Alan Fox Posted January 5, 2013 Report Share Posted January 5, 2013 I recently purchased a M20E out of an estate , Fixed it up , and am trying to sell it.... The problem is that the engine has super low time (>100 hours) and almost 10 years of sitting in a hanger..... How much time do you think I will have to put on it to lessen the big lycoming cam pitting fear......It seems to be a big obstacle , Other than that it is a nice plane...... My IA says that although it does happen , it is not very common.....To quote him , fly the plane , you will be fine...... And I have been flying the plane with no problems.... Just looking for a general concensus...... Quote Link to comment Share on other sites More sharing options...
duke Posted January 5, 2013 Report Share Posted January 5, 2013 change oil, cut filter open and inspect--any debris or metal? Do oil analisys. depending on results, a jug may have to be pulled to visually check lifters and cam. Quote Link to comment Share on other sites More sharing options...
carusoam Posted January 5, 2013 Report Share Posted January 5, 2013 Review the last year's experience that Byron had for things to look for... Although, Byron's plane is a J, it is still an IO 360? Worst case... What is the cost of a preemptive replacement of the camshaft? -a- Quote Link to comment Share on other sites More sharing options...
N201MKTurbo Posted January 5, 2013 Report Share Posted January 5, 2013 If you are really worried, pull off the two cylinders on one side and inspect it. it'll be about 8 hours of labor. Quote Link to comment Share on other sites More sharing options...
tony Posted January 5, 2013 Report Share Posted January 5, 2013 If I were a prospective buyer, there is really nothing you can do to alleviate my fear. My offer would assume an engine rebuild in the next few years. But that's just me given my past experiences. Quote Link to comment Share on other sites More sharing options...
Alan Fox Posted January 5, 2013 Author Report Share Posted January 5, 2013 I'm not worried , I am just wondering if I am going to have to fly it another two years , before someone buys it.. I wouldnt even consider pulling jugs , or replacing a cam , unless there was a problem..... Quote Link to comment Share on other sites More sharing options...
carusoam Posted January 5, 2013 Report Share Posted January 5, 2013 Most educated buyers know the perils, the log will indicate the plane has sat, the price will be negotiated.... It's probably best for the seller to determine the health of the cam, then demand best price for the plane. Making believe it is not an issue doesn't usually command best price. Then again, we're you trying to get full value / best price for this plane? My first M20C had a record of sitting. I negotiated a low price. End result, a stuck valve followed by a new cylinder.... You get what you pay for. Best regards, -a- Quote Link to comment Share on other sites More sharing options...
TTaylor Posted January 5, 2013 Report Share Posted January 5, 2013 The old adage in real estate and stocks applies the same here "You make your money when you buy, not when you sell". You will either have to take a lower price or pay the cost to hold (and fly the plane regularly) or inspect and document the condition of the engine. You took the non-flying and condition into account when you bought the plane and hopefully you paid a low price for it. Spending a few thousand to inspect the cam and take photos and get a mechanic's written report seems like a minor cost at this point versus the cost of holding, insuring, and flying the plane.

jetdriven Posted January 5, 2013 Report Share Posted January 5, 2013 Be careful what you look for. A failing cam is an 8 grand proposition and I have a good idea that on teardown, everything else will need it too. Quote Link to comment Share on other sites More sharing options...
Alan Fox Posted January 5, 2013 Author Report Share Posted January 5, 2013 Its a 40 hour engine, I will probably just fly it another 100 hours and then sell it next year , Quote Link to comment Share on other sites More sharing options...
N601RX Posted January 6, 2013 Report Share Posted January 6, 2013 Although my engine had 1800 hrs on it, it had been sitting for the last 7 years. It was only flow 30 min or so each year to or from annual. My mechanic and I took it apart and overhauled it. Pretty much all the steel parts in it had rust on them. The crank and rods cleaned up and were ok. Cam, lifters, wristpins, and geartrain had to be replaced. If it is pitted and grinding itself up continuing to fly it will make the overhaul much more expensive. Quote Link to comment Share on other sites More sharing options...
