Run the engine until it reaches operating temperature. Remove one valve cover. Use a socket wrench . There are gizmos that you can put on the end of the rocket arms to help with the mess. start the engine. Loosen one rocker stud nut until it clatters. Slowly tighten the stud until the clatter stops. Now tighten the stud nut. 3/4 turn 1/4 turn at a time. repeat this for the rest of the rocker arms. Replace the cover and repeat on the other side. Expect a mess.

Rocker arms are set to a specific preload or backlash on v8 Chevies. There is no torque specification.

The rocker arms are not torqued to a specific setting. Follow the instructions in any repair manual for the proper method for adjusting backlash.

Depends what kind of cam are you running... solid or hydraulic?

Each rocker arm has a bushing beneath the rocker arm screw. When the bushing is worn out, the rocker arm will continue to loosen up.

Most 350's I know of have hydraulic lifters. You don't adjust them. take the valve cover off get some thing to put on the side of the head so no oil splashes on everything start the engine loosen one rocker till it rattles the tighten till it stops rattling and go 1/4 turn after that then do the rest same way

Pull the valve covers off. loosen the rocker arms with out taking them all the way off. then you can turn the rocker arms to pull the push rods out. replace push rods, and tighten rocker arms back down and put valve covers back on

There are no adjustments on a stock Pontiac valvetrain. You simply torque them to 20 ft lbs. Pontiac did not use locking rocker arm nuts. Any attempt to adjust them like you do a Chevy will result in the rocker nuts backing off.

Any under the hood components will have to be moved to gain access to the valve covers. Remove the covers. The rocker arms are held in by one nut per each rocker. The rockers need to be unbolted, removed, and the push rods inspected. the arms need to be set to the gap desired, depending on how the engine will be used. Reassemble the parts on the engine.

There isn't a torque setting. You adjust the valves by tightening each rocker arm until there is no clatter and then tighten them 1/2 turn more.

Yes. Probably need to buy the self-aligning type.

There are no torque specs for a 350 Chevy. Follow the valve adjustment instructions in any repair manual for any small block Chevy.

The process is quite simple but you shouldn't just adjust one. They all work together and should all be adjusted when they are gpoing to be done. Engine has to be set at TDC. There are specs involved in the proper push rod to rocker distance. Best left to a qualified mechanic that knows the process.

i set the parking brake on my 2002 f-350 and it does not hold. I havent found where to adjust it on the truck. Can I adjust it or do I need to take it to a repair shop?

If it's actually the rockers arms that are "chattering" while the engine runs, you may need to adjust the lash. If there are Solid lifters in the engine, you may want to switch to hydraulic lifters and adjust the rockers to the moment of "zero lash". Adjust them in pairs per cylinder while the lifters are in the down position (both valves closed). When you reach zero lash on the rocker arm (the pushrod will suddenly stop spinning freely in your fingers) add an additional quarter turn to the rocker arm nut to set the "pre-load" of the lifter. This just means that the pushrod will be pushed down slightly in the spring loaded hydraulic lifter and when the engine runs, the oil pressure will keep pressure on the lifter and thus the rocker arms will run silently. More detailed info at BoxWrench.net if you need it...

The rocker arms are probably adjusted too tight and hanging valves. Or the rings were installed incorrectly. You will be lucky not to need a new cam if it's you rocker arms.

A 1995 Chevrolet Tahoe has a 5.7L 350 TBI V8 for a engine, not a vortec.

350's use rocker studs instead of bolts, and they are mounted to the heads.

The Chevrolet 350 engine (1967-2003) uses adjustable hydraulic lifters that are individually adjusted by means of the rocker arm nut. The rocker arm nuts are not torqued down. Typically the rocker is tightened down to 0 lash then the rocker nut is turned in one full additional turn.

User Avatar

take off the valve covers, and the rocker arms will have adjusting nuts on them, tighten them to zero lash and the back off 1/4 turn.

According to Champion spark plug applications chart, the correct gap for 1995 Chevy Tahoe 350 engine is .035
