So,
2000 XJ
4.0
AW4
4WD
140k miles
Been drinking coolant like a sonofabitch, none of it on the ground (a gallon a week easily). On a drive recently, CEL starts flashing, massive power loss, shuddering, very unpleasant.
Milked it home, checked oil, not milky. Checked plugs, looked fine. CEL code was a P0306, misfire on 6. Cleared the code, restarted the truck.
Now i have a rattle and an occasional stumble, no real power loss (havent been more than 30mph since clearing the code though).
What is this noise? Im thinking maybe collapsed lifters? Burnt valves?
Ive tried searching but i haven't found a specific enough post.
Any thoughts?
