Icon5 motor ticking at idle

i just bought a B4000 the other day and now i have a tick sound coming from the motor at an idle. sometimes its louder sometimes it is softer and i can only hear it when it is either in park or at a dead stop and the RPM's drop below 1000. it doesn't effect the way the trucks runs, it is just annoying. could it possibly be that i need to do a valve adjust or do you have any other ideas?

thanks for your time
-Ethan

sorry left that out its a 1998 mazda b4000 auto. it has 170000 miles on it and the guy said that the transmission was rebuilt about a year ago. the noise is almost like a rattling coming from the motor. i was wondering if anyone else has had this problem or has any ideas what it could possibly be.

I have the same sounds coming from a 2000 Ranger 4.0 litre V6. Two ford techs. have said it is normal and just drive it. Mine is a "rattle" or clicking and is quite loud until the motor warms up then it quiets down alot but still "clicks" like a tappet or piston slap. I would also like to know what it is?
