For months now I’ve been chasing down an oil leak….every flight I get a light film of oil on the front gear doors, but haven’t used a quart of oil in 9 hours….every chance I get, I’ve been removing the cowling and tightening up and looking for oil leaks (all with the supervision of my IA). AIs point was it’s an airplane, you will have oil leaks… And every trip still yields oil. Finally today I discovered oil on the oil temperature sensor…see pic…the only way I could photograph it (because of the odd access is with my borescope…)
then I removed it…gasket apparently didn’t crush correctly…
that sensor was installed when we installed the engine Lycomming factory rebuilt in sept 2018…so we went over 4 years before it stated to leak…
also, the oil did not appear to track down on the engine where the sensor is mounted
hopefully I found the real culprit…as you can see my nose gear is well lubricate and will be forever rust free!
