Jeep Repair: 2000 Jeep GC Limited 4.7Ltr, jeep dealership, gague

Question
Hi,I have a 2000 Jeep GC limited. I am having problems with the rocker arms falling off. I spoke with a mechanic at local Jeep Dealership and he has never heard of this happening before. He thought that there may be some sticky lifters. I have replaced all 16 lifters and still keep having the rocker arms falling off. The jeep has 106000 miles on it. Any sugestions as to what is causing this to happen? Oil preasure is good around 50 to 60 psi on gague.

Answer
I have seen the rocker arms fall off of 2 of them that I have worked on a a few with other guys in the shop. NOw as far as the fix   no one that I have worked on wanted to do anything about it  I will ask some engine guys in the shop tomorrow  if u email me I will ask them and respond back to u.
