I've seen them go 200,000-250,000 miles before needing a rebuild or replacement. It really depends on how the previous owner took care of it and did all the maintenance. My dads yj had something like 218,000 miles when he sold it(still running great). Maybe you can argue it will need an engine rebuild soon to get the price lower?

I have 208,000 on my 01 TJ. Still running strong! Easiest way other then checking the oil is to stick your finger into the oil fill cap and run it along the bottom of the valve cover or just take the valve off but you'll need to buy a new gasket. No black or chalky sludge then it should be ok. You can also use seafoam but a lot of wouldn't really recommend it. If it was well maintained it could last ya another 100,000. Rockauto.com sells rebuild kits for a decent price.

Another thing to do is to do a compression test on the cyl's I can't remember what the compression is supose to be. but it will test to see if there are any leaks in the cyl's the engine will need a rebuild sooner rather than later. This is probaly one of the better tests to do to determine the shape of an engine.

The thing to remember about a high mileage jeep is that you will probably have a lot more minor repairs and maintenance costs than on a lower mileage jeep. If you can't do all of the work yourself, the labor costs can add up fast and it might be cheaper to buy a lower mileage jeep for more money up front. When it comes time to sell, all of the repairs you paid for won't get you anything back.
And if the engine does give out, can you afford a several thousand $$ repair, or can you do a used engine swap yourself?
