Jeep liberty 2006

while driving and accelerating a tapping soud is occurring. vehicle has had oil changed within the last 6 weeks. new belts and belt pulley has been changed in the last 6 weeks also

vehicle seems to run okay. tapping does speed up when accelerating

Can we assume that you have checked your dipstick, and verified that there is sufficient oil in the crankcase?

How often (both in odometer miles and elapsed time) do you change the oil?
What type of driving do you normally do? Just local, mostly highway, mixed?
How long have you been hearing this noise?
