The owner says that he did a top overhaul replacing the cylinders with Millenium high compression cylinders (SL10302-A20P) making the engine an O-235-J. From a little digging around on the internet it actually looks like this would have reduced the TBO from 2400 to 2000. Does this seem correct? I know this is another beginner questions but how does the TBO work? Can you continue flying the engine past TBO if it is good condition? Do you need a mechanic to review the engine on a hour mark or just annually if you are over TBO? Just trying to decided if the Long Ez is priced correctly and what the engine might be like for the next 200 -400 hours. I would be very grateful it anyone would like to take a look at the ad and give me their thoughts. Thanks! Jon

I'm looking for a little help on a few questions about Long Ez engine hours. I'm looking into the purchase of my first plane and have found a few planes with several different engines hours.What is the TBO for an Lycoming 0-235-L. One plane that I have interest in has 2000 hours on the engine and had a top overhaul 500 hours ago. Millenium high compression cylinders were installed during this overhaul. The engine has compression ratings in the mid to high 70's with no corrosion or wear. I'm look for advice on what to expect in the engine for useful life and when a major overhaul may need to be performed. Thanks! Jon
