Guest Posted December 8, 2020 Report Share Posted December 8, 2020 We’ve just pickled an IO-360A3B6D in a J model for a customer who will be out of the country for more than a year. We’ve soaked the cylinders with several coats of LPS#3, removed the magneto and installed a cover plate and gasket, then filled the entire engine with oil until it spit out the breather. 6- 3/4 gallons of oil!

Clarence Is there any way, given the time is over a year, that the oil can make its way past the rings, fill the cylinders, and then make its way down the exhaust and into the intake through open valves? Or, is that just crazy talk? Quote Link to comment Share on other sites More sharing options...

corn_flake Posted December 9, 2020 Report Share Posted December 9, 2020 I'm curious about what MikeOH asked as well. Aircraft engines isn't known for their tight tolerance. Also, what kind of oil did you use? Will Marvel Mystery oil work? Quote Link to comment Share on other sites More sharing options...

cwaters Posted December 11, 2020 Report Share Posted December 11, 2020 Hey sorry for the newbie question here but is the point of submerging in oil just to prevent corrosion or is there any other reason, if its just to keep water from the metal why not just use the cheap automotive oil? Also how do you seal the tailpipe and intake filter? - again newbie here. Quote Link to comment Share on other sites More sharing options...
PT20J Posted December 11, 2020 Report Share Posted December 11, 2020 What about the fuel servo? My factory rebuilt came with a bunch of preservative oil in the servo. Skip EDIT: Added Precision Airmotive preservation info. Quote Link to comment Share on other sites More sharing options...

My hope is that if the inside of the engine is completely full of oil, the cam and lifters and portions of the cylinders in the crankcase can’t corrode. When I drain the oil from the engine later, I won’t have to worry about any residual non aviation oil left behind. Clarence Quote Link to comment Share on other sites More sharing options...
aviatoreb Posted December 12, 2020 Report Share Posted December 12, 2020 How much parts and labor to do that? is there any concern w instruments? the ultimate would be then to chill the whole airplane maybe to say -15C to slow chemical processes.
