My engine was started last week after 5 months. Oil mist was sprayed into the engine for a considerable time and the RH was 6% from my DIY dehydrator and I had dehydrator plugs fitted also. I’ll report back after the next 25 h oil change.
I am interested in how @kwlf is getting on with the oil filling method as it is very simple.
If your engine has been in storage for some time simply filling it with normal engine oil, blocking the breather holes and turning it upside down before you fit it into the aircraft should keep enough oil on the cam provided you start the engine within a week or so.
