    6.6 Gas L8T Engine Swap in 2015 Suburban

    If you wanna get rid of it superquick, feel free to lowball yourself. How many 2015 Suburbans out there have practically new L8Ts in them, just now being broken in, again?

    Partial List of Front Torsion Bars

    @War_Pig, do you still have your SPID sticker? I'm trying to find out which front torsion bars were GM OE for your SSV? 'cause it looks like you could use the adjacent listing as replacements: 15712407 - LH (6WX) (Max torque 5826) 15712408 - RH (7WX) (Max torque 5826) 15528955 - LH (6GF) (Max...

    EVAP I/M Readiness is Going to Be the Death of Me! - Somewhat Solved - Still Alive

    How close can you keep the fuel tank to 1/2 full? Between 5/8 & 3/8 full is best. On a very full or nearly empty tank, the EVAP does not behave the same as when it is between 3/8 & 5/8 full.

    “Normal” oil pressure on Gauge-2013 Tahoe

    Being mildly paranoid, I'd take this as a sign to try an oil change interval of 4500 miles, even if it's clean. Feeling really froggy? Have the used motor oil analyzed to see if it's diluted by something, or just getting old.

    Hoods and body kits?

    Could be wrong, but I don't think the Escalade's fender louvers are actually functional. Hood louvers would be FAR more effective at shedding heat than side louvers.

    Partial update of partial list of torsion bars: 15048307-LH (6XK) (Max torque 4553) 15048308-RH (7XK) (Max torque 4553) 15048309-LH (6XL) (Max torque 4626) 15048310-RH (7XL) (Max torque 4626) 15058265-LH (6YF) (Max torque 4863) 15058266-RH (7YF) (Max torque 4863) 15712407-LH (6WX) (Max torque...

    Yukon vs Tahoe paint

    YES. To prove the point, compare & contrast a Tahoe / Yukon vs an Escalade. How much would it cost a talented body shop to swap out all the Tahoe / Yukon stuff for Escalade stuff? Point is, yes, it'd cost much more time and effort - but FAR less money - to do the above, than to just buy an...

    6.0 Swap Time!

    A 4L80E will never accelerate as quickly as a 4L60E (2.48 vs 3.06 1st gear), and no 4L80E will ever get as good MpG as a 4L60E. On the other hand, whatever the 4L60E saves in MpG over a 4L80E, MUST be invested in rebuild upgrade costs to make it nearly as durable as a basically-rebuilt 4L80E...

    Does a 2024 Z51 with 6.2 require premium fuel?

    If driven hard, if the engine is working or playing hard with 87, the pcm / ecm IS responding to detected knock AFTER IT HAPPENS by pulling timing back, and possibly adding (wasting?) fuel to cool the cylinders. The pcm / ecm NEVER learns this. It never predicts or avoids knock. It only responds...

    Engine failures

    Of course GM has enough money - their profit margins on each suv & pickup truck sold are more than enough to replace each of those engines, even if they're replacing them for free. GM isn't losing money here, there just making less profit than originally projected. That's what they get for...

    Main Bearing Failure with 6.2L at 3,200 miles

    How is a transmission problem, an engine problem?

    Does a 2024 Z51 with 6.2 require premium fuel?

    The difference between 91 octane recommended vs 91 octane required and the gaping chasm in-between, where idiotards expect immunity from any consequences from working/playing hard, while failing to understand or consider the PROVEN FACT that the MpG improvement from using 91 octane always...

    Useless Information

    Does a 2024 Z51 with 6.2 require premium fuel?

    Thought pistons were technically part of the bottom end, but yes, forged pistons would be an upgrade that would withstand knock better than cast pistons.

    SOLVED!!! '96 Yukon Cylinder 5 Misfire

    Replace the spark plugs and spark wires. Under $100 if you DIY, or buy a friend a 6pack of beer and a 6pack of Boylan's Ginger Ale. Also, when you replaced the injectors, did you keep the old ones, or did you give them to the mech?

    Unbelievable engine hour/idle timer

    An EXCELLENT guess. That said: Extraordinary claims not only require extraordinary proofs, they also require extraordinarily detailed proofs.

    Does a 2024 Z51 with 6.2 require premium fuel?

    So, even though the engines (not the cars) have had knock sensors, they still recommend premium. Sure, one of the reasons is likely that the carmakers are being paid to recommend premium. One of the other reasons cannot possibly be, that it actually is better for the engine to use premium? I...

    V4/V8 issues

    No insult intended, but hurry up and disable Engine Half@$$ / V4 mode at your first possible opportunity, then understand it later if you like. Besides the three techniques cited by Geotrash, there may be a 4th, cheaper option; involves disconnecting a vacuum hose, wish I knew more, someone here...

    Unbelievable engine hour/idle timer

    Ol' E Schidt. I earnestly second this motion. It would behoove us all to find out the answer to this question; presently 2016Dom's Idle Hours appear to be literally outside of the realm of possibility ...

    Quaker State Full Synthetic, 1. Which Quaker State Full Synthetic 5W30? Just QSFS, or QSUPFS? 2. Either QSFS or QSUPFS - singly or in combination with the others - 5W30 should be a suitable replacement. In fact I would not hesitate to use QSEFS in combination with either or both of the others...

    Does a 2024 Z51 with 6.2 require premium fuel?

    And/or most people don't drive like their trying to prove anything, except maybe how to drive Miss Daisy. Some NYC livery drivers drive Escalades using 87 AND E85 ... VERY GENTLY, in stop'n'go Manhattan traffic. Then again, they usually turn them in at the end of the lease ...
