Rocker arm replacement

I am going to be replacing my rocker arms soon on my 92 XJ 4.0 I was wondering if anyone that has done this can give me a more detailed explanation than the repair manual. I know it is fairly easy and i have a good idea of how to. The repair book says to bring the #1 piston to TDC and then remove all the rockers a 1/4 turn at a time. Do you have to bring each cylinder to TDC individually before removing the rockers that go to it? That makes more sense to me. I just dont want to mess anything up. Thanks

umm i'd be more worried about putting them back in the right way. from what i know. TDC the first one snug tight then 1/4 turn then the same for each cylinder after that. i'll be doing this on sunday when i replace my head so i'll get it down by then

Guys---there is absolutely NO REASON to run the cylinder to TDC before removing/replacing the rocker arms.

The FSM DOES caution to loosen the rocker retaining bolts one turn at a time, alternating back and forth between the pair, so as to prevent distorting the saddle bracket on top of the pair of rockers. Likewise, tightening them is done the same way--1 turn per time, alternating. Final bolt torque is 21 ft-lbs.

I don't own an XJ any longer, but I still think they are the best of all the Jeep products ever made. My XJ was my favorite vehicle in my 50+ years of driving.
So...I stick around and give advice.

I don't exactly understand your question. Please restate it another way, and I will try to answer.
