A push rod may puncture a rocker arm due to excessive wear or failure in the engine's valvetrain components, leading to misalignment or improper contact. If the push rod is bent or damaged, it can cause increased pressure on the rocker arm, resulting in a puncture. Additionally, insufficient lubrication or overheating can weaken the materials, making them more susceptible to failure. Regular maintenance and inspections can help prevent such issues in the engine.
The rocker arm.
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 One component was left out. The push rod sits in the valve lifter that rides against the camshaft
Lack of lubrication.
Transfer motion from the lifter to the rocker arm.
Remove the valve cover. Remove the center nut or bolt that holds down the rocker arm. remove rocker arm, pull out the bent push rod. Install new push rod and put it back together.
The push-rods go through from the rocker arm to the lifter. In this engine, they are on an angle, the lifter is not directly below the dimple in rocker arm. Place all push-rods on lifter, (after making sure the oil passage is clear) then install rocker arm assembly, be careful each pushrod is in the dimple, and carefully tighten rocker arm assembly, start in middle, go to ends, back to middle and work your way to ends, then go back again with a torque wrench and do all to spec.
The function of a rocker arm is to control a valve in an engine. The rocker arm is a lever that rocks.
take valve covers off and then unloosen each rocker arm and pull the push rod out, install new push rod and install rocker arm back on and tighten down nut according to factory specs.
Push rod.
on the 1.6l it does not have pushrods . it has an adjuster on the end of the rocker arm.
Remove the valve cover. The rocker arm assembly can be removed by loosening the rocker arm screws. Each rocker arm will have a screw.
The rocker arms are small devices that press the valves open. Typically, "lifters" ride on the camshaft and press a push rod. The push rod presses against the rocker arm and the rocker arm opens the valve.However, overhead cam engines do NOT have rocker arms.Saturn engines come in three basic varieties:The 4 cylinder single overhead cam engine (note the fact that it has an "overhead cam".The 4 cylinder dual overhead cam engine.The 6 cylinder dual overhead cam engine.None of which use rocker arms.
