No F-bdy Bs

I've seen a scant few YT vids on them, but it's always in a performance application.

No clue. Service advisor said he'd call me this morning, which I'm 99% sure won't happen. They had the truck 5 days, and I didn't hear a peep. Finally had to call them yesterday. I guess they'd be content to just let the truck sit in perpetuity.

Apparently, its a Brake Module of some sort, which is backordered with no ETA. Thanks, GM.

I'd like to know the year of that 7.3. If newer, say 23'+ I'd be concerned that ford hasn't addressed the cam/lifter delaminating issue. Odd that the 7.3 they tore into died of the exact flaw we've heard about. From a robustness standpoint, both the 7.3, and 6.6 are absurdly overbuilt.

So, what's the issue with the WIX?

Got this yesterday out of nowhere. Truck is a 25',6.6 gasser with 8k miles. Only semi anomaly is that the truck had been sitting, uncranked for 6 days. Elec Stability Control showed immediately upon cranking, not while driving. No drivability issues, just the message. Battery didn't seem to be weak when cranking over. I drove it, killed it, let it sit a few hrs with no avail. Truck is 100% stock. No damage.

Like I've said before. Di and Carbon buildup is not that big of a concern. Engine had minimal buildup, and that engine was obviously not super well maintained. Do regular oil changes, and you're gtg as long as the rest of the truck lasts. Also, the High Pressure FP that people ****** about, but can't tell you why. Now, I wish they'd trash the variable oil pump. No real world issues with them, but I'll gladly eat whatever miniscule MPG it's saving me in favor of more oil at all RPMs. Curious to see his assessment of the 7.3 compared to the 6.6. I expect he'll praise the port inj, but from a structural standpoint, the 6.6 is as robust as any engine out there. Not to take away from the 7.3. I feel it's equally as good as the 6.6. As to heat on the rear cyls, I'd have to see numerous examples before I'd say it's an issue. Especially not knowing the history of that engine. For all is known, they could have blown a rad hose, and ran it hot, and the 2 rear cyls may be the first to get hot in a low coolant situation, but not be an issue aside from that.

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.
