Timothy,
You used “overhaul”. My plane’s engine is in sort of the same position; 275 on cylinders and 30 on the bottom end. The bottom end work was done due to the wind blowing my hanger door off of the tracks and into the spinner and prop. The crank and cam were still standard after 2200 hours of total service.
The following questions are rhetorical, just to give you something to think about and perhaps check on.
I presume that the engine time is the same as the airframe. Even though the TBO is 1500 hours the engine really has more like the 900 hours since the case was split. If the work that you described was done by a good shop I wouldn’t be afraid of it.
If you do have any cylinder problems they can be taken care of as they happen. I once to used the logic that if one cylinder went bad it wouldn’t be long before they all went bad and replaced them all. Wrongheaded thinking, just fix what needs fixing. Some of these 0-470 have been going for 4000 hours fixing things as needed. I refer you to the Cessna Pilots Association. One of the editors flys a 310 with very high time engines. However, if you aren’t comfortable figure around $3000 to $6000 to repair or replace the remaining four cylinders and figure that into your price.
CPA is also a good resource on 182s. They have a pretty good pretty good 182 fourm.
When were the mags and wires replaced? How about the alternator and starter times? It has wheel pants so it is hard to see the brakes but they need to be checked out; it is real easy to spend a grand on them.
The prop is also a 1500 hour TBO item. How long since overhaul.
Does it have wet wings or bladders? If bladders then take a look at how long they have been in service. It looks like to me that the life for them is around ten to twelve years.
From the pictures the plane looks really nice. (If my plane had that paint job I’d quit calling her the WartHog.)
VERY nice panel.
One thing that I would recommend for any carbureted 0-470 is the installation of a carb temp gage: they can be very inexpwnsive. I just put one on mine and I am amazed how cold the venture gets. In your part of the country that could spell real trouble.
Good Luck.
