I purchased this cylinder assembly, aec631397, from aircraft specialties in 2009 for an IO-470d overhaul. I am in the process of overhauling engine again ts mo. On a cold compression test, the cylinder was with no exhaust or intake leaks.
The assembly is complete including piston. I have 3 remaining cylinders from the same engine, times and shape that am putting up for offer. It would be a good core for overhaul. I will include the original it is being sold as removed, with normal wear and tear.
