Try a cup of tranny fluid, Dextron, or whatever, in the crankcase. Or there are lots of lifter products at your local part store. I would certainly try that first. I assume your oil has been changed recently, and the level is good. You don't have to pull the heads, but you do have to remove the intake, and valve covers.

Audi a4 1998 tapping noise only when idles under valve cover


Sounds like a bad valve lifter or a valve out of adjustment. It's probably a bad hydraulic valve lifter. In idle, when the oil pressure is lowest, it is not filling with oil. When the motor revs up, oil pressure rises and fills the faulty lifter.
If you do have mechanical lifters, the valve is probably out of adjustment. If you do car work, pull the valve cover and see if it's adjustable. Of course, you'll need the specs from VW/Audi.
Otherwise, it's probably a shop job.
Sorry.

What do i do for tapping lifter


If your rocker arms are adjustable you can adjust that rocker arm by tighten it up a little at a time until tapping stops but,if the rocker arms are not adjustable or have a net lash then you will need to replace the lifter.

2003 hyundai accent 1.5L. tapping like valves need adjusted but engine has hydraulic lifters. Do the lifters need replacement?


Probably a combination of parts. Lifters and or rocker arms. Could be dirty lifters also. If your ready to change oil, what I do is get the engine to operating temperature. Pour a half quart of transmission fluid in and let it run 15 to 20 minutes. It's high detergent and helps clean out the lifters. If the lifters are tapping from dirt, this will stop the tapping or at least quiet it down some.

How can you adjust the lifters 1993 ford festiva


this car uses hydraulic lifters. If your lifter is tapping, make sure the nut is tight on the rocker arm. If it still taps, the lifter has failed and must be replaced.

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

Tapping sound from motor


If it is in fact a lifter noise, there is no adjustment, just replacement of the faulty lifter. I would try some oil additive first and see if this helps. Could also be an exhaust leak at the manifold which may sound like a lifter tap.
