Were the oil samples take properly? Engine warmed and run for some time? Sample taken from mid level just after shut down? Care taken not to get crud on the sampling tube tips etc etc? It may be worth double checking the procedure then sending out another sample of the same oil. I have been doing oil sampling for 25 years on aircraft and can say that how the sample is taken can drastically change the reading. So much so that if we get a sample back with odd readings we always do a resample for verification prior to making any real assessments or oil changes or parts changes. Cant tell you how many have initially had a strange result only to resample paying close attention to sampling protocol and then getting a normal reading. On the other hand we have also pulled engines off the pylon solely on sampling as well.
