Yup, the confidence is kinda gone. Theres a chance it can be restored with a proper diagnosis, but those are hard to come by since the dealer just wants to kick jobs out and make them go away without properly diagnosing. I may just get rid of this one and replace it with another truck. Still stuck in bishop till tmrw morn, then hopefully will get some answers from the dealer. Not confident in the dealer either, plus that $175 labor rate doesnt help.

Impressed with initial interaction with GM senior service rep. In talks to have my tow covered, repair covered, future protection against recurrence, and beginning talks of buyback. Too early to tell if and what theyll do, but 🤞

Just got back from bishop, my truck did not. AAA is a total joke, I was filled with misinformation from them like a pornstars bunghole. Accentuated by a storm that rolled in last night and all tow companies being backed up and too busy. Limped it to the towyard, where it sits now with my camper on it, until they can get a driver to tow it all the way down here to cat city.

Purchased the rv service upgrade, told i get 200 mi of tow free, i was braced to pay the addtl 108 mi, but this morning, as i sat in wait for my tow, in the gale force winds and snow, they pulled the rug, hard. Changed their tune and said only $1k would be covered on a tow that is near $3k....supervisor didnt help. I was calm and cool and understanding and just got noped, hard.

Stay tuned for more looney tunes folks!

These days, my anus is in an always-prepared state.
Everything else in my life is going great, starting a good new job on 6/7, moved in with my lady, been playing out in the mountains, etc, etc. Boggles the mind, like what did i do to who andwhen? Prepaid karma? Like a burner but for karma?
At least it let me play in the mountains and return home safely before reopening my anoos. Perhaps an incredibly strong omen to let my old job go? I dunno, but im exploring options and scenarios and staying in good but not overbearing contact with my senior service rep CA engagement team.

Scenario 1:
Have Gm cover the tow from Bishop to Cathedral City, cover the repair (since it was just in the dealer for the same issue and everything checked out “fine”)
Then have them issue a guarantee against recurrence for xxx miles, since this happened again after 650 miles
Carmax the truck, get another (as nothing else suits my needs like this one does), cross fingers

2:
Explore buyback option, get another truck, cross fingers again

3:
Trade in after scenario 1, get new colo twin truck, cross fingers

4:
Jump ship, get some sort of gasser, Colo twin, Tacoma, Ranger. Cross fingers again.
Potentially, even one of the big 3’s half ton diesel options, but i really dont want that, i dont want a full sizer

Anybody got any other ideas?

"These days, my anus is in an always-prepared state."

I'm F-ing dyeing over here LMFAO..... too funny.


I know exactly what you mean it's a crap shoot no matter what manufacturer or where you go and buy. If you get the Monday/Friday built vehicle then it is what it is, one can only can hope for the Tuesday -Thursday built vehicle. The twins are perfect for me as well, fits in the garage and can still move around it. Carries what I need it to carry and tows well.

I keep saying to my better half if this thing starts being a POS then I guess I will go for a 3.0 FS truck. I really don't want to go that route, I really like this truck plus all the stuff I added on really would get tossed down the crapper. The 36 gallon fuel tank just kick ass especially when towing, it doesn't suck with 1000+ mile range when not towing either.

Personally I think the dealers don't give the techs enough training or time to figure out complex situations. It's just throw parts at it as fast as you can and hope for the best resolution. That's all fine and dandy until there is a multi faceted breakdown going on and any one part doesn't resolve the situation.

Congrats on the new job, maybe that will take you mind of wanting to drive it off a cliff for a while.

Any cliffs in my future would have to be dealt with as a pedestrian....certainly nothing is that bad.
I certainly couldnt agree more with the quality inconsistency, its staggering.
Also couldnt agree more that there is not enough training of the techs in these “lesser” duramax. Ive certainly heard that verbatim from independent shops, and seen evidence of it in 90% of my dealer experiences. To the point that they have voiced that they are unsure even how different the systems are between the large dmax and the baby ones. Thats one of the main points im discussing with the Gm service rep, lack of effective and proper diagnosis due to lack of training, knowledge, or resources.

Im now wondering how trained and knowledgeable the techs are in the 3.0 duramax six, is it a similar story to the 2.8 four? Could be, time will tell, they certainly aren't prevalent like the full big duramax are, but they certainly have quite the price tag themselves. Doesnt make sense how they introduce a product to the lineup, especially one that sells like the 2.8, which is pretty well from what ive seen, and offer no tech support or training. Hopefully not the case with the 3.0.

also wondering if this is a similar case with fords half ton diesel and fca ecodiesel.

I just came across this video from the Colorado fans site. Interesting that no bottom end parts from FCA are available for a rebuild. It's getting to the point they are really trying (and succeeding) on getting people to just dig themselves in debt deeper rather then helping. I think that the lack of training goes right along with this thought process.

As far as the 3.0 goes and proactive tech training, I guess that will depend on how many units they sell for the bean counters to determine it's in GM's best interests or not.

GM was a no show on their promised monday check in call, of course. Ive sent an email and left a voicemail. We’ll see....
Cant say im surprised, but hoping for some sort of response. Truck is still sitting in bishop untill apparently thursday, their projected day for my long distance tow.

