Ok so I'm full of questions today, which means I can't seem to search worth a darn. Anway, when my truck is at idle I've got a bearing type noise. Basically it's not from the top of the motor and it's towards the front. It almost sounds like a bad bearing would. It's pretty hard to explain how it sounds and where it's coming from. I can't seem to isolate since the motor itself is so loud. I've wondered if it is the water pump forewarning it's death. The truck runs fine, except for a strange sounding injector that I think is the UVC, but the sound is there constantly at idle, cold or hot it does not matter. In fact I never thought anything about it until my buddy with an 02 asked me about it, and his is much quieter than mine. I just had the oil changed hoping that would quiet it down some but no luck. Any ideas?
