Take a look at the push rod for damage, then reinstall pushrod, make sure it sitting in lifter then make sure rocker arm is not damaged, reinstall rocker arm and use some locktite to lock stud in head and use on the nut, make sure to clean oil off the thread then tighten to specs and let dry for a day or two this should not happen again,the key is to let the locktite dry.

I own a 1968 Imperial 440 V8. The intake valve push rod of the #1 cylinder bent and was causing knocking noise. I replaced it and the motor ran fine. The #1 cylinder started missing. Again it was a bent...


bent push rods come from improper movement of the rocker and valve
This can be from an incorrect length push rod-- some v8 engines run different lengths for inlet and exhaust
from rocker arm jamming on the shaft or rocker ball
hydraulic cam follower pumping up and jamming the valve spring to a solid block
bent valve stem above the valve guide
valve spring Colette moved or misplaced incorrect rocker for that valve-- some engines run different length rockers for inlet and exhaust
what to do-- if this engine was running all right for some time then the rocker can be omitted. if the problem has been occurring since the cold weather the the oil may be too thick and not allowing the follower to leak down properly
check the follower or replace it , change to a lighter viscosity oil for the duration of the cold weather
unless you have had a recent head change or other mechanical work done the problem will be in those areas.

Loud tiking sound after recent cylinder head replacement


IF you did not keep that rocker gear and rockers together as units then the noise may be from the wear on the ends of the rockers not matching the wear for the valve ends. If you fitted 1 new valve and did not grind the rocker arm wear out that may be the ticking noise

I have a 96 grand cherokee and my check engine light recently came on got it scanned and was told it was misfiring on the third cylinder just would like to get some extra thoughts about it before i go...


The most common problem is a need for a tune-up. ( Plugs, wires, etc.) It could also be caused by a vacuum leak in the intake runner. Then there could be a bad injector. (kind-of rare on Jeeps) then there is the possibility of a blown head gasket or worn out engine parts like valves, rocker arms, camshaft, pistons, rings, etc.

2002 Jeep Liberty Sport 3.7L V6 Replaced all six spark plugs with brand new ones and replaced coils for 4 and 6 with new ones Still reading misfire Within 10 minutes of starting enging, vehicle idles...


We have an 02 Liberty 3.7L, here at my repair shop, after customer replaced, spark plug's and all coil pack's, brought it here to my shop, was running with two cylinder's miss, did cylinder compression test, no compression on two cylinder's, remove valve cover's, found two rocker arm's off, remove cylinder head's, and found that on those two cylinder's the valve seat's had drop, keeping the valve open, and that's why the two rocker arm's had come off, do a cylinder compression test, could be the same thing, hope this was very helpful.

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.

89 Ranger 2.9L 150k mi. Lifter noise, power lose, oil pres zero


the lifter noise might have been a bearing going bad or a piston ring. if you lost power you probably lost compression on one cylinder. Try checking your compression with a compression tester screwed into your spark plug socket. here is a site with a procedure.

No compression in one cylinder


Timing belt slipped around cam pulley. Take off your timing belt cover and check the position. This would explain misfiring and compression loss. Stretched belt or missing cogs in belt likely culprit.
