valve adjustment

I did a search but didn't come up with what I'm looking for. Valve cover was leaking so I pulled it to replace the gasket,of course the plastic cover is full of cracks so that's gotta go.While I have the cover off I figured I'd adjust the valves but there is a clip that joins the rockers together on each cylinder so they can't be adjusted independently.How are they adjusted? Also,1 push rod is turning a little slow. Thanks

Umm, if they are the bridged type rockers you speak of, then they are not adjustable. The bolts are simply torqued down to spec and thats it, no adjustment.

it's an '87 with the 4.2. Not being able to adjust the valves is a real bad design.I know they sell a roller rocker kit for that engine,what's the point in not being able to adjust them? There has to be a way.

If i am not mistaken our engines have hydraulic lifters. I think the lifters are suposed to have some sort of automatic adjustment.

yes,we have hydraulic lifters but they should be adjustable through the rockers.

Nope, no adjustment. You just torque them down to spec and go. All jeep 2.5's, 4.2's, 4.0's, and AMC V8's (304-360-401) are like that.
