FDS,

My '01 XJ had the engine light come on back in March. 27K on odo. Took to
dealer and also told him of unacceptable coolant loss. Dealer replaced the
#6 plug and sent me on my way. Found no leaks in coolant system. Told me to
watch levels and keep track of usage. 2 miles down the road, light came back
on and I turned around and gave it back to the dealer. Mech put computer
back on and found #6 bad again. Mech grabbed stethoscope and poked around
the valve cover a bit and said that he wanted to pull the cover and have a
look see tommorrow. Tommorrow came and dealer called and said all was fine
under valve cover and was planning on pulling head. 2 days later dealer
calls and said that he ordered a new short block for me. After 10 days, got
jeep back. Asked dealer what happened to block, he said that the lifters for
the #6 cylinder were crushed like stepping on aluminum cans and gouged
badly. Debris was throughout the lifter section. DC wasn't going to take any
chances and wanted block replaced. 3 months and not quite 3000 miles and 2
gallons of coolant dealer replaced head. Then less than 1000 miles later A/C
evap went south.
