I'm not really sure if I can say it is an engine noise or a possible pulley noise. The engine is very quiet except for one moment in its run. The noise seems to come from the front area of the block (Belt side). During moderate acceleration all is quiet until just before the trans shifts to second. It only lasts about 2 seconds. I at first thought it was knock but with the windows open yesterday I don't think so. It actually sounds like how a bad harmonic balancer sounds at idle (marble like). Kind of sounds like a bearing noise of sort, almost like something (crankshaft) is spinning out of control momenetarily. I know it might be tough from my discription, but any ideas? The car is quiet except for this moment and the trans and engine run smoothly.
The only dumb question is the one you didn't ask!
