Plymouth Acclaim 92'

When I run/idle the car ( V6 ) I can hear clicking irregular sound coming from timing belt / water pump side of the engine .I notice it about a week ago when the noise was more like something is going against metal guard. By then when I sprayed WD40 oil on bottom big pulley ( serpentine belt ) the sound instantly disappeared. Now is more like irregular clicking and spraying does not make any difference. I visually checked timing belt , and looks fine. Water pump does not leak. After few minutes of running the engine the sound is getting quieter.
I appreciate any ideas.

I own a 93 Dodge Spirit (4cyl) and after 85K miles I would hear a screeching noise upon stsrtup that slowely disappeared after warm up. Replaced all the belts, and the water pump, and problem solved. The problem with waterpum is that even though it may not show leaks the internal bearing could be failing slowly. Also check the pulleys for wear and tear.

Thanks , I hope it is not engine's internal problem .
