What would make a tapping noise when vehicle is turned on then noise quits after ten minutes?
1. One or more lifters in the valve train system may be stuck in the compressed position due to sludge or other buildup from less than optimal oil change periods. As the engine warms up the combination of heat and warm oil softens the buildup enabling the lifter to expand and remove any slack in the valve train.
2. One or more lifters and the camshaft may be worn past the expansion limit of the lifters thus creating slack in the valve train. As the engine warms up the parts in the valve train, primarily the lifter and push rod expand and remove the slack. This type will eventually wear past the limits of expansion and become continuous tapping. Again this may be cause by less than optimal oil change periods. If the onset of tapping was shortly after an oil change where the engine had a "cleaning treatment" performed, the cam and lifters were probably severely damaged during the treatment. Engines with such damage may continue with little or no additional damage with proper maintenance however there is no guarantee. 3. If the tapping is very light, as opposed to the louder, heaver sound of lifters, it may be the fuel injectors. These always make some noise but as the engine reaches operating temperature the noise usually decreases to the point it is obscured buy the other noises from the engine.

If there is a knocking or tapping noise in a 1995 Firebird with a slight ping that is not coming from the engine and it only happens when you press the gas could it be that the u-joints are worn out?
U Joints can certainly make noise after they've started wearing and are dried out. If you have concern about an unfamiliar noise, take the vehicle to a trusted mechanic or even the dealer. It's nearly impossible to tell you what the noise would be from a description like that. Read More

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. Read More

You don't... Hydraulic tappets are fitted. If they make a tapping noise occasionally that goes away get used to it, or add hydraulic tappet cleaner additive to the engine oil after an oil change. If they constantly make the tapping noise it's time to get them checked out. Could be expensive! Read More

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". Read More

If it is a Tapping sound it is normally a lifter. Could also be a cam, pushrod, and or a rocker arm. Tapping is normally upper motor. If it is a knocking noise it is normally in the lower motor. If the noise gets louder when warm most likely a lifter is going bad. As the oil heats it thins slightly causing more oil to bypass inside the lifter which it is not supposed to… Read More
