    For clarity’s sake, I’m first going to point out that the 1985 and 1986 model 182’s were still the 182R model with the Continental O-470-U. Cessna did not begin using Lycoming powerplants until the production restart in late 1996.
     
    The Lycoming engine used in the post-production restart 182’s from 1996 until present is the IO-540-AB1A5. 
     
    According to Lycoming Service Instruction 1009AU (found here: http://www.lycoming.com/support/publications/service-instructions/pdfs/SI1009AU.pdf ) the TBO of the IO-540-AB1A5 is 2000 hours, which can be extended to 2200 hours “If an engine is being used in “frequent” type service and accumulates 40 hours or more per month, and has been so operated consistently since being placed in service.”
     
    I would also point out that, for private Part 91 operations, there is no “required” TBO. If you want, you can run the engine until it tells you it’s time to overhaul (excessive oil consumption, bad compressions, and metal in the oil are all ways that the engine will tell you it’s time).
