Hey, Dave,
I have an IO360 200 hp -CIC- Lycoming engine with only 83 hours total with good compression but the last time it was flying was 20 years ago. and has set in my warm dry garage for the last 4 yrs. It was part of an estate sale.
It was an unfinished Acro Sport One project I purchased. The project was in good shape when I bought it. I had to buy the project to get the engine. The engine has a good log book that went with the project. I since have sold the rest of the project. Now I want to know , what is the best way to determine how good a shape the engine is with out dismantling it.?
This is the last major step to finishing my Starduster . Your words of wisdom will be greatly appreciated, Tom
Tom there is no real way to tell, without at least pulling one cylinder, and try to determine the internal condition. You have about a 50/50 chance of it being serviceable. The odds go up in it has been in dry humidity free storage sealed up with dryer plugs. Like in Arizona, by contrast if it has been in damp humid parts of the county and no effort was taken to pickle it then the odds go down.
The cam and lifters on the lycoming engines are usually suspect, as well as cylinders, especially if they are steel. I do not recall what lycomings position is if the engine sets for any appreciable length of time in that they recommend it be overhauled. But if you plan on flying it, the only real way to know would be to disassemble it and check all of the parts, on a certified engine that means many would need to be replaced.
A bore scope could give some indication for the cylinders, but the cam and lifters without splitting the case, or possibly by pulling one cylinder as they are the big item, and there are so many variables? Dave
