merrja Posted September 30, 2015 Report Posted September 30, 2015 I got the pictures back from Triad today from my tear down and I must say that it's worse that I had hoped. Pics attached. The crack in the crankcase under #2 came as the biggest surprise.... Quote
carusoam Posted September 30, 2015 Report Posted September 30, 2015 Now what's the plan? ugh, -a- Quote
gsxrpilot Posted September 30, 2015 Report Posted September 30, 2015 Do you know what caused this? Quote
jetdriven Posted September 30, 2015 Report Posted September 30, 2015 Yes that's a typical lycoming four cylinder. 4 Quote
tony Posted September 30, 2015 Report Posted September 30, 2015 (edited) Those pictures remind me of my engine when I purchased my airplane. Those lifters and galled cam comes from inactivity. I've seen flight school's, who send their engines in for an overhaul because they reached TBO, (that get flown everyday) which looked brand new inside. Best thing for our engines is to fly them Edited September 30, 2015 by tony Quote

aaronk25 Posted September 30, 2015 Report Posted September 30, 2015 Typical lycoming. Ya a lot of us have been there. Sorry for this. Anyone heard of the rotax doing this? I have yet to hear of it! Quote

Best thing for our engines is to fly them not any more. the local flying clubs arrow is having anoth engine put on after 400 hours SMOH two years ago. It flew often. I'm not convinced that's working either. Edited September 30, 2015 by jetdriven Quote

Guest Posted September 30, 2015 Report Posted September 30, 2015 Typical Lycoming corrosion issues. I'm guessing it not the first time your filter had metal in it. Clarence Quote
MB65E Posted September 30, 2015 Report Posted September 30, 2015 Time in hours and Calander time? Where did the lifters come from?Factory cam? Was the crank balanced? looks a bit rough from most overhauls I have seen lately. just a few thoughts. All the best, -Matt 1 Quote
merrja Posted September 30, 2015 Author Report Posted September 30, 2015 700 hours but the overhaul was done in 2005 and I put ~500 hours on in the last 4 years so the inactivity appears to be the culprit. The case is out to see if it's repairable, but I may move up to the factory reman so I can get the roller tappets. More news to follow. Thanks for all the posts! Quote

Thanks for all the posts! unfortunately you likely won't be able to get a factory engine. To be accepted for a core it must be in running operable condition and be less than 35 years old. The core value is 14k and it's going to be a very expensive overhaul because so much stuff was scored from metal in the oil. Edited September 30, 2015 by jetdriven Quote
Htwjr Posted September 30, 2015 Report Posted September 30, 2015 When did Lycoming start using roller tappets on the factory remans? Quote
MyNameIsNobody Posted September 30, 2015 Report Posted September 30, 2015 Not sure what the point is, but I like it! Allow me: A cold piece of idle steel being attacked by the elements with the statement- "Now this sucks". Yes, indeed. This does suck... 2 Quote
merrja Posted September 30, 2015 Author Report Posted September 30, 2015 According to Airpower, if the engine was running when last in use, then you can get the factory rebuild and 0 time. IS this wrong? Quote
jetdriven Posted September 30, 2015 Report Posted September 30, 2015 It cannot be disassembled. Here is their core policy. http://www.lycoming.com/Portals/0/techpublications/serviceletters/SL%20L250A%20(7-29-2011)/Lycoming%20Engines%20Exchange%20Engine%20Core%20Policy.pdf Quote
KSMooniac Posted September 30, 2015 Report Posted September 30, 2015 That does indeed suck. Byron is correct about the core policy and disassembly. Not sure if it is feasible to put it back together or not and give it a try if you're inclined to try to get by with that or not. I believe the case crack at #2 is fairly common for our engines. I'm not sure which engine you have, but I have a lot of good leftover internals from my salvage IO-360-A3B6D that I'll sell for reasonable money. Accessory gears, oil pump, lifters/tappets, connecting rods off the top of my head. No cam or crank, though. It might be helpful if you end up having to rebuild what you have. 1 Quote
merrja Posted November 8, 2015 Author Report Posted November 8, 2015 Engine is now in the test cell at Triad.. Complete overhaul, new crank case, rods, cam, cylinders, prop repack, prop governor.... an expensive day for sure! If I had it to do over, I would have purchased the reman from Lycoming, but hindsight is always 20/20 Quote
jetdriven Posted November 8, 2015 Report Posted November 8, 2015 Seriously how much is this engine going to cost, just the engine itself? Quote
