I wanted to update you all on my latest interesting annual on N12AY.
I had a top overhaul done on my old 914 due to my over speed. Kerry Yunk at Lockwood did a great job replacing my intake valves and cleaning up the seats, cylinders and such. I also had the gearbox done as it was nearing 500 hours.
Initial pre annual test flight after the rebuild had some pesky oil leaks, overheating and the typical maladies of a 914 that has sat for months due to other priorities.
I finished my annual but after many engine runs the coolant leaks were just a loose hose clamp or two venting pressure. The oil drips were common from the plenum, and the only surprises were my magnetic plug (new style) threads are a bit loose and to seal it properly, I used some Loctite 515 to seal the threads. I failed to properly seat my oil screen in the tank after cleaning which spit some oil off the can.
The turbo seemed to be leaking oil. I worried about all the areas that could be wrong or failing. I looked, ran the engine, and fussed over the engine. The clamp on the 2 inch turbo to plenum line was poorly fitted after maintenance and I missed it. The old adage it is always the last thing you checked was proved right again.
Thankfully all seems dry again.
Attached is a paper I did on N12AY putting on some drip cans I will keep with my aircraft documentation. I copied Ron Paragoris's oil separator idea but on a smaller scale to test. So far so good, and I'm a happy non greasy maintainer. Now it's time to be a happy flier of a clean aircraft.
Best Regards,
