    Heads up! P216E, P0300, P0324 all related (New Engine install, New Injector Install)

    I bought the J hook tools, didn't have much luck. The trick ended up being using two pry bars to apply the force at just the right angle to get it out. It was a ***** of a job I don't want to do anytime again soon.

    Heads up! P216E, P0300, P0324 all related (New Engine install, New Injector Install)

    today I pulled the drivers’ side harness (ordered them both anyway, they’ll be here tomorrow. Nowhere near as bad as the p/s one, but the insulation is beginning to crumble. This is something to look at for anyone experiencing a random P0300 code for sure

    Dual Batteries question

    Is there a way to tie the dual batteries together so the truck can jump itself? There's a relay on the firewall that seems like its part of that system, but I'd rather not create a fire experimenting. thanks!

    2015 xl denali - ANOTHER no crank - no start issue! Scratching head!! - SOLVED

    I went through a lengthy troubleshooting process and eventually replaced the main battery's negative cable. I figured if I could jump it from my jump box it had to be a cable issue since all of the battery voltages were good.

    2020 SSV from Chicago motors

    I'm on my 4th truck from them, they're good folks if you're careful with what you pick out. Do your rear doors/ windows work? I had some work to do on mine to get all of that sorted out. Nice to see another NC'er here, looking forward to getting mine back on the road so I can get to work...

    Heads up! P216E, P0300, P0324 all related (New Engine install, New Injector Install)

    Here's a good one for you. I'm in the home stretch on installing a reman (AFM Deleted) 5.3 in my '15 PPV. My son the gym rat bent the RH fuel rail removing it from the old engine, so we replaced it. We also replaced all 8 injectors with new OEM. Removing the fuel rails/ injectors from a 200K...

    IS AFM DISABLEMENT NECESSARY??

    Its still going to have the weaker valvetrain components, but they will probably last longer.

    Deleted AFM/ Deleting the Vaccuum pump

    I'm getting near the finish line on installing the engine, and when I was researching the pre-lube setups, I stumbled across some folks deleting the external vacuum pumps on their L83 engines. With the AFM deleted, there is no real need for the external vacuum source. The reasons make sense...

    What's the highest mileage AFM motor you've seen or own?

    Mine went 193K/ 13000 hours before #6 intake lifter collapsed.

    2018 oil cooler assembly replacement?

    when you pull the rubber collars back, you will see a spring clip in the void that the cover was hiding. A small pick tool will disengage it, then you can pull the lines free of the radiator.

    Idea On Cost To Replace 5.3 Engine? 2015 Yukon XL

    You're going to end up unemployed if you rock the boat on a wholesale purchase from your employer. You won't win. There's a reason they put "as is" on that stuff, consider this a life lesson and move on. (or at least go out spectacularly, lol)

    Idea On Cost To Replace 5.3 Engine? 2015 Yukon XL

    #7 is one of the Active Fuel Management cylinders (#1, #7, #4, #6) so you likely have a collapsed lifter there. Take the valve cover off and manually move your rocker arms on that cylinder to confirm (or have a mechanic do it). Being a couple of months into my engine swap on my Tahoe, I can...

    2018 oil cooler assembly replacement?

    there’s not a tool at the radiator like the coolant hoses and fuel lines. You pull the rubber covers back with a small pick tool, and you’ll see some little spring clips holding the line into the keepers. Carefully pry those out with a pick tool, push in on the metal hose, and then pull them...

    Transmission rebuild issue.

    My PPV has 193K on it, and the trans has been acting up for about 20K miles. A shudder here, a delay there, etc. When my engine went and I pulled the radiator (disconnected the cooling lines) I smelled the burnt fluid and decided to rebuild it. I pulled the trans off of the transfer case and...

    Coolant Temp Sensor lasts about 30 days

    Is it possible you have a marginal ground maybe? Perhaps you have a sensor going out of spec as it gets a few days on it because of the ground? That’s an interesting one for sure.

    Worthwhile dealer add-ons?

    I did a 10 year sentence in the car business. We call the addendums “sucker stickers.” However, after the Covid debacle/ supply chains, the dealers had the upper hand for a bit, and these addendums became a “take it or leave it” tactic and unfortunately supply and demand won, and the dealers...

    code P0307 and C0561-71

    Don't rule out the lifter collapsing. Mine did it and it didn't make an obvious noise. Pop the valve cover off and move the rocker arms and you'll know for sure.

    Afm

    Mine made it to 190K with regular maintenance until the #6 intake valve lifter collapsed. If you’re planning on keeping it over 150K miles, I’d plan on having to deal with the issue eventually. I’m installing a reman that I had built without the AFM components, and I had my computer...

    PPV and SSV - AFM and DFM

    Just to update this. Right after 190K, my Tahoe had a P0306 when I was driving to lunch, and an obvious misfire going on/ dead cylinder. My AFM system failed on the #6 intake valve, collapsed lifter. I’m in the process of replacing the engine with a reman.

    2001 Tahoe 4wd theory

    Is there a servo/ actuator of some sort on the front diff? Assuming it gets power from the transfer case?

    2001 Tahoe 4wd theory

    Interesting. That would be the easiest solution. Is there anything going on at the front axle as far as engaging the “hubs” or does it all happen at the transfer case?

    2001 Tahoe 4wd theory

    Thanks for the input everyone. My son and I are dropping a K5 Blazer body onto a 2000-2006 Tahoe chassis. I’m going back and forth between customizing the heck out of the wiring and ancillary systems, or just using all of the Tahoe wiring/ components and going with a custom “retro” type dash...

    2001 Tahoe 4wd theory

    Is there anything that happens with the front hubs/ differential? I’m wondering what “tells” the transfer case and front axle to lock everything in 4wd.
