    Blackstone UOA

    Recently changed my oil and decided to send it in for analysis, here is the result. I am pretty happy with it, given the oil consumption problems I had previously. I wanted to get it checked as I had no idea if the consumption issue had caused internal damage and if I was sitting on a time...

    New guy - first Tahoe

    Welcome! Great to know that there are high mileage ones out there. Maybe there's hope for my 07 Yukon which has about 80k miles. Any idea if it has had any of the common issues with these motors such as lifter failures or oil consumption in its history? I see a lot of posts with these issues...

    2008 Chevy Tahoe 5.3L Engine "Upgrade"

    How is it running now, after new plugs and so on? How much oil have you been burning? I was headed down a similar path, but surprisingly, my motor seems to have been salvageable. I never did a compression test tho, and 40 psi, is well, really low. Anyways, here is my link, some of the things...

    Your towing pictures

    My '07 Yukon with 5.3, 4.10 gears and heavy duty trailering, towing its max load, a 32ft Coachman travel trailer. And then something a little lighter, my Victory Cross Country as we were leaving for a 4,500 mile road trip. The Yukon is a surprisingly good tow machine with these gears.

    07 Yukon Oil Consumption, making progress?

    Just an update, 3,000 miles in on this oil change (job change and not putting as many miles on it since our road trip this summer) and it was down only by about a half quart. I was previously using that in 500 miles, so I am still very happy with the progress. Here is the result from the...

    New rings and pistons

    Here is a link to my thread where I cover what I did to improve oil consumption. So far, things are working out real well, and oil consumption has basically stopped or been dramatically reduced. I am nearing 2,000 miles on this oil change and it is still full on the dipstick, although it is...

    Deciding on towing upgrades.

    I have an '07 Yukon XL with the 4.10 and tow a trailer weighing in about 8,000lbs. I love the 4.10, really makes the most out of the 5.3. It does pretty well towing this around, granted our area is not that hilly. However, a quick drop to third, and I am turning 2700 rpm at 65 mph, and it...

    Rough Idle

    Cant help on the rough idle, but my 07 used to dim the lights under other high-load events such as anti-lock, traction control, etc... The battery failed a load test, dropped a new one in and it solved the problem. For the rough idle tho, are you going through any oil? If so, plugs and other...

    AFM Problems

    The instant fuel economy readout on the DIC shows whether it is running in V8 or V4 mode. (I know it was only reading 9mpg at the time but I was towing a 7000+lb trailer)

    AFM Problems

    Mine didn't shudder like yours, but I disabled it because of oil consumption issues. After doing that and a few other minor things, my oil consumption has stopped. I also got much better throttle response and improved engine braking. To summarize what I did: - Range AFM delete stopped the...

    Wife Hits the curb!!!! RANT

    Like others have said, stuff happens. Wife curbed ours on one that had just been painted as a safety crosswalk, you know with the orange/yellow paint? It was ground into the tire. Even though I did my best to get it off, I could still notice it when the tire was eventually replaced for wear...

    07 Yukon Oil Consumption, making progress?

    All I can say is WOW!!! I was only hoping to help manage oil consumption, but it now seems that the oil consumption has COMPLETELY STOPPED!!! http://www.youtube.com/watch?v=TpF72tUXW5w 1000 miles into this oil change, which includes 400 miles of heavy towing, and NO OIL USAGE so far!! This...

    07 Yukon Oil Consumption, making progress?

    I use Seafoam in the gas cans for my power equipment and run it through my motorcycle once or twice a year, all with great results. But using it through the booster? I assume you are unplugging the brake booster and what, sticking it in the seafoam can to suck seafoam into the intake? Is that...

    AFM Disabling module question

    I honestly was starting to believe my engine was on its way to being toast. But I am starting to think that this might come around, and I think the AFM disable is a big part of the equation. So, if you are thinking about it, I say go for it, as long as it is turned off you will be in much better...

    07 Yukon Oil Consumption, making progress?

    It is the 5.3, and I am hoping to get a lot more miles out of it. They are great trucks. I hope you have similar luck with yours. The only concern I'd have is if the truck is a higher mileage unit, will that make a difference. I do think that multiple approaches are necessary to reduce...
