I have a noise under the hood of my S10 that appears after the engine has warmed up. I sounds liker a "clatter". Its seems to track engine RPM. I've listened under the hood, and it sound like it is comming from the front of the engine. The pickup runs fine, and I haven't noticed any perfomance decrease. However I am a little worried since I can't seem to find the source. Could this sound be comming from the valve train?
