IOMTT

Same thing. It smells like CRANKCASE fumes to me. 2020 5.3 180,000 mi, uses 2 quarts in 7500mi

Mine pissed out a small amount of gear oil during the 0F weather. Upon inspection, the reason appears to be the vent hose run horizontally, small bellies allowing a few drops of water to accumulate & freeze. Another snowflake engineer fail. You heard it here first.

I got it, ty. 8L89E

WHERE on the case? I see a 1/8" pipe plug

22,000 miles in my '20 Z71 crew cab 1500. It's as if the front shocks have no damping ability whatsoever. At highway speeds, going over a bridge with it's unevenness, it bounces violently 5-6 cycles, pivoting off the back axle. What a piss poorly engineered shock choice. Sucks off-road too. Been the same since new.

OP, you bought the WRONG TRUCK for the intended purpose.

How do we know the engine "can't get enough air" with the OEM setup? Just like crossing a mountain pass at 6,000 feet, the turbo, by design, satisfies the engines ECM commanded boost value by adjusting it's own VNT rack. Any slight increase/decrease in plumbing restriction is easily compensated for.

Wix/NAPA is top quality stuff. Many, many oil filter comparos have been done, confirmed this.

Towing capacity in WEIGHT is deceiving. FRONTAL AREA is where the resistance is at cruise speed. Chevrolet referred to it in their owner's manual towing section in the past. Ever wonder why they show a flatbed trailer hauling granite blocks or a small tractor in their TV ads? Put a 5th wheel camper with the master bed in the front on there.... it will separate the toys from the trucks.

Personally, 1.6 million miles in TDI's with Amsoil. 635,000 on one. Those little engines operate at very high (piston crown/top ring temps) and I towed long distance as well. Similar longevity in my powersports products. Dexos is a marketing ruse.

The farging GARBAGE that GM gets away with selling for premium money. Totally avoidable, just poor vendor quality control, driven by the DESCENDING price scale to suppliers. Pirate bastidds.

Any difference in economy?

Drill & tap a 1/8NPT pipe thread at the bottom to drain. ( or get a friend with skills) I've done it 45 years on dozens of trucks.

That intake shown, takes air from BEHIND the radiator & condenser, which is significantly hotter than the OEM location ahead of the gasketed radiator bulkhead.

These vehicles are engineered with a cold air intake right from the factory.
