engine chirping noise

KB281JD · December 18th, 2009, 10:58 PM

hey wondering if anyone has had a problem like mine. i'm getting this chirpping noise coming from the engine on start up, it usually goes away after a few minutes. i have a 4.6 2v with a kenne bell 2.1 big bore. my first hunch was one of the idler pulleys but now i'm thing either the tensioner or alternator? i've used my stethiscope to try and hear where its coming from but no luck

thanks guys!

take the belt off, start her up, and see if the noise goes away. if it does then you know where to check, if not then you know its something else.

i know that its coming from up front somewhere, like when i rev the engine the chip gets faster. (it really sucks to take the belt off with the Kenne Bell kit) i'm wondering if the KB is putting too much tension on the tensioner and thus ruining the tensioner bearing?

could be, ive heard it happen before on another board. is it the same through the revolutions or does the sound change?

same, just speeds up.

i cant remember the forum that I was on where I seen it but they found it to be the tensioner. Its either SVTP or Corral.
