I agree with Orma, strip the motor. I purchased an engine that had been sitting for 4.5 years plus. When started it, the rust on the crank went through the bearings and seals, destroying the crank, rods, damaging the pistons and barrels. ----- Original Message ----- From: Orma
engine has not ran since 1982. Hello Net With an engine that has not run in the past 23 years, I would look a lot deeper then the items mentioned in the post. If the engine was pickled, it would probably be ok. If not, then the walls of the steel cylinders might have enough rust to cause it to fail at some point after the engine is back in service. I have opened several old VW engines and have always found that the crank is free of rust if the engine has had oil. On the other hand, the cylinders always had rust and the lifters were in bad shape also. The hot and cold cycles of winter and summer build up moisture as a normal cycle. Lycoming had engine failures due to this hot cold cycle allowing moisture to collect on the crank shaft and cause microscopic pitting corrosion deep enough into the crank to allow failure. The cost of opening that 23 year old case is less then $100. That seems like cheep insurance from my view point. As a professional AP/IA I would hesitate to put my name on an engine that sat that long without someone looking inside.
