I got 286,910 miles on my 4.0l, put a rebuilt head 1000 mikes ago with no issues at this time. Keep the heat gremlins away from your engine and it will definetly make another 100,000 ... probably go thru a couple of rear main seals, a thermostat or two and a waterpump. Good luck to you !!
I put a new water pump in about two months ago and I did my thermostat last weekend and while I was at it I changed the spark plugs. I'm doing oil this weekend. Plus I'm in the south so rust isn't really an issue for me
