No F-bdy Bs

My truck rarely sees a dusty, dirt road, if ever. Actually, never. Within 6mo of ownership, mine was totally covered with road dust and yellow, Louisiana pine pollen. I swear, it looks 6yrs old. You'd think it was an oilfield, or pipeline service truck. Did GM just do a piss poor job of sealing the bay? Anyone else with this issue?

As a l8t owner, I don't think I'd ditch my 7.3 Zilla to get one. Nothing against the 6.6,but the Zilla's issues are pretty few and far between. Yeah, early ones had cam/lifter delam issues, but from what I read, that's all been sorted. Buying new, I'd say flip a coin, as both are solid, but doubt I'd trade my Zilla for a l8t over delamination fears. Honestly, I don't think you can go wrong with any current HD gasser, even Ram. They have hands down the best trans, and the 6.4 Hemi doesn't have nearly as many "tic" issues as the 5.7s. Good time to have a gas HD. Fwiw, my 25' 6.6 with 8,000mi uses basically no oil.

Worst factory HD wheels GM makes

Any 37 lin tire + wheels is adding a considerable ammt of unsprung weight, regardless of the height difference, so I stick to my mpg estimate. Also, front and rear gear swaps are probably pushing $3k after labor.

Diesel or gas? The 37s will obviously, drastically reduce mpg, but the gasser will take a bigger hit to mpg, and power. Rough guess, but I'd estimate at least a 2mpg hit on the diesel, and up to 4on the gasser. Maybe more. I wouldn't sweat a gear change on a duramax at all, and unlikely on the gasser either. You're obviously not concerned with acceleration or towing, and the 10spd will find itself in the right gear without much hunting, if any. If towing, mpg and acceleration are a concern, you're doing the wrong mods. Either leave it alone, or do the lift/tires and let the chips fall where they may.

I'd go right back to the dealer. If I didn't get satisfaction there, I'd go to a different one. If not there, I'd contact GM. It's under warranty. It's their issue to fix.

A lot of people also forget the old 6spd was pretty good at the torque converter snout wearing into the front of the trans case. Pretty common issue. 6spd was not a perfect trans by any means.

Yeah, some "tech" likely serviced it to the Duramax specs. Probably has the wrong oil in it as well.

I think you'll be happier with the 10spd. Real world issues are actually pretty rare dispite the hype Nate puts out.

I wish more tires were offered with raised, white lettering on one side.

That's honestly the first time I've heard of a 6.6 doing that.

Also, egg shaped crank journals, and flawed designs don't help

Got a feeling someone is confusing the 6.2 for the 6.6.

Basically all that. I THINK I may have checked it at some point after the 2nd change , but wouldn't swear to it.

That's not even remotely true. There's literally no cases of out of spec 6.6 gas blocks.
