Hey Yall,
I need some help figuring out what is the source of a loud noise coming from my engine. To give a short background, my truck (daily driver) has sat for almost 4 months. I was gone on a deployment and got back a couple days ago. I noticed that whenever I hit the accelerator there is a loud noise that gets faster as I hit the accelerator and accelerate. I figured it had to be a pulley or the belt, but the belt is fine from what I know. No cracks or anything like that. I replaced the tensioner and idler pulley but have had no change in the sound. I even had a spare belt I keep just in case and changed it to that but the sound persists. Then I out some belt lubricant stuff since I thought maybe the dust and grime build up of just sitting has caused the noise, it helped for only a short time and the noise came back. I took the belt off and revved it and I have no noise coming from the truck, so it has to be a pulley or the belt. I also spun each pulley without the belt and didnt hear anything. Need some help figuring this out cause im at a loss. Its a 1997 chevy silverado c1500 5.7 V8. Any advice would be great as to where I need to turn to next. Thanks
