  1. What was the song and dance to get the engine replacement? I had all 16 lifters replaced last week and the CEL is back on.
  2. I'm in the same boat, had all 16 lifters replaced last month and now the CEL is flashing again.
  3. 2021 GMC Sierra 5.3 3800 miles. Had all the lifters replaced per TSB. After 100 miles the CEL is flashing again. Whats the next step? Engine replacement?
  4. I watched a video on YouTube that showed Amsoil losing to Supertech in a motor oil test
  5. Watch "Silverado leaf spring clunk temporary fix" on YouTube https://youtu.be/hMy-oQIPNuQ
  6. Drive it until it blows up and then take to it the dealer.
  7. This post is old AF.
  8. This is what i did for a temp fix.
  9. Here is the video
  10. Took mine in today 2017 Silverado Z71 , they said thier was not a fix. The tech showed me how to duplicate the noise. He started to shake the bed of the truck left to right and the truck started to clunk. He said it was the axle shafts beating around. He also showed me on a 2019 trail boss. LOL
