I have the same motor in my 95 cav. it does it, i think its a lifter, but my aunt bought a 2004 cav. it started tapping at 24,000 miles. mine has over 175,000 on it. sorry i couldn't be of more help. Tim
I also have a 95 Cavalier with a 2.2, and the car has made a disturbingly loud tapping since I bought it 3 months ago. Last week, the tapping became louder and constant, and about 10 miles later, it stripped the timing gear. The mechanic said that I had a sticking valve, and that 2 pistons had not been firing for some time (I'm sort of upset with the shop that performed a tune up 2 weeks ago, You'd THINK they'd have noticed!). You might want to get it checked out. Oh, it DID last for 240K miles. Steve
Engine rod? Engine bearing?
The loud tapping sound can be caused by a complete heating of the engine. Worn tappets can also cause the tapping sound.
that year had the jet engine option
It turned out to be the alternator going bad. Replaced alternator. No more growling.
chances are good in your 1996 Chevy lumina if there is a slight tapping noise, check the oil. it may be low, or you may need to add a thicker additive. good luck!
The 2001 Chevy Cavalier may need a valve adjustment. Loud valves tend to create a clacking noise which could mimic popcorn popping.
A tapping noise might come into the engine because of heat damage to the lifters of the motor. You might also hear a tapping sound if the engine has been damaged due to a blown head gasket.

The audible warning sound, for your 2000 Chevy Cavalier, can be fixed by replacing the sounding device. The sounding device can be purchased at most auto-parts stores.
Sound like your fuel/air ratio is not correct.
The noise has been coming from the engine for the past week and I have been told it might be the oil pump not providing oil to the sump. The tapping sound comes from the engine and increases when i change into a higher gear and drive faster. Please help!
If the ticking sounds like a "normal" ticking, it is probably the fuel injectors.
