acklac7 Posted February 3, 2004 Report Share Posted February 3, 2004 I was reading the service manual and happened to come across the section about timing chain and sprocket noises. It says that the most common noise is a high frequency light knocking sound. I think I have noticed something like this, its like a loud high pitched (REALLY high pitched) ringing sound, but it only occurs at certain times (mainly at start up and shortly after) I mentioned it to the dealer about 2.5 years ago and they said they couldn't find anything....but I have reason to belive they are incompetent.....any ideas? also I when I am in park I put my hands on the steering wheel and I can feel a "thud thud ..........thud thud ...........thud thud .....is this a knock? If so its been around for a while....and I have had a deep carbon cleaning done twice so I don't think its carbon build up...thanks. A.J. Link to comment Share on other sites More sharing options...
Abrankod Posted February 4, 2004 Report Share Posted February 4, 2004 Also remember to check the little water pump belt which is overlooked by many people because its under a little cover. -Dan Link to comment Share on other sites More sharing options...
acklac7 Posted February 4, 2004 Author Report Share Posted February 4, 2004 Thanks Guru, I will check tommorow for the problems you listed....also wanted to run something by you....Last time I inspected the belt tensioner/belt I noticed that when I tightend the bolt on the tensioner it got real tight, but kept turning, It seemed like the treads may have been stripped...if the threads are stripped would this present a problem? thanks A.J.

Takes VERY LITTLE to strip those threads! I was tightening slowly with a 1/4" drive ratchet, and thought I was just turning through some grime in the threads, but I think the threads stripped. It's been that way for over a year and close to 20k miles probably with no issues. If Guru recommends using a tap and a larger bolt, I'll probably "fix" mine.
