I'm having problems getting the rocker arm assemble to go back on and tighten down with out locking the cam where it will not turn at all and that is with bolts finger tight


When the rocker arm assembly is tightened down the lobes on the cam will be pushing the lifters which will put force on the push rods which will rotate the rockers which will open the valves against the valve springs. And,,,
That will create frictional resistance in the entire system, And,,,
Any rotation of the cam will require valve springs to compress.
I know that my old fingers would not contemplate trying to rotate it.
Cheers

Whats the cause of a slightly bent pushrod and a rocker arm to nearly come off?


the high lift cam has no compensation and so the valve retainer bottomed out causing the rocker to slip sideways and bend the push rod
you would have been better fitting a prolonged duration cam rather that a high lift for the following reasons
1 --- you can used standard rocker gear
2 ---there is no valve bounce at high rpm
3 --- smoother air flow in the inlet manifold so there is not such a stop/ start action when rpm is low
4--- less wear on cam followers and cam lobes
cam shafts are all about open duration so longer open with smaller lift is better than the same duration with a fast up and down action

How do I change rear coil spring on 2009chevy traverse


You are first going to have to support the lower control arm that the spring is mounted to. Start by removing the wheel, then disconnect the lower control arm from the knuckle/hub assembly. This should be supported with the jack. Slowly lower the jack and by doing so this will free the spring. You may have to slightly pull it out from the spring seat pocket area. Place the new spring back in the seat and have a helper slowly raised the jack while you position the arm back into position.

Installed new oil pump and now have broken rocker arms


THe rocker arms are broken because there was not enough downward movement in the valves to allow the cam to complete its turn. IT happens when the valve spring retainer either hits the top of the valve guide or the valve springs are fully compressed forming a solid block . If you have hydraulic valve adjusters I would be suspicious of a lack of movement (seized) in the ones that broke the rocker arms

Knocks after you start for a couple mins then stops


Its hard to say for sure .But the most likely thing would be a lifter sticking .It rides on the cam shaft and the push rod sits on top of it and in turn pushse the rocker arm up and thatopens the valve. The lifter is filled with oil but also has a spring inside of it .If the spring hangs up when the engine is cold you will hear a knocking noise until the engine warms up and things expand. It may go away on its owen but make sure you change the oil regulary dirty oil cause this

How do i change my rubber bushings on the front suspention of my 1997 dodge ram 1500


opper Control Arm Bushings
  • To access the upper control arm, remove the shock absorber and the strut bar. Also, disconnect the sway bar from the lower control arm, if your particular Ram model is equipped with it. After that, you can hold the coil spring in place with a spring compressor.
    Secure the wheel hub assembly to the chassis using a wire before you disconnect the upper ball joint. This will prevent damage to the brake hose. When ready, release the ball joint using a ball-stud loosening tool (see Resources).
    The upper control arm mounts to the chassis with a cam bolt assembly. Once removed, you can place the control arm on a vise and remove the bushings using a bushing service tool (see Resources). When installing the new bushings, do not use any lubricant but make sure the flange on the bushing end seats properly on the arm bore. Then re-install the upper control arm. When finished, take your Dodge vehicle to a good shop to align the front suspension.
Lower Control Arm Bushings
  • Remove the shock absorber and strut bar. If your particular model is equipped with a sway bar, disconnect it from the lower control arm.
    Secure the coil spring with a spring compressor and release the lower ball joint from the wheel/hub assembly using a ball stud loosening tool (see Resources).
    Now you can release the lower control arm by removing the rear mounting bolts. Remove the bushings with a bushing service tool (see Resources). When installing the new bushings, do not use lubricant and make sure they seat properly on the control arm bore. Then replace the lower control arm. When finished, take your Dodge vehicle to a good shop to align the front suspension

03 jeep liberty 3.7 liter v6 the rocker arm keeps coming off and it has an overhead cam wondering what all could be the problem


most likely (as seen in my experience), the valves become slightly bent & they don't travel properly within the valve guide, causing the valves to stick open. It will almost appear to be a broken valve spring. I've seen a handful with this problem. The valve sticks open & the cam lobe doesn't even touch the rocker arm, thus "tossing" the rocker out of position.

How to remove the wiper arm on a 1966 Catalina. Please don't tell me to pull up the plastic tab and remove the nut. These don't have the plastic covers and I can't get the metal off to see if there is a...


Look for a tiny lever right over where the arm slides down on the motor cam. If you see it take a screw driver and work it out. It a slide that holds the arm on the slide sets in a groove when the slide is pulled away the arm is ready to lift up. It is spring loaded wo you will need to slide pull up on the back side of the arm to relieve the binding. If this is not it there is something like it that locks the arm to the motor cam.
