I knew going into this I would need to catch up on deferred maintenance. I pulled oil samples from each engine and sent them out to Blackstone and just got the results back today.
The Starboard side report isn't great but I think it should be ok and I have fixed any of the offending bolt on parts that have contributed to some of the questionable numbers (oil coolers, risers). I'm not sure what to do about the port engine. The compression numbers were all within GM spec which is 20% I was around 12% at the widest range. I just ordered a better borescope and can do a visual inspection of the cylinder walls which was Blackstone's suggestion. My scan tool arrive and the total hours on the port engine is 236, no codes and no excessive RPM history.
If a visual of the cylinders looks ok, would you "ignore" the oil analysis and keep going or dig deeper? Sure wish you could do oil analysis real time.
