Just got engines for my T310-Q (TSIO 520-B). I had light Crankcases and non
VAR Crankshafts, so I couldn't get any core credit for either. So overhaul was not an option. Called AirPower and found that there are no new TSIO 520-B's available. So I opted for factory remans. They dont care if the cases are light or the cranks are non VAR. $31,000 each, included the Turbo's. I was about 150 hrs over TBO and have replaced 5 cylinders in the 800 hrs I have owned the airplane. I had 2 first run rebuilt Milleniums that never really had good compressions, so we didn't do that any more. The 3 new continentals are still on the old engines and still have compressions over 75. That's just my experience your milage may vary! Call a couple of the places and ask you may not get core credit for the cracked case. Good Luck Mark Manes N28409 "f" wrote in message ... Today was not a good day for the Baron. While replacing a cylinder I found a crack (confirmed with Dye Pent) off the #5 cylinder leading up towards the case halves. The engine has 2750 Hr since new and about 1000 Hr since a TW Smith overhaul. The case is repairable, but it seems like a waste to not do the overhaul. The question is has anyone recently purchased a Factory New engine? The cost is about $4K more but the parts are not a mix of old parts. The engine is an IO-470L. Any thoughts and opinions will be a great help. Paul |
