Just got what looks like a bad report from consecutive oil analysis. 45 hours on oil. they told me to "Give the engine a good, hard look.). Engine hours, 501 SMOH
Aluminum up from 19 to 33 (26 is normal)
Chromium up from 8 to 13 (11 is normal)
Iron up from 62 to 99 (81 is normal)
Copper up from 20 to 24 (22 os normal)
Lead up from 5025 to 7461 (6243 is normal)
Tin up from 2 to 3 (3 is normal)
Molybdenum up from 2 from 3 (3 is normal)
Silicon up from 5 to 7 (6 is normal)
Phosphorus up from 904 to 1033 (904 is normal)
Interesting that in the past 45 hours, (I got carried away the last couple and went over 40, I normally change oil and filter every 30-35 hours.) EVERY reading was less than the normal range for the T4B5D and now EVERY one is up, some significantly. Mechanic found oil in #4 at annual with borescope.
Diagnosis Please?
