the other day i noticed a ticking sound. i have a 2002 wrangler. but i have also heard this common. any help? thank you
 

Give us some details first, motor size, last oil change, does this ticking sound near the exhaust, top end lower?
 
Is it all the time or only in the first few min after starting?

Stuck lifter,valve, loose rocker arm,exhaust leak or just the wrong oil filter. Yes oil filter should have a good check valve that does not allow the Oil to drain back into the pan.

Unlikely this
