I'm going to buy a zero time engine that has been sitting for years. What do I need to take off of it and check?
Search for the Lycoming Service Instruction 1481B, preservation of Lycoming factory engines. This is for engines in Lycoming factory packaging and as your engine is a zero time engine it was rebuilt by the factory or an authorized repair station designated by Lycoming to rebuild and "zero" the time.
There are specific inspections required every sixty days, but rather than try to repeat the entire SI here it would be easier to download it and read it yourself.
If the engine has not been preserved for years you may want to have it disassembled and throughly inspected.
But it won't really help in the case of an engine sitting for years under someone else's control...
But it will give him an idea of how it should have been preserved and inspected. With that knowledge he can formulate a plan to correctly inspect the engine and return it to service.
