It’s not obvious that your car has bent pushrod symptoms. Every failure has a cause behind it. If you still don’t know why don’t hesitate to find out the reasons and solutions below right away!
What Is The Role Of Push Rods In Cars?
The push rod in cars is cylindrical in the overhead valve engine operated by a camshaft that closes and opens the valve.
The push rod has two ends with openings that will move back and forth to transport and receive oil for the rocker arms. As a result, internal combustion engines operate optimally.
If anyone has a car using an overhead valve engine, it is customary to encounter a bent pushrod problem at least once.
The lever (or crank) is also a part of the pushrod that plays an essential role in the internal combustion engine to support the pushrod to work more smoothly.
Signs To Identify Bent Pushrod Symptoms
If you don’t pay too much attention, it may be difficult to notice the bent pushrod symptoms. Most of the warning signs are from a variety of other faults in your engine system.
In short, if you don’t want to spend too much money on repairs, pay attention to some of the following symptoms:
# Engine fire
When the push rod is bent, the car cylinder will not work correctly. You can get this signal when one or more cylinders suddenly appear abnormal.
Specifically, when the ignition cylinder is wrong, the fuel injector, plug coil, or spark plug is damaged. If you suspect that the pushrod is malfunctioning, have a visual check for accuracy.
# Sound in the engine
Similar to blinker blinking fast error, the sound is one of the apparent expressions to evaluate whether a specific part of the car is still working well or not.
So what do bent pushrod symptoms sound like? When the push rod is bent, it will cause a ticking sound; however, before it reaches this stage, it means that your pushrod is long gone.
# Low Compression
The compression of the engine is called the meeting of air and fuel in the engine cylinder. This process is necessary for your engine to run smoothly.
If anything goes wrong during this process, you’ll run into problems like fires when starting the engine, rough idling, or poor performance when idling or driving your cab.
As explained above, the push rod helps to open and close the valve. If the pushrod is bent, it will not slide freely up and down, thus causing a delay in the opening and closing of the valve.
# Check And Fix Bent Pushrod Rods
Many other factors can cause low compression in your engine. You may experience a low reduction on one or all cylinders.
You must know how to inspect your pushrods to see if they are bent with the naked eye.
For visual inspection, you need a quality and functional mechanical toolbox.
Open the bonnet, disconnect the throttle cable if it gets in your way. Remove any cords that are in your way.
Unlock the attachments that hold your valve cover.
Hold the pushrod with your fingers and play it; it should play freely – not too loosely.
If it’s hard to play or it seems like there’s a lot of space, take your wrench socket and open the latch that holds it with the wrench.
You don’t have to take it off. You can change the arms of the rocker.
You may not be able to detect all bent thrusters just by looking at them or playing with them. To make it easier, take a piece of flat plywood or preferably a piece of glass and roll the pushrod over it. You will quickly find out that the Bent pushrod will not roll freely on the glass if faulty.
How To Replace Bent Pushrod Symptoms?
A bent pushrod can not only affect the operation of your engine, but it can also seriously damage other components if the problem is not addressed immediately.
The reason is that if a pushrod is severely bent or it breaks, the pushrod can pop out of the valve lifter and swingarm and fall through the engine into the oil pan.
It is not enough to replace the pushrods. A technician must also diagnose why the pushrod is bent in the first place.
- Step 1: Remove the valve cover on the affected shore of the engine.
- Step 2: Shake all the pushers to determine which rod or rod is bent and mark it with a yellow crayon.
- Step 3: Remove the swingarm by unscrewing the nut on the bent lever if the vehicle comes with a separate lift. If the motor is equipped with a rocker shaft, remove the rocker shaft assembly by loosening the bolts that secure it to the head. Use an appropriately sized ratchet and socket wrench to remove nuts or bolts.
- Step 4: Remove the bent pushrod by pulling it up over the cylinder head by hand and setting it aside. Inspect all other thrust rods for wear or cracking if the engine is with a swingarm assembly. If severe damage on one cylinder holder, it is prudent to inspect the other bank for damage.
- Step 5: Inspect the rocker shaft and all cranks and springs on the post for damage and replace any worn or damaged parts if necessary.
- Step 6: Check the valve spring for broken or damaged and the visible portion of the valve shaft to ensure that they are straight and not excessively worn.
- Step 7: Install a new pushrod in place of the bent pushrod and reinstall the other pushrods by placing them over the cylinder head by hand, ensuring they are all in the valve lifter. Reinstall the lever shaft assembly or the lever to ensure that all pushrods remain in the valve lifter and the regulator arm or shaft.
- Step 8: Start the engine and adjust the valves if not equipped with a kick shaft. Observe the operation of the lifts and levers to ensure that they are working correctly.
- Step 9: Replace valve cap and valve cap gasket and clean all oil from the engine compartment. Test drive the car to make sure there are no further problems and check valve covers for leaks.
Conclusion
Finally, our above article has given you all the signs and complete steps to fix this error. Your remaining task is to follow the turn to get the engine stable again.
Good luck!
