Dodge Caravan Rocker Arm
Rocker Arm is an essential component of the Dodge Caravan vehicle's internal combustion engine in the valvetrain mechanism through which the motion is transferred from the pushrod to the intake and exhausts valves. Usually fabricated from stamped steel or aluminum, the Rocker Arm translates the movement of the pushrod which is in the vertical plane into the required movement downwards to lift the valves. Aluminium is commonly used in high RPM engines due to its lightweight nature while the cast iron and forged carbon steel are used on diesel type of pistons. Roller rockers, which employ pins that minimize contact surfaces and therefore friction between the valve stem and a lever that guides the valve, may be used in Dodge Caravan models and are part of performance packages, Needle bearings come in roller types to enhance efficiency besides the valve springs that hinge on them for their operation. Against the conventional designs that provide rocker ratio of between 1.5:1 and 1.8:1 in modern engine, provisions of higher camshaft lift results in the enhanced performance. New and improved fulcrum bearings are also used for engine with high RPM in dealing with stresses and enhancing the general Rocker Arm system of the Dodge Caravan intake manifold.

Dodge Caravan Rocker Arm Parts Questions & Experts Answers
- Q: How do you remove and reinstall rocker arms and hydraulic valve lash adjusters in four cylinder engine on Dodge Caravan?A: Before removing the Camshafts, you have to take them off; after doing so, you can also take out the rocker arms. Losing hold of the rocker arms and valve lash adjuster that were removed should be avoided, thus it is advisable to mark each out individually to know which one goes where. Before installing use the opportunity to check the rocker arm tip, roller, and lash adjuster pocket for signs of wear; if any replace them. Each should be inspected in detail but particularly the ball-end which rubs against the rocker arm as these are prone to becoming obstructed; if there is doubt about their condition or if the engine develops 'valve-tapping' it will be wise to replace them. Prior to fitting the lash adjusters should be partly filled with engine oil and it should be noted that when the plunger is depressed, the movement should be minimal. And if there is too much of this travel increase, immerse the rocker arm assembly in clean engine oil and pump the plunger until such travel is nudged out. When filled with oil the Plunger has to move within the rocker arm, if so then the Plunger is defected and has to be replaced. Bolt the hydraulic lash adjusters and rocker arms to their standard position in the Cylinder Head and then replaced the camshafts. The adjusters should make 'tapping' noises in the initial times after restarting the engine after replacement. The process is to keep increasing the engine speed reiteratively from idle to 3000 rpm and back to idle for one minute; if the adjusters are noisy, as they should be, they will have to be replaced.
