I want to minimize the galling damage to an IO-540 Lycoming engine that has been sitting in a hangar for three years without having been run.
I had an airboat with an automotive engine that would sit idle for 9 months until the next duck hunting season and I applied a pre-start regimen before firing it up and the engine always maintained its compression and worked flawlessly,
I was wondering if it would be of value to do the same to the Lycoming.
The regimen I use for the auto engine is as follows:
A -- Drain the oil and remove the filter - then replace them both.
B -- Pre-lube the engine by forcing oil into the engine through the block tap-off to the oil pressure gage.
C -- Remove the spark plugs and spray WD-40 into the cylinders and let it set for a while.
D With the spark plugs removed rock the crankshaft (by turning the prop) in both directions starting with small movements and increasing the arc until a full rotation is made while continuing to spray in the WD-40.
E -- With the spark plugs still out, fuel restricted and the ignition disabled crank the starter until pressure registers on the oil pressure gauge.
F -- Replace the spark plugs and fire it up.
QUESTIONS:
1. Will the above regimen do a good job or is there a better way?
2. If memory serves, I once forced oil into a rebuilt Continental 0-200 through the crankcase tap off to the oil pressure gauge. Would this be applicable to the Lycoming engine as well?
