Guess I should have traded it as soon as it was fixed. I pulled out of a store parking lot and started accelerating when she popped. Now it's down at least one cylinder and the engine light blinks any time you try to accelerate. Kinda has a "squeak" to it. No codes, at least none my code reader could find.

 

I know exactly what's going on because I remember in vivid detail the last time it happened back in 2020.

 

Between this and the box being rusted out after only 7 years, I think I'm done with this truck. Worst. Time. Ever. To be truck shopping...

 

141K miles. Box rusted. Engine blown. Is it even worth fixing? What's it worth as it sits? Not much I'm sure...

If its just another bad lifter, the engine isn't really "blown".  That can be replaced.

 

You have to look at it from a resale point of view, if you are trying to unload the truck.  Its worth much more with a fixed engine than it is the way it is, rust aside.  

 

I'd toss a couple lifters in it, so long as the cam isn't bad, then if you want it gone, sell it.  

 

Also, greetings from the other side of the Genesee (Webster/Penfield area).

All around the wheel wells. 

 

I even bought the membership at the local car wash and ran it through at least once a week year around.

Last time it was nip and tuck whether it was fixable. Any little thing didn't go perfect and it went from a $2500 repair to a $10000 repair. Fortunately the head wasn't damaged. Fortunately the cam wasn't wiped out. Fortunately a valve didn't hit a piston. Fortunately the pushrod broke off clean and fell to the bottom of the crankcase without hitting anything.

 

I also got a little break from the dealer because the truck was barely out of powertrain warranty the last time it happened. They went out of their way to fix it rather than just ordering all new parts. At best GM would have split the cost of parts with me, and I was still on the hook for the labor. GM would have insisted that everything be replaced, and that would have been $6000 instead of $2500. That won't happen again.

I have never seen vehicles so badly rusted as in your area, the salt they use seems extra corrosive

This one is a record for me in modern times... My 2003 was 12 years old and was JUST starting to show rust around the wheel wells. Quality has sure gone downhill if this is typical.

 

By the way, I just talked to a guy in my model airplane club who is a GM-trained mechanic that runs his own shop now. Completely forgot that's what he did for a living! He's going to take a look at it and see if its worth fixing.

 

Anybody know a good set of fender flares?

Quick tip, go to https://www.chevytrucklegends.com and join. Then they have a 20% off on OEM accessories. Then when checking out, the key is to choose to have the item shipped to your local dealer and shipping is free. That saves even more on larger items.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Active Grille Delete

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?

      Tire pressure for 37s

      By PBNB · Posted

      Do you think this width might affect the chalk test with a higher pressure closer to 65psi? I think lowering the pressure makes sense to get the tread to lay flatter
