Hi,
I have a 6CTA8.3-M3. My oil analysis came back showing high levels of sodium, silicone and potassium. The report says to check for source of coolant leak and repair. It also says inspection for source of wear may be warranted at this time.
The oil analysis is attached.
My questions are:
Are these levels high enough to require immediate action?
The Cummins troubleshooting and repair manual lists the oil cooler as the most likely cause. Is this a fairly straightforward part to replace? Looks to be from what I can see in the manual but I’ve never replaced one and would appreciate your thoughts.
Thanks for your help!
Ron
