I wanted an engine to put in the RV-6A and fly, then overhaul later. I found this O-320-E3D engine through our Van’s Minnesota Wing. The engine had 2,244 hours, and had never been opened (except the accessory cover for the oil pump AD). Both mags had been replaced at 2,000 hrs. It was running good, but metal was found in the filter during annual. The owner replaced it with a salvaged engine, and I bought the core from the owner.
Upon teardown, the cam and lifters were
found to be the problem, as is common for these engines. It would
have been possible to replaced the cam and lifters and fly it, as the plain
steel cylinders were within service limits. I decided to do a complete
major, with an increase to 160 HP. I followed the Lycoming recommendations
for replacement and inspection of items for a major overhaul.
The total cost was $7,957.
