Not leaking but really have not but any miles on since I bought it. To busy replacing parts to drive it. I have had it less than a month and have installed fuel injectors, full rear brakes with hardware cables and lines, front brakes with new calipers, brake master cylinder, both transmission cooling lines, radiator hoses, tps sensor, new radio and speakers. Tonight cleaning all the different grounds and it looks like the two close to block passengers side will need replacing tomorrow. My plan is to butt splice new #8 wire to some spot on existing wire and add new ring connectors. Think I over payed for this XJ now because it was not rusted but it’s needing more mechanical work than I thought.
