Great week......not!

Newer Jeeps are just trouble. Plain and simple. Mine is a 4.0, though, so I have never had a motor problem. Oh, 4 liters will death knock with the best of them, but do 250k that way.


My neighnors 4.0 had the knock. He has new bearings, rockers and lifters and it wont go away.

I will mention the piston thing to him.
