The lash adjusters and rocker arms are one piece and that is how you replace them.

Need torque on 1997 chevy tahoe 5.7 rocker arm torque


The rocker arms need to be adjusted, they are not set to a specific torque, they use self locking "crimp" nuts to hold the adjustment, these nuts should not be used over to hold the adjustment replace them.. With the lifters fully "pumped" up tighten the rocker arms to "zero" lash, the turn them in an additional 3/4 turn, you are done.

Dodge neon 2.0 L sohc how to remove lifters from rocker arms


Ok here is the deal, the lifters are poorly designed and prone to noise or "tick", the way to silence this is not just new lifters but new rocker arm assemblies which include new lifters. Use the best parts not the cheapest ones, factory new one are improved from previous designs. If you still want to just replace the lifters you must take the rockers to a machine shop and have the lifters pressed out and replaced by them. Another suggestion is if you live in a warm climate use 10W-30W synthetic oil.

What causes engine knocking and stronger engine knocking at higher speeds?


Some details here:
COLLAPSED LIFTER NOISE
Worn, leaky or dirty lifters can also cause valvetrain noise. If oil delivery is restricted to the lifters (plugged oil galley or low oil pressure), the lifters won't "pump up" to take up the normal slack in the valvetrain. A "collapsed" lifter will then allow excessive valve lash and noise.

VALVE LASH NOISE
If you can rule out lubrication-related problems as a cause, the next step would be to remove the valve cover(s) and check valve lash. On older import engines, mechanical lifters require periodic valve lash adjustments (typically every 30,000 miles). Too much space between the tips of the rocker arms and valve stems can make the valvetrain noisy -- and possibly cause accelerated wear of both parts.

To measure (and adjust) valve lash, you need a feeler gauge. The gauge is slid between the tip of the valve stem and rocker arm (or the cam follower or the cam itself on overhead cam engines) when the piston is at top dead center (valve fully closed). Refer to a manual for the specified lash and adjustment procedure. Also, note whether the lash spec is for a hot or cold engine (this makes a big difference!).

On engines with hydraulic lifters, oil pressure pumps up the lifters when the engine is running to maintain zero lash in the valvetrain. This results in quiet operation. So if the rocker arms are clattering, it tells you something is amiss (bad lifter or worn or damaged parts) or the rocker arms need adjusting.

DAMAGED ENGINE PARTS NOISE
Inspect the valvetrain components. Excessive wear on the ends of the rocker arms, cam followers (overhead cam engines) and/or valve stems can open up the valve lash and cause noise. So too can a bent pushrod or a broken valve spring.

RAPPING OR DEEP KNOCKING ENGINE SOUND
Usually bad news. A deep rapping noise from the engine is usually "rod knock," a condition brought on by extreme bearing wear or damage. If the rod bearings are worn or loose enough to make a dull, hammering noise, you're driving on borrowed time. Sooner or later one of the bearings will fail, and when it does one of two things will happen: the bearing will seize and lock up the engine, or it will attempt to seize and break a rod. Either way your engine will suffer major damage and have to be rebuilt or replaced.

Bearing noise is not unusual in high mileage engines as well as those that have been neglected and have not had the oil and filter changed regularly. It can also be caused by low oil pressure, using too light a viscosity oil, oil breakdown, dirty oil or dirt in the crankcase, excessive blowby from worn rings and/or cylinders (gasoline dilutes and thins the oil), incorrect engine assembly (bearings too loose), loose or broken connecting rod bolts, or abusive driving.

Bearing wear can be checked by dropping the oil pan and inspecting the rod and main bearings. If the bearings are badly worn, damaged or loose, replacing the bearings may buy you some time. But if the bearings are badly worn or damaged, the crankshaft will probably have to be resurfaced - which means a complete engine overhaul or replacing the engine is the vehicle is worth the expense.

ENGINE PINGS OR KNOCKS WHEN ACCELERATING
The cause here may be Spark Knock (Detonation) caused by an inoperative EGR valve, overadvanced ignition timing, engine overheating, carbon buildup in the combustion chambers, or low octane fuel.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

I need the engine valve spec for a 1984 chevy 6.2 diesel. We are adjusting the valves.


VALVE ADJUSTMENTS All gasoline and diesel engines in this guide use hydraulic valve lifters, which require no periodic maintenance or adjustment. However, in the event of cylinder head removal or any operation that requires disturbing or removing the rocker arms, the rocker arms must be adjusted in order to position the pushrods to allow the hydraulic lifters to maintain zero lash. Refer to the valve lash adjustment procedure under Rocker Arms, earlier in this Section.
