    2014 Chevrolet Silverado LT 5.3 4x4
  1. Thank you. I’ll try the chalk trick this week. I bought extended warranty with this truck but I’d like to be able to narrow down the problem before I get it checked when and if I need to.
  2. Would piston slap go away after 20 seconds?
  3. Here is a better video recording the sound on start up. This was taken first thing in the morning after the truck at all night. Once it warms up the sound goes away Any help would be appreciated.
  4. This is my first post in this forum so please forgive me if I posted it in the wrong spot. Any help with this issue would be greatly appreciated. I purchased a used 2014 Silverado in January of this year. It has approx. 90 000 Kms( 55000 Miles), it’s a 5.3 LT 4x4. I absolutely love this truck, but have noticed a noise when starting lately. It usually happens when the truck has been sitting overnight, or at least a few hours. At first I thought it was a belt slipping slightly, but after a month has passed I believe the noise it’s getting worse. As soon as the engine starts to warm up a bit, the noise goes away. Sometimes I’ll notice a little chirping when I accelerate slightly, but after a few mins of warming up or driving it goes away. I’m thinking this has to be something belt related, a tensioner perhaps? Any help or suggestions would be greatly appreciated. Thankyou Here is the link to a video I took which may be of help:
