SOURCE: I have an 2002 Jeep Liberty that keeps throwing

yeah it needs a new cylinder I see this all the time. The valve stem guide in the head drops and sticks the valve open the rocker and cam lose tension and thats why the rocker keeps breaking. Take the valve cover off the head that your have problems with. remove the rocker put a socket over the valve spring. gently tap the spring down without loosening the keepers. You will notice that the valve will not return to the closed position. I garuntee this is the problem u r have I hate to give u the bad news.

SOURCE: rocker arm come out on jeep chrysler 3.7 eng

A rocker arm is the arm that sits on top of the valve stem and connects to the push rods 'the push rods sit on the cam so when engine is running, the push rods go up and down in a timed sequence and with the rocker arms, open and close the inlet and exhaust valves. the rocker arm is located inside the valve(rocker)cover .If the rocker arm gets loose or comes out.
Check the nuts on the shaft which holds the rocker arms.either the shaft or nuts are got loose.They need to be tightened.Don't make it too tight or too loose.  Too tight,and they don't flutter right. Too loose,and they allow the rocker arms to wiggle out of whack. Other possibility can be  something is broken, bent, collapsed, or out of adjustment. 
Thanks. you can rate this solution and show your appreciation.

Need torque on 1997 chevy tahoe 5.7 rocker arm torque


The rocker arms need to be adjusted, they are not set to a specific torque, they use self locking "crimp" nuts to hold the adjustment, these nuts should not be used over to hold the adjustment replace them.. With the lifters fully "pumped" up tighten the rocker arms to "zero" lash, the turn them in an additional 3/4 turn, you are done.

I just need the procedure and the torque specifications for installing rocker arms and push tubs on my 91 jeep cherokee 4.0


Place each push rod in the hole in the cylinder head made for it, make sure that the rod is straight and seated in the lifter, not next to it. Rocker arms are mounted on "bridges". Place a bridge assembly where it belongs and set the rockers on top of each corresponding push rod. Tighten each bolt, alternating between each so you don't pull it over to one side. Torque spec. is very low, being only 19 foot lbs. (I generally go a bit tighter, but don't go crazy with that. 25 is probably the snapping point)
You will find that certain cam lobes will be in the "up" position. You can still tighten down the bridge as long as you are careful, or you can rotate the engine by hand so the cam turns off that spot.
After you are finished, rotate the engine twice by hand and watch each rocker arm to make sure it is moving up and down as intended. If you feel any binding, stop and find out why.
Torque on the rockers is not super critical so if you don't have a wrench that goes that low, just tighten them carefully and don't pull on the wrench like you are trying to pull the crankshaft up through the head and you will be fine.
