do you mean "why do lifters go bad"?
Well over reeving an engine can kill a lifter. Its a ticking that sticks around usually in between a certain rpm and load.
Some times lifters can gum up and prevent a check ball from seating. this is usually apparent when the lifter makes constant noise of noise just when the engine is cold. A fix for this is using a detergent of some sort like ATF or Sea Foam.
I'm no expert but this has been my findings. good luck.
Not changing the oil often enough

In most cases, you can tell that your lifters are bad, in your car engine, by the ticking noise. A bad lifter will make a tapping sound.
it depends on the car
Usually a "Clicking" sound.
You will hear valve train clatter.
Probably not, a 2001 Windstar usually has hydraulic lifters that never need adjusting it could be a bad valve spring, or a bad lifter that will need to be replaced.
it could be a faulty gage or a bad oil pump
The lifters are in the cylinder heads.The lifters are in the cylinder heads.
These engines would tick if they were low on oil. Try changing the oil and filter and rechecking it. But these engines were also good for having lifters go bad. If the oil change doesn't work, and providing the engine is in good mechanical condition (no sludge build up, etc...) put some lifters in and you should be good to go.
