Hey all I'm wondering if anyone has experienced anything similar to my ordeal? So I have a 2020 GMC Sierra 1500 5.3 V8. It only has 1500 miles on it and we just pulled our camper with it which only weighs 4500#. It pulls fine doesn't squat much and I use a weight distribution hitch. We took it to the campsite unhooked and I parked the truck. The next morning I started up the truck and the service engine light came on. After about 5-6 starts it cleared and is no longer on. It seemed to drive fine even when the check engine light was on. I'm wondering if me parking the camper going forward and reverse a few times made the gas mileage so bad it triggered the warning light?
2019 Silverado 1500 z71 with 8K miles, 3.23 rear, 8 speed.
Today I have towed about 8000lbs of cattle and trailer. I prior towed an old farmall tractor back.
Both times when towing over 6000lbs, I had the transmission in L6, tow haul mode. Sometimes when taking off from a stop, it almost felt like the truck started in 2nd, not dropping down the first. Would it do that? Or is the torque converter just being floated as RPM's rise, and possibly I am not feeling the shift from 1 to 2. This transmission is crazy smooth compared to my 6 speed.
Truck drives great otherwise. Ran it to town empty later, no issues. Even ran it thru the Low mode gears, and it starts in first normally. Thought maybe this was towhaul mode trying to avoid unnecessary shifting if still rolling. Transmission running cool, never over 180 even with that load at 60-70 mph.
Thanks for sharing your experiences.
Currently working on a 6.0L V8 (2000 LQ9 I believe) and cannot seem to locate the PCV valve and hose (see image for reference).
I was under the impression that they weren’t integrated into the valve cover until around 2005. The body of this truck is a 2000 Sierra 1500 but the engine was replaced from the 4.8 to the 6.0 at some point so I’m guessing for a lot of the component locations.
First time poster, any helps appreciated.

I'm trying to update an old 51 pickup that hasn't run in years. What's the most affordable way to put a newer engine in it? I was thinking something like a small block, but I'm out of my depth.
The end goal is a dessert runner, mild offroad capability.
