“During an annual inspection, ferrous metal flakes were found in the oil filter,” states the submitter. “Several pieces (were also) found in the finger strainer. (All of these pieces) were sent to Textron Lycoming for analysis. It was reported by them that the ferrous metal came from the camshaft and tappet bodies. The engine was removed for overhaul. Time since overhaul is 2,092.9 hours. The camshaft was replaced at 1,164.4 hours since overhaul.

Total time on the Camshaft is 928.5. The average oil change interval since overhaul is 91 hours. (I) recommend the 50 hour oil change interval recommended by Textron Lycoming be strictly adhered to.” (The camshaft P/N LW-18837 returns five additional entries from SDRS data.)

Part Total Time: 928.5 hours.
