Question about 1998 Dodge Ram 1500 4WD

The rocker arms keep breaking. I was wondering what could be causing this and how to permanently fix it. I have not had any problems with them until recently and now they seem to break every couple months.

Wear is usely the reason, I don't know how many miles you have on it, but you might be money ahead to buy a set of after market rockers arms from summit racing or someplace like that, there made out of heaver and stronger metal and not that much more in price than the stock pieces.

The small block Chevy engines commonly wear down and break rocker arms. The chirping is caused by a lack of oil between the rocker arm and ball.

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

2004 Cavalier broken rocker arms after head gasket repair.


Rocker arm issues are common in that car. They can happen without any reason. This is not going to be cheap to look at. When the head was repaired it had to be removed. The timing chain might not have been properly tensioned. That would cause the timing chain to slip and then you have pistons slapping valves and spark plugs. This cause rocker arms and pushrods to bend or break and also can damage pistons.

  1. Clean the rocker arms and pedestal bolts in a suitable solution and inspect for wear. Make sure to clean all of the thread adhesive from the rocker arm pedestal bolts.

To install:
  1. If removed, install the pushrods and make sure they seat in the lifter.
On 1998-99 vehicles, the bolts rocker arm bolts are designed to permanently stretch when tightened. The correct part number fastener must be used to replace this type of fastener. Do NOT use a bolt which is stronger in this application. If the proper bolt is not used, the parts will not be tightened correctly, and part or system damage may occur.
  1. Apply a threadlocking compound to the bolt threads before reassembly.
  2. Install the pedestal and rocker arm assemblies, then tighten the retaining bolts as follows:
    1. 1988-92 vehicles: 28 ft. lbs. (18 Nm).
    2. 1991-98 vehicles: 19 ft. lbs. (29 Nm), plus an additional 90° with a torque angle meter.
    3. 1999-99 vehicles: 11 ft. lbs. (19 Nm), plus an additional 90° with a torque angle meter.

  3. Install the valve cover(s), as outlined earlier, then connect the negative battery cable.
  4. Start engine and check for fluid leaks and listen for valve train noise.
I hope this helps, and just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment.

Have a nice day and thanks for using FixYa.

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.

Is it expensive to fix a rocker arm


Well, the rocker arm itself is not a huge cost, but the CAUSE may be. Something happened to cause the failure, and you need to find that. If it is an oiling issue, for example, that can be quite costly....Rocker arms do not just fail.

Loud rattle noise in Camshaft


First, your engine has rocker arms, if you have a 4 cylinder you have 8 rocker arms, and if it is a 6 cylinder you have 12 rocker arms. Now if it is indeed a rocker arm making the noise, the cause is most likely a bad lifter or a worn cam shaft.

I have an 2002 Jeep Liberty that keeps throwing rocker arms. Has anyone else had this problem? We have replaced lifters, rocker arms and valve springs any ideas? This always happens on cold start up


yeah it needs a new cylinder I see this all the time. The valve stem guide in the head drops and sticks the valve open the rocker and cam lose tension and thats why the rocker keeps breaking. Take the valve cover off the head that your have problems with. remove the rocker put a socket over the valve spring. gently tap the spring down without loosening the keepers. You will notice that the valve will not return to the closed position. I garuntee this is the problem u r have I hate to give u the bad news.
