I?ve come across an engine with an 0-360 in it that has recently suffered the abrasion of the aluminum piston pin plug. It was identified by aluminum in the filter and confirmed by inspection. The engine was topped, crank and cam inspected, oil lines and cooler flushed and retuned to service. That was 12-hours ago and at that time the oil was changed, analyzed and filter inspected and they all look clean.
the question is that with that kind of failure and subsequent repairs is the engine likely to have suffered some kind of damage not yet detected and be headed quickly for overhaul or is it likely to continue on without collateral damage? This issue isn?t uncommon as there is a service bulletin or similar from Lycoming but I am not able to find reports of what ultimately happened down the road with impacted engines that were repaired.
If anyone here has experience with this issue it would be of great assistance,
