Tapping valves is a noise made by too much clearance between the valve lifter and the valve. Modern engines have hydraulic lifters. If you have too little oil pressure or run the engine low on oil, the lifters will make noise. The lifter can also wear out.

It depends, but it could be the lifters. If you have hydrolic lifters, they will lose oil when they are not run and "collapse". It will take some running time for the lifters to refill with oil (not sure how long exactly - ten minutes?). If the sound goes away after a little while, it might have been the lifters.

How do you stop tapping lifters?

Sometimes putting a jug of transmission fluid in your oil will clean the junk out of your lifters and stop your noise - if it is an older vehicle with adjustable rockers you can adjust and get rid of the knock.

As a guess ... your lifters are "loose", need more oil, Miracle Oil, or just a cleaning.

Why does lifters rap when you first start your 97 lumina ls but clears up until next morning when starting again?

While the engine is turned off the oil will drain from the top of the engine. The Lumina has hydraulic lifters and uses oil to move them. The lifters will "tap" until the oil builds up enough to hold them up. Make sure that the engine has enough oil, that the oil pressure is ok, and that the oil does not need changing. If these are ok then an additive may be added to aid in quieting noisy lifters.

If they are mechanical lifters, then there is an adjustment under the valve cover. If they are hydraulic then there is no adjustment, and while a different weight motor oil or special additive may help the ticking there is not real way to stop it.

Why would you hear a tapping noise when your Chevy cavalier is running?

A tapping noise is generally the result of a bad hydraulic lifter, plugged oil passage to the lifter, or bad tappets. Sometimes just changing to lower viscosity high detergent oil will cure it. Or "Any automotive oil additive with the word MIRACLE in it".

What make your engine knock until it warm up?

Typically vehicles that use hydraulic lifters & have more miles on them, tend to have a tapping sound until the engine is "warmed up." The hydraulic valve train is designed to eliminate the gap at all operating temperatures, though overtime the lifters wear out and don't fill with oil as quickly resulting in the tapping sound you hear until the engine has warmed up, and the lifters have been properly filled and lubricated.

Valve tapping and blue smoke from exhaust no coolant mixed in the oil on 1994 ford probe gt with correct oil level and oil weight?

What cause a tapping noise in a Pontiac bonnieville?

What causes the fuel injector's to tap real load then stop then tap again?

Fuel injectors don't tap. You are hearing the hydraulic valve lifters which are full of oil when functioning properly. Without sufficient oil they will make a tapping sound. If the car has sat for along time they will sometimes tap for a few seconds when you first crank it up. If yours valve lifters are tapping intermediately I would suggest checking your oil level and if that is OK you may have an oil pump going bad. If that should be the case do not drive the car as the motor will not get sufficient oil and will burn the bearings and kill the motor.
