In order to accompany your vehicle in the long run, you should get a better understanding of the rocker’s arm. Thus, a lot of newbies in the field want to hunt up LS rocker arm torque.
If you are on the same page with them, visiting our post today might put an end to your curiosity. What are you waiting for? Follow us now to catch up with the best useful information in this field.
In the post, we will pass through two key parts.
The first section is about the LS rocker arm torque sequence, and the other will help you to unclog some of the top tricky questions on rocker arm in the car forums nowadays.
What Is LS Rocker Arm Torque Sequence?
The LS arm torque is 22 lb-ft (or 30 Nm) for all bolts, but you should remember the order of the bolt to be tightened to make sure everything is on the right track.
After figuring out the push rods’ proper length, here is the LS rocker arm torque sequence to torque these rocker’s arms. You’d better take note of the order and follow suit.
The first piston belongs to the compression phase when the sixth exhaust valves and cylinder inlet are rocking.
This stroke shows the intake valve begins its downward motion while its exhaust valve belongs to the travel of upward movement.
When the first piston is on the dead summit center of the compression stroke, revolve the crankshaft.
With the motor in the first firing location, screw up the below valve rocker-arm bolts. In particular, secure the rocker-arm bolts number 8, 7, 2, and 1 of the exhaust valve with 22 lb-ft (30 Nm).
Also, tighten the rocker-arm bolts number 5, 4, 3, and 1 of the intake valve using 22 lb-ft (30 Nm).
Then, revolve this crankshaft at 360°.
Screw up these below valve rocker-arm bolts. In particular, secure the rocker-arm bolts number 6, 5, 4, and 3 of the exhaust valve to 22 lb-ft (30 Nm).
Screw up intake ones number 8, 7, 6, and 2 to 22 lb-ft (30 Nm).
6.0 LS Rocker Arm Torque Specs
The sequence of 6.0 LS rocker arm torque is the same as mentioned above, with the torque being 22 lb-ft.
2006 Chevrolet V6 Rocker Arm Torque Specs
The torque spec of LS rocker arms on this car is 124 inch-lbs (14 Nm).
For lower intake bolts:
- Short Bolts: 18 ft-lbs (25 NM)
- Long bolts: 115 inch-lbs (13 Nm)
For upper intake bolts: 89 inch-lbs.
For head bolts: 37 ft-lbs (then tighten them 120 degrees).
These specs combine with how power we push at the right degrees, which ensures the push rods get right back in the same position they are shown up.
Some piece of advice from experts in this field is that you should equip some tools for torquing the rocker arms, and you can detach them or the back valve cover easily.
2008 Chevy 5.3 Rocker Arm Torque Specs
Of course, the rocker arm torque of 2008 Chevy 5.3 is also 22 lb-ft.
We will walk you through three points of the specs of the car before diving deeper into the engine setup with the rocker arm.

- Engine Type: V8 5.3L
- Number of cylinders: 8
- Fuel Type: Gas
- Valve Configuration: OHV
- Displacement (ci/cc): 323 / 5,300
- Oil Capacity: 6 quarts
- Recommended Oil: 5W-30
- Transmission Type: Automatic
- Number Of Speeds: 4
In order to set up a Chevy 5.3 engine, you have to start with rocker arm torque which is from the internal side of the motor consisting of the connecting rods, crankshaft, and piston ring and then move outward to the pulley-belt system.
If you haven’t had much experience in this sector, having a profound view of these specifications is very necessary to set up or maintain steps with your vehicle.
LS1 Rocker Arm Torque
On the driver side, starting from the front of this motor to the firewall (back side), the rocker’s arms are 1 exhaust, 1 intake, 3 E, 3 I, 5, and 7.
On the guest side, starting from the front to the back of rockers (firewall), are 2 intakes and 2 exhausts, 4, 6, and 8.
So, you will begin with the first cylinder and then turn the crankshaft.
If the exhaust has not yet opened when the push rod is climbing, you need to torque its respective intake. Then, you rotate this crank till the intake locks.
What Is Torque On Rocker Arm Studs?
Many components are engineered for safety, closed course, and high performance. And torque on rocker arm studs belongs to one of these parts.
The element screws into its head casting, which is the component the nut and the rocket arm connect to. They are twisted when set up in this head.
Keep in mind the number 1 cylinder is always at the upward slot. Be cautious, don’t let it askew 180°, which it’s quite hard for you to adjust back to the right position.
If you don’t get the know-how, don’t hesitate to ask your dealership or agencies as an instructor to reach the right cylinder you work on.
Also, it’s best to keep an eye on symptoms of a bad rocker arm like a loud clicking noise or engine stalling.
How Tight Should A Rocker Arm Bolt Be?
After using the torque of 22 lb-ft, you need to tighten them for an extra 30 degrees, using a clockwise rotation.
The rocker activates the engine pivot’s valves on a specific bolt that is slipped into its cylinder’s head.
When these bolts come loose with age, they can trigger rocker arms to spring out of the valve stem and pushrod.
Thus, you need to know how to adequately tighten a rocker arm bolt to prevent problems on other related elements like the intake camshaft position sensor.
When Setting Up A Rocker Arm Shaft, Where Should The Oil Holes Face?
In order to apply oil properly when setting up a rocker arm shaft, you should have at least superficial knowledge of the rocker shaft structure.
The components are similar for both sides, yet they are equipped with a bottom and a summit.
Keep in mind that its stand’s bolts aren’t the same. The second bolt owns a thinner diameter shaft.
Grease has to have upward movement to the head, then around the 2nd stand’s bolt to access the rocker shaft. Be careful to avoid mixing up the bolts together.
