Knocking TJ

Whats up yall i just got a 97 Tj 4cyl. THe jeep has 117k on it but the engine has been rebuilt. At idle there is a tapping sound coming from the engine and i noticed that my oil pressure is dropping out. When i am driving down the road or idled up the tapping stops. Help

well the oil pressure dropping is normal once the oil warms up and you are idling but i dunno bout the tapping sound, Does it sound more like lifter/spring noise or piston slap?
