    2025 Yukon XL Denali Ultimate

    Our family owned 5 Suburbans in a row. After our kids were out of the house, I looked into a smaller SUV or a Tahoe. Not much in the way of better fuel mileage and cost so we ended up with two more Suburbans as empty nesters.

    Dreaded Effing lifter tap...... - SOLVED

    I had the same issue with lifter noise. Well serviced 2018 Silverado 1500/6.2 with 80k miles. Turned out that it was a bent pushrod. I had just finished chemotherapy and could not do the repair myself. No oil change or chemical was going to fix this. so I paid $5,000 to have half the...

    DOD Delete Cost

    Cost of replacing all the lifters, etc on one side of my 2018 Silverado 1500 6.2 after it bent a pushrod was $5000. I have heard similar costs from one other person having it done at the dealer. That is here in the Seattle area using a well recommended shop. So comparing that to the cost of...

    AFM/DOD Questions

    My 2018 Silverado 1500 6.2 has had a very mild stumble at idle from almost the day I got it. Took it to the Chevy dealer for a tranny service at 50k miles and asked them to look at the stumble. They said they all do that and not to worry. So I do not worry about it. At 80k, the truck bent a...

    Maybe not all 6.2's have the bad lifter bore/ bearing wear issues

    2018 Silverado 1500 6.2 owner here, with 80k miles. My truck was well cared for, oil changes about every 6k miles (now severe use), using the proper AC/Delco filter and proper weight oil. Did two Blackstone tests, and all was good. Just after 80k and an oil change, the engine bent a pushrod...

    5.3 Guys, opinion on oil change intervals

    I had my oil analyzed by Blackstone and they said that I can do oil changes every 7300 miles. That is almost exactly what my oil percentage meter says when at zero. Truck is a 6.2 in a Silverado 1500. I use the AC/Delco filter and the correct Dexos oil. Typically, I do the change myself when...

    2018 - Skid plate removal for oil change?

    I also have a 2018 with a skid plate. A couple of tips that I use to make it less messy after getting it up on ramps: 1) I use a hole punch and put a hole in the bottom of the oil filter. Get the drain pan under the filter and pull the hole punch out. Almost all the oil will drain...

    Spark Plug requirements making me nuts

    May have answered my own question Pulled the factory plug, and it is an AC Delco 41-985, GM 12571164. I bought the car second hand, but I would guess these are the original plugs. Internet info seems to say these have been superseded by 41-110, so I am going to check that out. Amazed that...
