Another engine failure

[FULLTHROTTLERICK]

Quick question, was this the MOPAR MAXCARE Factory Extended Warranty? ....Found the exclusion... Ok, what is the best way to prevent Injectors from clogging here then? I use only Costco 93 Octane top tier fuel. I have every fill up receipt since day 1.

edit:
Exclusion:
GASOLINE ENGINE: Cylinder Block and all Internal Parts; Cylinder Head Assemblies; Timing Case, Timing Chain, Timing Belt, Gears and Sprockets; Variable Valve Timing Solenoids and Actuators; Harmonic Balancer; Oil Pump, Water Pump and Housing; Intake and Exhaust Manifolds; Flywheel with Starter Ring Gear; Core Plugs; Valve Covers; Oil Pan; Oil Filter Adapter Housing; Turbocharger Housing and Internal Parts; Turbocharger Wastegate Actuator; Supercharger; Fuel Injectors (excluding clogged injectors); Serpentine Belt Tensioner; Seals and Gaskets.

I believe I have the 8/85 on both my vehicles...(No way either will be at even 40K miles) in 8 years though.

Is Costco top tier fuel an oxymoron? I can’t imagine its nearly as good as shell/BP/Mobil but im no expert.

Costco really is top tier, not a member so I've never used it myself. We try to always use Quiktrip and save receipts; surprisingly it's also top tier and they guarantee their fuel.

Hi there, to provide some clarity, goodwill is handled at the dealership level. The Dealership will submit a goodwill request on behalf of the customer. The Dealership will inform the customer directly if the request is approved or denied once the request process is complete. Any offer from the Dealer to the customer is final and cannot be disputed.

I know who submits the paperwork had it done plenty of times, but if it can't be disputed or changed why would the customer get different numbers of coverage? Maybe should look into that not explaining the process.

Costco and a bunch of stations in our area just filled up diesel in regular gas… so there is that top tier goodness fresh in my memory.

Something else I noticed which had to do with the mixup. “Top tier” appears to be slightly ambiguous.
The supplier which had the trucks delivered to numerous stations across the area and when they tracked the trucks route it went to several stations which have the top tier advertisements and then a few that don’t.

Take that for what it’s worth, but it appears some stations pay for an advertisement and get top tier while others do not and still get it.

Yep you gotta buy into that top tier advertisement stuff but from what i hear it usually means solid gas. I'm not sure if BP is still in that top tier class but i know their gas is still pretty solid. It's tempting to use bargain gas especially when prices are this high but we fill up with good gas virtually every time. Only exception is on roadtrips when we're almost empty and it's a matter of crap gas or no gas lolol

Just your basic maintenance... the occasional fuel injector cleaner (I've always liked Chevron Techron). On the off chance that an injector does clog, and on the off-off-chance that it doesn't free up with a good cleaning, a new injector is $65, and takes all of 15 minutes to install - no big deal. And like I said before, a clogged injector doesn't do any engine damage - that cylinder just doesn't get any fuel, and you get a misfire. It's only when an injector sticks open and leaks fuel into the cylinder while you're parked overnight, filling the combustion chamber with enough liquid fuel to hydro lock the engine, that engine damage occurs.

In the OP's case, I have no doubt the dealership is the one who damaged the engine when they tried getting it to start. Even at wide-open, 100% duty cycle, an injector can't flow enough fuel to hydro lock a cylinder when the engine's running... it just sprays raw fuel throughout the various cycles, dumping that fuel through the exhaust, and creating quite a smoke show, as the OP found. It's not good for the cats, but that's a different issue. When the OP shut the truck down, the pressure in the fuel rail bled down through the stuck injector, dumping the contents of the fuel rail into the cylinder.

All the tech had to do, before starting it, was pull the codes. He'd see the misfire code(s), and say to himself, "self - these misfires, combined with the owner's statement of rough idle and smoke, could point to a stuck fuel injector. Let me pull the plug on the misfiring cylinder, and have a quick peek." But that requires a level of thought and experience sorely lacking in most parts changers these days.

I know - coulda shoulda woulda, hindsight 20/20 and all that... but I just have this image in my mind of a couple of parts monkeys flogging and abusing the truck without much of a clue as to what they were doing, until the damage was well and truly done - then just staring at each other and grunting cluelessly, like when the cave men discovered the discarded Coke bottle in "The Gods Must Be Crazy".

I would love to know why the split changed. I didn’t really get a good explanation. Do have a whole text history of what has happened up to this point.

Great thread on BITOG on this topic: https://bobistheoilguy.com/forums/threads/fuel-tanker-driver-here.312705/ There is a lot of opportunity for error which is why I always save my receipts. LOL

Everyone is talking about a clogged injector. How does a cylinder hydrolock from an injector clogging? It would be the other way around where the injector stayed open, filling the cylinder with fuel, then trying to compress.

So my argument to the warranty company is that there was never a clogged injector. The injector had to have stayed open.

It wasn’t clogged, his was stuck open. The clogged part showed up because that is not covered.

So if clogged isn't covered, is stuck open covered? Injectors are not a maintenance item.
