been running great with the exception of rough idling at first startup in the morning, but thats mostly due to my WMO mix. Other than that she runs great. I changed out the coolant and radiator in late feb right after I bought the truck. I have not added any coolant since and as of yesterday, she's still topped off. No overheating or coolant consumption, even pulling my trailer.
So my question is, what could be the problem? I can only think of three possibilities: head gasket, oil cooler or cavitation. A head gasket I figured would have some other symptons such as overheating and coolant consumption, so I'm kinda ruling that one out (although that would be my favorite of the three so I'd have a good excuse for some ARP studs). I dont really want to think about cavitation, so I'm leaning (hoping) more towards the oil cooler needing rebuilt. What do you guys think?
Also, how can I diagnose these symptoms myself? I'd like to rule out cavitation as soon as possible since the other two I can handle in my garage.
