My 914 has been installed for some time now (over a year) on the aircraft in the
garage. It has not been started yet however. Last weekend I removed the
sparkplugs and rotated the prop through to bring up the oil pressure and get
oil pumping through the engine. Received good pressure and continued for about
2 minutes by hand.
Went out to the garage today and found a puddle of oil under the aircraft.
Removed
the lower cowl and found the air filter saturated and dripping with oil.
Removed filter and observed turbo intake impeller area with mucho oil. My
initial assumption on this is that by turning the engine by hand I am
pressurizing
the turbo sump. But since there are no exhaust gasses driving the
wheel there is no scavenging occurring and the oil is just filling up the
turbo housing. I am assuming that at the temperature the turbo runs at is that
it does not have conventional oil seals that could have been damaged. Do
I need to investigate the matter further or are my assumptions correct? Input
---From the turboheads much appreciated. Thanks
