Where can I find a good overhaul shop for my Continental IO346 (IO 346 or IO-346) engine? I understand that Teledyne Continental now offers a new cylinder kit based on IO520 cylinders (this is the engine on which the IO346 is based). I also understand that cases, camshafts, and crankshafts have become hard to find. This shortage is apparently worsened by the 1,600-hour TBO of the Continental, versus the almost universal 2,000-hour TBO of the comparable Lycomings. Search strings: IO346 overhaul, IO-346 overhaul, overhaul my IO346 engine
G&N in Griffith Indiana has done IO 346’s in the recent past. They are a top notch overhauler, been to their shop, ran my IO 346 parts through their system.
I can recommend Western Skyways of Montrose Colorado for a IO346 overhaul. They did mine and so far I’ve had 80 trouble free hours. I have changed the oil three times and I’ve never exceeded 1 quart between changes. I recommend that you look at the cylinder kit from Continental. It will add some to the price of the overhaul but I believe it is well worth the money. The only parts real hard to come by are the crankshaft, crankcase and camshaft.
Try Chuck Ney in Tulsa, OK. He did my IO-346 and I have 600 hours on it! Chuck is on the web at http://www.chuckneyent.com/.
