Metallurgical test on the pushrod? if found to have a weak spot you may be back in business. Bad metallurgy trumps tune every day of the week IMO. But it's GM so who knows.

 

Have you every used this before.

Update:

 

The Dealership has replaced the pushrod and the engine is running fine. We are still discussing everything with GM so no final word on the Warranty Issue yet.

 

Im still trying to figure out why this push rob is broken. The Lead Mechanic at the dealer ship is puzzled that nothing else is wrong with the engine. They have never seen this before on a 6.2L.

Almost. Had The same thing happen with a set of Elgins for my GP. Was going to have it tested but Elgin sent me a new set to hush me lol

FYI, I don't think removing the tune before you brought it in would matter. The ECU counts changes and would flag that something had been changed. If GM didn't make the change (they keep a count/log of each vehicle's changes), they know that you had a tune and removed it.

 

Sorry about your problem. I'm skeptical about their claim that only the rod failed. Either it was a bad rod, or something caused it to fail.

Was it still one piece, or did chunks break off the cracked pushrod? If chunks broke off you might want to pull the oil pan and get the debris out. (No idea if that's feasible on these trucks.)

 

I'd start doing oil analysis too.

I don't see how a tune could make one pushrod fail either. The only way I can see a pushrod issue is if you revved it above it's limit but that would cause more than just one pushrod to fail. I'd push hard for GM to pay for this.

      Injector update

      By iso221 · Posted

      Because single shot injectors are ancient and multi hole injectors provide smoother running engines and sharper throttle response due to the fuel being atomized better..the best lead I have is a 24lb blue top injector almost everything matches up but the injector will put out about 26lb/hr which is just outside the gm threshold.figured id ask here to see if there was an absolute answer

      Why is my question?   Any change in injectors requires a tune. Unless you are going back with the OEM part number or a newer part number of that same injector.   Any size difference or type difference like the EV6 style injectors all have different injector data for them. And there is no EV6 injector that matches the factory 25 lb/hr size that your truck comes with. I've been messing with these trucks and tuning them for a long time and what you trying to do doesn't exactly make sense to me.

      When a condition becomes a business model.    https://www.gm-trucks.com/gm-truck-suv-incentives-pricing-2026/   Zane posted this in "Latest Articles".    The honest bottom line   Truck buyers have spent three years assuming this is a temporary condition that will break once inventories normalize. GM just presented it to investors as a durable strategy, on a chart, as evidence of good management.   Inventory did normalize. GM is at 511,000 units and squarely inside its own 50 to 60 day target. The discounts still did not come back, because the low incentive number is the goal rather than a symptom of shortage.   Plan your purchase around that reality instead of waiting for it to change. Follow our ongoing GM News coverage for pricing and incentive changes as the next-generation trucks land.

      Thought it was raining this morning when we woke. Nope. Dew point was over 80 F and humidity 98%. Zero visibility distance. Everything was 'sweating'. I've seen rain come out of clouds but never out of Pepper or the tree trunks.    Wicked storms just missed us sliding off to the east but by blocks. Heat index about 110 F with air temp in the 90's.    This is  our third wave this month of multiple days of this type of weather. And yet the grass is going dormant and the ground is cracking this side of the street and water up the the hood opposite. Just weird stuff going on.
