Sadly,last Tuesday,my beloved Jeep suddenly and without warning dropped a valve seat (maybe several) and bit the dust. Engine is toast....just like that!
I ran a bunch of errands that day and made several stops. Truck ran as smooth as it always had for years. On a restart, out of the blue, it ran very rough and would barely idle. The CEL began flashing so I shut it down. My scanner showed a code of "P0300-random misfire". I thought it was a computer or sensor or ignition issue. Had it towed to a trusted mechanic who gave me the bad news the next morning. A video from the borescope proved him right.
I know the valve seats on these motors can drop if overheated but the truck NEVER EVER came close to overheating in its entire life and I'm the original owner. What a major disappointment from my truck that I maintained so well and was sooo reliable for 153,000 miles.
Still can't believe this happened. I thought for sure it would have made it to 200,000 miles and beyond. SMH.
