    Lost the 6.2 (was: May have Lost the 6.2)

    Since you are bringing up polymers, I also wanted to point out a future threat... watch out for PFAS regulations.. it is biting the semiconductor industry now even though the regulations say "doesn't apply" to electronic components. Reason why its biting us is because everyone is worried about...

    Lost the 6.2 (was: May have Lost the 6.2)

    This hits home for me. I have always worked for semi-conductor (OE) manufacturers, and all the chip assembly factories are in Asia. I am not sure what GM's true rationale for not letting these teams travel, but assuming its travel cost and impact on bottomline. Depending on the quarter at Wall...

    Lost the 6.2 (was: May have Lost the 6.2)

    just saw this on the main L87 thread... wow.. that's a good chunk of change... I'd have a good mind to ask for a refund or credit given that it was not what your engine needed clearly at the time. ("PICO test" didn't do its job) but its not the dealerships fault so I get it that they may not be...

    Lost the 6.2 (was: May have Lost the 6.2)

    Wow, just saw this... I thought 0W-40 was the miracle oil... I hope for the sake of the others that passed the pico test and running 0W-40 that yours was a one-off ... either the pico test passed by razor thin margin, or something was not done correctly at the last oil change at 43,200 miles...

    Should I buy a 2026 Tahoe Z71 with 5.3 Engine?

    Recommend 5.3L engine all day long (even before the 6.2L "manufacturing defect" fiasco). The ~50-60ft lbs added torque isn't persuasive enough given that the 6.2L needs premium gas (and now premium oil?). Now, 5.3L vs 6.6L, that's a different story.... but unfortunately the 6.6L isn't an...

    2025 Tahoe 6.2-liter Z71 engine light flashing, stuttering engine

    Would be interesting to see what the outcome is... With the 6.2L, just because its a 2025, I wouldn't rule out the infamous crankshaft "manufacturing defect" that affected 2021-2024.. They really need to run the "picoscope test" to rule out the possibility of that kind of problem. We've seen a...

    Project Carbon Next Gen 10 Speed Valve Body Kit - Finally Installed!

    Did you mean to say the GM ones ? Mine should be considered HD as it is on a F350, and it starts off in 1st always... which I also dislike. It is too much of a granny ratio on my 4.3 rear axle and shift to 2nd happens before it approaches ~5mph which I think ends up hurting the get up and go.

    Project Carbon Next Gen 10 Speed Valve Body Kit - Finally Installed!

    Will watch but empirically these 10 speeds seem to not be fuel efficient vs. the 6 speeds they replaced. On my new super duty, I can actually see the gear shifts displayed and every time I take off from a stop sign it hurts to see it go from 1-9 before 35mph…. Seems like a lot of shifting and...

    BREAKING: GM is officially recalling the L87

    If that's all there is to it, great... as I'd hate for info to be missing. Coming back to this thread after a hiatus, apologies for not realizing that. It looks like the oil wars are still going on, now there is a third weight in the mix ? 0W-water vs 0W-40 vs 5W-30 ?

    BREAKING: GM is officially recalling the L87

    The pages were getting too unwieldy and it almost looks like the work of Thanos, as almost exactly half the pages are gone, lol

    Project Carbon Next Gen 10 Speed Valve Body Kit - Finally Installed!

    never mind.... I misspoke, I should have gone back and checked.... but these may not be TTY bolts (didn't make sense ever)... I went back and looked at this pic which shows that there are only 3 bolts to be replaced BECAUSE they have sealer on them.... I'm sure a sealer like Loctite PST would do...

    Project Carbon Next Gen 10 Speed Valve Body Kit - Finally Installed!

    Why did they need to use TTY bolts ? Seems like overkill. Honestly even cylinder heads shouldn’t need them, but fine, with aluminum heads and higher compression ratios maybe there are reasons. We did just fine with standard bolts for over 50 years on valve bodies.

    Fuel efficiency drop in newer models ?

    Fuel efficiency is just about gone with the 10-speeds I swear. Our 6 speed equipped 2018 got significantly better fuel economy, the 2018 and the 2024 are a lot closer in GVWR, etc. The 10-speeds were probably developed for towing, the 2024 does exceedingly well in towing my car hauler. If only...

    BREAKING: GM is officially recalling the L87

    What's this bit about insurance not covering in case of an accident on a vehicle that's been recalled ? Truth or TV sensationalism ? Go to 1:30 in the video below

    New oil change price at dealer!

    Yikes, engine replacement costs are likely amortized in that $152