Wow I can’t believe you were watching this stuff at the same time I was.
The first gen eco diesel, if you remember they had rods bearing issues so Ram said everyone stop using low saps oil.
Rams new recommendation was Rotella 5-40 synthetic....
But that didn’t cure the issue.
When these engines were torn down people found all the lower end bearings torn apart.
One of the vids I was watching last night had all the oil ports clogged with what looked like hard soot.
The crank main bearings were half out of the caps. All the rod end bearings were destroyed.
Then I watch another video that the guy says oh oh it’s making a metallic noise. He says watch guys this engine is about to blow up. And 30 secs later it seized solid.
Then another video shows this guy talking about all the issues like crank shafts breaking in half.

I started feeling real good about my truck after watching these eco diesel vids.

One guy says the recall that Ram did that was supposed to correct there pollution control system. Where the EPA caught them making to much pollution. After the update everyone was complaining about the truck being gutless and major dead pedal after the computer flash ............there was actually a retune for the transmission so it would down shift earlier to prevent any possibility of lugging.
Aperantly Ram thought the low rpm was damaging the crank shaft.
Lugging an engine is not good for it ....I do agree with that one.
All you guys trying to get your truck in 6th while towing take not....... not a good idea.....

From hat I seen it does look like soot plugging up oil passages may be one of the issues destroying these engines.
Ram uses 10 quarts and says something like change every 12,000 miles.
I truly believe the amount of soot is extreamly damaging.
Oil needs to be changed more often than they say.
Dont follow that dumb as dic ........ it’s useless ... The one on the instrument cluster. Not the one between your legs......lololololololol

In that video he mentions a carbon build up that is blocking the oil flow.
That is 2 videos that I have seen that shows the oil ports blocked with what looks like carbon..
Its soot. As the soot impedes the flow of oil the bearing gets real hot and the soot turns to a solid....
To me it looks like heavy amounts of soot in the oil collects at the bearings. Tight tolerance means this soot can’t get out. So it collects and eventually blocks the flow of oil.

What if this is why some of the 2.8s wrist pins are failing!!!
Lack of lubricant due to heavy soot buildup!!
Makes sense...to me

One of the other videos I watched was about a guy that thinks it could be soot issue also and he has been changing his oil more often.
He has high mileage and no issues....

What is a good soot %? My Blackstone's every oil change %s are <.5%, and I change my oil every 6,000 mi or so with Castrol Euro Dexos2 5w30.

Also at 39,000 mi, the Provent has removed 23 oz of condensed oil vapor since it was installed at 7,000 mi.

i truly believe those oil sampling reports are a wast of time.
I bet you could send in pure soot and it would come back soot level ok...

I been watching all those reports for years and they all come back ok.
That has to tell you something.... never seen a bad one.

personaly I think you need to change the oil between 3 - 4 thousand miles.
I have read about so much damage from these oil change monitors it makes me sick.
The only reason there there is so the MFG can claim low cost of ownership.

So here is what I think is happening
Now that MFGs want to use thin oil for better mileage. They have to run tighter tolerances.
If they didn’t tighten up the tolerances the thin oil would run right past the bearings and back into the oil pan.
With out tight tolerance a thin oil wouldn't build any or at leas much oil pressure.
Oil pressure is the oil pump pushing oil through small oil passages. The thicker the oil the harder it is to push that oil out the oil passages.
Now change to thin oil.... and the oil finds its way out around main journals and rod end bearing to easy.
The fix is to run thin oil with tigh tolerances. This will allow the oil pump to build pressure.

The killer is if those tight tolerances keep the soot from getting out of the bearing journal’s with the oil bad things are going to happen.

Ok I’m typing to much here. You guys will be tiered of me......
But
Why do you need oil pressure and why is the correct oil viscosity so important?

The oil pump will only pump so much oil. At idle we need enough pressure to float the bearings so there is no metal to metal contact. So oil is pumped to areas like rod end bearings and crank shaft bearings. Oil leaks out around these bearings and back into the oil pan.
we need enough tight tolerance so the oil doesn’t leak out around the bearing to easy.
The oil pump will work its asss off pushing oil and since its hard to get out around the bearings it has to find some other place to go.
And that will be up to the cam shafts and the piston cooling jets ect ect.
Its a critical balancing act. To loose a tolerance at the crank and rod ends and there is not enough pressure left to get the oil up to the cams. As it all leaks out around the bottom end bearings.
To tight and the soot doesn’t get out. It just stays in around the bearings until it blocks off the oil.
Same as running a to thick an oil.
Thick oil will be very difficult for the piston cooling jets to squirt the oil up to the under side of the pistons. Those jets are made for thin oil. Thick oil will not flow properly through them.

On the Eco diesel you will notice the cam shaft bearings all seem good.
But the crank and rod end bearings are all destroyed so oil was still being pumped to areas that were not blocked with soot.

Back in the day when all diesels used 15-40 oil the tolerances were not that tight. Diesels were noisy and clattering very loud. Large amounts of soot had little effect.
So is this what today’s oil analysts are comparing it to. (The old days of diesel)
?????
Its a whole new engine design today with very thin oils.

Well, opinions not based on facts are not worth much. As the CFO of a major Intermountain west flatbed/reefer hauler running 1,500+ power units, I can tell you our service techs and Cummins SWEAR by Blackstone and oil analysis!

Their judgement is good enough for me. My previous post query was to get some input from other forum participants about this issue, and you've posted yours.

Thx
