Sounds strange I have 2018 Silverado V-6. The fuel pressure sensor went out. The service tech then stated the system needed the Direct injection Service and the upper valves and everything was in need of this service. The truck has 42,000 miles on it. I purchased used with 32,000 miles.I couldn't believe the price tag on this service. 

I almost said no, apparently the Direct injection engines need this to be done. Do they make it so that the more advanced the emissions the more often and delicate these trucks have gotten. Did I get taken advantage of?

At that low of mileage that service should not have needed to be done. I would have wanted proof that they were actually in need of cleaning first before paying for it. These engines are known to have build up on the back side of the intake valve and the intake runners because they are now direct injected but I see that more will neglected vehicles. Changing the oil on time, clean air filters are key to stopping build up.

 

I took the intake off my truck at over 100,000 miles and had very little build up, it did not worry me one bit. They sell a do it yourself intake valve cleaner kits at autoparts stores and even the GM dealer, those can be performed every "X" amount of miles to help as well.

      This is a really late reply but I just found this thread. They won't sell the hinges. I've gone 7 rounds with them. Their solution is to buy a new cover. I'm about to buy a new cover and it won't be a Bakflip. It also won't be from realtruck.com.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.
