    And don't forget the little barbell at the back of the block. Just a thought. Really enjoying the videos.

    Enjoyed the video and learned a few things. Good luck running down the oil pressure gremlins;)

      Thanks, hoping it isnt a big deal, but will find out soon. Thanks for watching!

    Along with the usual suspects, pick up tube o ring and cam bearings. Check the oil pump pressure relief valve, mine stuck partly open and I had near zero oil pressure

    On the water pump . . . I always use the paper gaskets -- with no RTV or anything. Always use them dry.

      Whatever sealant was used on this one dried up hard as rock, major PITA to get it off

    A cold LS with worn bearings, you should see at least 25psi for oil pressure upon startup. I think your sump pick up tube o-ring is split.
    I've seen a '07 5.3 with barely any oil pressure and the message center saying to shut it down. It was discovered that the No. 1 cylinder had 65psi for compression. An AFM lifter had seized. The reason? The sump pick up tube o-ring at the oil pump was split. I've had a '09 5.3 with low compression on the No. 7 cylinder with 40psi oil pressure upon start up. It was a seized AFM lifter. This past Friday I have in my shop a '15 6.2 with nearly 45psi oil pressure upon start up with zero psi of compression on the No. 4 cylinder. I clearly have a seized AFM lifter, maybe even a pushrod taken out because of it.

      big reason I stay away from DOD engines is those lifters, if I had one the first thing I would do is do a DOD delete. We will see on the oil pressure soon, thanks for watching!

    Check the oil pump pickup tube. It could clogged. Or just might need an oil pump

    I had a 5.3 with low oil pressure and it turned out that the engine was completely worn out. I put another 5.3 in my truck and now I have 60lbs of pressure!

    • @rust_hoarder_garage
      @rust_hoarder_garage  5 днів тому

      Could be! This one is acting like a small block that pump pickup fell off, so hoping it is just a destroyed pickup oring.

    Oil pick up o-ring. These lifters don’t go bad. It’s a gen 3, failed lifters are the gen 4 “dod” engines

    Great video!
    It would be better if you showed how you connect the fuel system?
    And the size of bit you used to drill the oil sending unit and the tap size?

    • @rust_hoarder_garage
      @rust_hoarder_garage  4 дні тому

      Eventually I will make a video on my fuel system, but it’s just an old Silverado fuel sender in a 5 gallon fuel tank.
      As far as the sender I have no idea what drill I used but the threads are 1/8” NPT, you can look up the drill size for it. More details here.
      LS swap gauge hookup for free, no adapters to buy, electric or mechanical it's the same, easy to do!

    Change the o ring. I just changed mine and now it’s back up to 50 PSI. It dropped down to 7-10 PSI and I stopped driving it until the new o rings came in.

    • @rust_hoarder_garage
      @rust_hoarder_garage  5 днів тому +1

      I am hoping that is all it is, it is acting just like a small block that dropped the pump pickup off.

    If the pickup oring is bad wouldn’t it suck some air? Which may make the oil a little foamy, maybe see it on the dipstick?

    • @rust_hoarder_garage
      @rust_hoarder_garage  4 дні тому

      It would definitely suck in air, just have to see if that is the problem. Thanks for watching 👍

    Great posts, thank you! Is it best to avoid flex fuel LS? Do you explain diy vats delete or is that a separate purchase?

    • @rust_hoarder_garage
      @rust_hoarder_garage  4 дні тому +1

      Thanks, I prefer flex engines for engines that I may put an aftermarket cam in because they have larger injectors. VATS has to be programmed out of the PCM, if you are tech savvy there are free software programs available, otherwise there are many people offering the service. UA-cam has videos on the free VATS removal information. HPTuners is another option but is not free.

    Do the 2 red wires from the harness run to the same lug on the starter? And could you confirm which lug?

    • @rust_hoarder_garage
      @rust_hoarder_garage  5 днів тому

      Yes, they both run to the large upper lug on the solenoid where your positive battery cable connects, usually a 13mm nut on that stud.

    Low oil pressure. O-Ring? Or Barbell?

    • @rust_hoarder_garage
      @rust_hoarder_garage  5 днів тому +1

      Hoping just the pickup tube oring, we will see.

    • @GrandPitoVic

      @rust_hoarder_garage Yes sir!!! That's what I'm hoping. That's the usual suspect!!!

    Plastic timing chain wear blocks fail.
    Best to replace all timing chain components when engine is out.
    Just tearing down a 2019 6.2 broke teeth off cam sprocket.
    $50k Silverado dude didn't change oil enough foolish.

    • @rust_hoarder_garage
      @rust_hoarder_garage  6 днів тому

      luckily no plastic on these timing sets, all steel, nothing like the nylon teeth cam gears of the 1970s. Thanks for watching!

    • @Nudnik1
      @Nudnik1 5 днів тому

      @rust_hoarder_garage Wear blocks on tensioner 6.2 and 5.3 ,6.0 are plastic.
      Chain and gears are steel.

    • @rust_hoarder_garage
      @rust_hoarder_garage  5 днів тому +2

      This is a gen 3 engine, not a gen 4. No tensioner blocks.
