Dave's Auto (custom engine builder) tear down of L8T

This guy is a custom engine builder, both diesel and gas. He recently posted this vid of a tear down of an L8T for rebuild. Seems to like a lot of what he sees We Tore Down GM’s Biggest Gas V8… Here’s What We Found It's a bit of a long video, bottom line it's a very well built engine but in this case, excessive heat in the rear cylinders can be a problem.

  I wonder what I'm doing wrong whenever I hear people say they "don't even feel it back there" when towing 10k+ lbs. I could even feel my old 3,500lb travel trailer. Oh well.

  I just brought home a 2020 GMC 1500 Denali. She has 53K miles on her and I want to change out the fluids over the next few weeks. I see the diff covers don't have drain plugs. Any suggestions where I can pick up front and rear diff covers with drain plugs? Thanks, Bob

  Well, the dealership got the compressor and installed it. Air at the vents seems nice and cold as it should be. The service manager said the repair has a two year warranty and unlimited mileage. Hopefully I don't have to use it. The dealership i went to was one where I bought my 2014 half ton silverado. In 10 years and 168k miles on the truck anything I needed done and two small recalls they were always very good to me. Not a huge dealer either. I think they treat people well because they want you to come back. I have dealt with a different dealer that was too big to care about an individual. Just my two cents.
- Multigate Connector Difficult to Connect Fully
  
  By Another JR · Posted 2 hours ago
  
  Hi All, I operate my 2021 3500 SLT most of the time with the tailgate off and in a crate because I have a slide-in camper. However, at least once a year, I take the camper off and put the tailgate back on. Recently I installed the tailgate, but had a hard time getting the connector bail to swing to the fully latched position. The connector seems to fully seat, and everything works, but the bail doesn’t swing to fully latched position. It swings almost there but stops and I am afraid to push it any harder. Does anyone have any advice on cleaning or lubrication or anything else I should be doing? i know how to properly operate the connector. During the time the tailgate and connector are off, i have a double plastic bag over the truck connector secured with rubber bands to keep it clean, but it still had some dust in it this time when I blew it out with compressed air. I didn’t want to spray it with anything other than air without doing some research. Thanks.
