My 99 4.0L OHV engine has been running (not very well, mind you) on only three cylinders for the last year. The exhaust valves were burned. The number 6 cyl. was only about 85% intact, the #1 was about 75% intact, and the #5 was about 90% intact. None of them held liquid with the head upside down off the truck. I finally got enough money to replace the heads, and got the new ones on. Runs great now. I will get some pics up to show the valves shortly.
