What are the rocker arms connected to?
A rocker arm (in the context of an internal combustion engine of automotive, marine, motorcycle and reciprocating aviation types) is an oscillating lever that conveys radial movement from the cam lobe into linear movement at the poppet valve to open it.
Why is my rocker arm not working properly?
Another reason for your rocker arm failing and causing a valve to remain open is a bent valve. A bent valve can be caused by a few key problems, like your engine over-revving, your engine not being repaired at the right intervals,s and issues during an engine rebuild.
Why is the rocker arm important to the engine?
The valve stem keeps the right air and fuel mixture within the engine, allowing for proper timing of ignition and combustion. When the camshaft lobe raises the arm, the inside of the arm presses on the valve stem to open the valve at the correct time to allow pressure and gas either inside or outside of the system.
What are the codes for the rocker arm?
Specific rocker arm codes that can be scanned using a diagnostic tool and can be seen by the check engine light turning on are P2646, P2647, and P2662, all of which relate to the rocker arm actuator system, rocker arm pressure switch, or the rocker arm system stuck on bank 2.
Can a car run without a rocker arm?

What causes the rocker arm to stick on a Dodge?
If the valve sticks for a fraction of a second too long, the rocker arm can be allowed enough clearance to fall. Other causes can be faulty valve seats or worn or defective valve springs. One indication of carbon build up is a slight tapping noise.
Can a Jeep dealer fix a Pentastar rocker arm?
If Jeep has a rep on this site like some of the other sites have, I would like to speak with them… My guess is that they’ll replace the cylinder head. Depends on your build date as to whether you get parts covered. You will need to actually get a diagnosis from the dealer before the rep can help you.
What causes a rocker arm to fall off a misfire 3.7?
After the valve cover is removed, inspect for sludge, a broken valve spring and quite possibly a “FALLEN ROCKER ARM”. The general consensus among several master techs that I discussed this problem with is “the main cause of a fallen rocker arm in a 3.7 or 4.7 is from excessive carbon build up.”
