In engines with rocker arm valve systems, the procedure I'm familiar with is to remove a rocker arm cover, and (one at a time!) while the engine is running, slowly back off the rocker arm retainer nut or bolt just until you hear the lifter tapping, then tighten it a quarter turn. If you can identify a lifter that is already tapping, tighten its rocker arm slowly until it stops tapping, then adjust it. Do not over-tighten! This can damage the engine.

Listen carefully to how the engine sounds; if it starts to stumble when you tighten a loose rocker arm, you've gone too far. If you cannot get the engine to run well without tapping, you may have too much wear in the valve train and may be due for a head overhaul, or you don't have adequate oil pressure in the lifters in question.
Repeat until all rocker arms are done. Replace the rocker arm cover using a new gasket, then (in a V-engine), repeat the procedure on the other side of the engine.

Wearing safety goggles, or better yet, a transparent face shield, is strongly recommended. Sometimes oil will squirt out a considerable distance from the lifter side of the rocker arm during adjustment, and the direction is not readily predictable.

SOURCE: Adjusting my idle

To itsgr:
What make, model, year is your car? What engine? How many miles?

To deb:
The location you describe may be where the "knock" sensor normally would go. If it is no longer there, it will set a code and turn on the MIL (check engine light). A cheap fix would be to find out for sure what went there, and if it is the knock sensor, find one at a salvage yard, plug it in, and tie it up out of the way so it doesn't move around.

No, they are hydrolic lash/lifters, no adjustment.

Crank the engine until the mark on the damper aligns with the TDC mark on the timing tab and the engine is in #1 firing position.

To adjust a valve back off the adjusting nut until lash is felt at the pushrod. Tighten the nut until all lash is removed. This can be determined by rotating the pushrods with your fngers. When all lash is removed the pushrod will stop rotating. When all play is removed rotate the nut one full turn.

With the engine in #1 firing position the following valves can be adjusted:
Exhaust 1,3,4,8
Intake 1,2,5,7

Crank engine one full revolution - The following valves can now be adjusted:
Exhaust 2,5,6,7
Intake 3,4,6,8

The EA82 does not use shims. Ticking almost always caused by a failed oil pump to engine block gasket failure. The gasket slowly fails which then allows the oil pump to pump air along with the oil. Replace the "Mickey Mouse" oil pump gasket.

2003 buick century how do i know if the lifters can be adjusted or they need replaced?

They are not adjustable. There is a chance you can tear it down and clean it, but there is no adjustment to them.

Ive looked online and find nothing do i have to bring each piston up to install/adjust push rods and rockers on my 99 ford ranger 3.0 v6 need some feedback how to do it right

Look for a term called "valve lash". Some of this is different in overhead Cam engines. If you have hydraulic lifters, they need to be pumped full of oil. You would take a big socket to the crankshaft bolt and use a breaker bar to rotate the engine. Some lifters are not adjustable. Overhead cam engines have the lifter and no pushrods.

Look at a some other engine styles and see what yours is similar to. Like some want you to center the hydraulic lifter by turning the rocker adjustments a designated number of turns. Others want a gap that you use a feeler gauge to set the gap. Even others have a different gap for intake or exhaust valves.

These types of adjustments are often found in the "specification" section.

How long would I be able to drive with my prelude with the lifter needed adjusted not allot I don't think but would I be able to drive a few days or wat I'm new to this stuff but slowly learning

As long as you do not run at freeway speeds you're ok. for a short time. Expensive engine damage will occur if you ignore this. You don't say what kind of car you have so it's hard to tell if you even have adjustable lifters. Not all engines do.

How do i tighten a lifter on a 2003 ford expedition

Solid lifter adjustment

You must remove the valvecovers to access the rocker to valve stem clearance. use the chart I added to have the engine in the correct positions for adjustment. you will need a feeler guage set also. good luck, keep me posted if any more questions

Rough idling, vibration and reduced power

sounds like your ignition timing is mal-adjusted. The timing is off. Go buy a Haynes repair manual and look in the section on how to re-time your motor. Has to do with re-adjusting the distributor's position in relation to the camshafts (you have 2). You may also need to change the timing belts.

The vibration is due to the rubber in the motor mounts wearing out. I change mine periodically with Urethane motor mounts.

Are the valves adjustable?

hi, on your vehicle the valves are not adjustable after about 1990 they started using hydraulic lifters, so if you have top end engine rattle then the chances are these lifters will need replacing or worse case the cam lobes could be worn if this is the case then your going to need to do a top end rebuild.

to replace the hydraulic lifters your going to need to remove the cams so as you can get to the lifters under neath the cup they sit under so its quite a big job.

the older type valves were a lot easier as you could adjust them with screwdriver and measuring guages but they started using the new ones as they made less noise and lasted longer, but the downside to this was that you need to do more work to replace the lifters.

let me know how you get on or if you need further assistance ok

Need to know if I can adjust the valves on 86 Ford Escort

normally they are not adjustable, look at your rocker arms, do they have a nut and screw threaded into them? if not they are not adjustable, are having trouble with lifter tapping noise? this happens to not adjustable valve engine due to lifter wear, the hydraulic lifters lose their ability to hold oil pressure so they create space instead of elimanating space, and should probably be replaced. Hope this helps, let me know

Lifters are adjustable...While running, back off 'till clacking, then turn down 'till just stops making noise, then 1/4 to 1/2 turn further down. Don't do this anywhere you don't want oil all over the floor. It gets messy. (someone used to make "bibs" for the rockers to keep oil splash to a minium don't know if available any more)
If they do not take adjustment, check that all rockers travel the same distance. Any that do not likely have worn lifters. Don't bother replacing any that are dished on the cam end. cam will need replacement as well.
