Right now im sitting at 115K in my 94YJ. The PO didnt seem to take care of it to well as the coolant was the worst I had ever seen. Flushed the coolant, Did a complete Tune-up: Plugs(which actually looked pretty good) Wires, Dist, Fuel Filter, Sea Foam. She seem to be running pretty strong. I do have some tapping going on and I think I am going to have to put new rings in, but hey I'll drive it until it dies.
