Back in the fall I changed the oil on my 3116s in my 99 400DA and sent in the oil and coolant samples for both engines to CAT SOS. The starboard engine report showed a trace amount of oil in the sample and the report suggested that I contaminated the sample when taking it. So I bought a separate sampling pump and took another sample recently. It still shows a trace amount of oil in the coolant. I have no feeling for what a trace amount is. I’m sure you can easily detect a drop of oil in a swimming pool of water, so I am not sure the severity of the issue and what I should be doing here. A cursory look at the web and a discussion with Frank Webster indicate the most likely suspect could be the Oil Cooler unless I somehow contaminated the coolant myself. So I thought I would ask you and see what your thoughts were. Just because I know someone will ask, the coolant levels have not changed in the last 200 hours of operation. I did have an issue a couple years ago with a cracked hose between the radiator cap and reservoir. There is 300 hours on coolant over 3 years.
