This has been a great vehicle! About 2 years ago the 1st significant problem occurred. The oil pressure dropped to almost zero at idle, by maintaining only a slightly faster idle, it was enough to get out of my perceived danger zone. Jeep says it is a seal on the camshaft which failing and the engine would need to be pulled to repair, but with the high mileage they say swap the engine for $5600. Next the cooling fan failed and the electric radiator fan would not operate. I did not drive the vehicle often so I have no idea how long or how many times the car ran at high temps. At road speeds of course it was never a problem. I changed the fan myself and only a few months later, there was a recall notice and Jeep put a new one in anyway. A few months after that the cooling fan relay quit and after taking the grill, front bumper, right headlight, inner fender and some other stuff off, changed that too. Then I started getting water in the oil. The car ran great the whole time, did many trips over 1600 miles, just with oil changes every 1000 to stay comfy. I put in some copper based head crack sealant and it worked very well actually, and oil changes went back to 3000 miles. Finally my wife started it in the driveway one morning and it sounds like it is finally cracked a head or between cylinders. My mechanic down the street has a similar problem with his and replaced the head. I have the car in my garage, since my wife wants the new engine. I bet it would start immediately right now. Other than brake jobs every 6000 miles until the upgraded front calipers, this has been and still is a great vehicle

In all fairness this has been used to occasionally pull a pretty heavy trailer though I did it carefully and there never was large mountains ect involved. These engines are legendary for running 200,000 miles without missing a beat. Mine developed a slight tap which is pretty common in them as well nearly always being a sticky lifter which is no big deal. I never could tell whether it was a ring slapping around or just a tappet hanging as it affected it little if at all until it suddenly blew. Possibly a poor fitting ring but I can't be sure as I haven't torn down the old engine yet. At any rate the ring gouged the back of #1 and it must have broken and flipped over pushing on the cylinder wall hard enough to pressure crack the casting of the cyl wall on opposite side. It could have been a loose fitted ring or just "crap happens" and since it got that much mileage doing a fair bit of pulling I won't really fault it there. Engine did nothing but require plugs and a water pump in that time otherwise.
