How did the lab’ determine that the contaminant was salt water? I’m not certain the standard tests would determine that (could be wrong)
- Water by Crackle measures % of water volume present in oil by using a hot plate.
- Water by Karl Fischer measures water by titration and is reported in either ppm (parts per million) or % by volume.

Was the engine emitting any white smoke, especially /w a sweet odour (a sign of possibly blown head gasket)?

Is your engine raw (salt) water cooled, or does it have an intercooler (heat exchanger)?

If equipped with heat exchanger, was there any sign of low coolant (after running)? If additional fluid is repeatedly needed to maintain the proper coolant level, then a coolant leak is likely.
