Unless your engine idles for extended lengths of time, or works or plays HARD, there's no need for any engine cooling provisions ...- Marky Dissod

Benefits of the diesel?
On a drive from Breucklen to Suffolk County Lawn Guyland, the price of premium and diesel vary significantly. Some places they're either very close, or the same, depending on when. Some other places, diesel is clearly more expensive, always. But the further away from Queens, the cheaper diesel...- Marky Dissod

2017 Escalade versus 2016 Tahoe for Towing
3.73 would make your Tahoe an even better tow rig. SUVs got 3.42 with NHT, but pickup trucks with NHT got 3.73. Since you're not buying the Escalade.- Marky Dissod

Replacing 6L80E Transmission - What Torque Converter?
There is at least one torque converter that the 6L80 & 6L90 have in common. Ddifference is in the GM OE 'tunes'. 6L80Es are tuned for inoffensive shift feel. TCC slips a wee lil bit to mask any V8 - V4 - V8 sensations. 6L90Es are tuned for towing / hauling very heavy loads. TCC engagement &...- Marky Dissod

Good cam?
The answer to this question really depends on how you are willing to prepare the rest of the valvetrain.- Marky Dissod

Oil pressure
And no one got an @$$ whuppin'? There may be 'something' large enough, lodged close enough to the oil pressure sensor, to corrupt its readings. I'm also wondering about an O-ring ... someone not as tired as me will do a better job of either explaining what I mean, or correcting me.- Marky Dissod

2017 Escalade/Denali L86 "requires" 93 octane - your experience?
Since you are getting your ecm tuned: be sure to inform your tuner that you'll prefer 87, except when your engine must work or play hard. Every pcm and ecm since '99 has had 2 separate spark tables - High Octane & Low Octane. To oversimplify, if your tuner reduces timing in the Low Octane table...- Marky Dissod

2017 Escalade/Denali L86 "requires" 93 octane - your experience?
Best answer I can possibly give: depends on how you drive. The more gently you drive, the more you can get away with using 87. I said 'get away with'. That runs kinda parallel to what GM said: "Use premium 93 octane unleaded gasoline in your vehicle." "Unleaded gasoline with an octane rating as...- Marky Dissod

Main Bearing Failure with 6.2L at 3,200 miles
Do you know Tyler Durden? Asking because the above sounded (to me) eerily similar to Tyler Durden explaining his job as a 'recall coordinator'. His job was to apply The Formula - should we initiate a recall?: "Take the number of vehicles in the field - A multiply by the probable rate of failure...- Marky Dissod

2002 Yukon XL 2WD 5.3L SLE, stock tires were roughly 30.49"...current tires are roughly 32.8" Load Range E.
Read my sig. Went from 32" tires to 29.57" tires - or, from 0.4" taller than civilian OE, to about the same tire height as a PPV. Unfortunately, I did NOT buy sticker, better-hustling 'performance' tires. So now I've a smaller contact patch that is EASIER to fruitlessly spin, so when the light...- Marky Dissod

Which Gas Grade to Use for the 5.3 Engine
Reason why this ol' skool thinking is out of date, is that 11-to1 static compression fails to account for any of the following: the 'hottest cylinder' is no longer #7, it's #1 - except #1 is now closest to the H2Opump there are no exhaust valves adjacent to each other improved quench better...- Marky Dissod

Are all the gasoline engine issues just on the 6.2?
If, every time any powertrain part failed before the powertrain warranty expired, the people who've no clue how to physically build the part(s) that failed, yet signed off on those parts / assembly techniques, starred in a yew2b video of them getting a swift kick in the arse, there wouldn't be...- Marky Dissod
