Well, thinking out of the box. What is the cause.of the mains going out? Trash, cheap bearings, machining, too light of oil?

 

If'n I had the 6 2 tick tick boom engine, I might entertain putting rods and mains in it right away. Be down a week or less and not stranded on the side of the road for a month or more.

 

Used to roll bearings in the frame on OTR trucks for a living just as a mileage precaution. Can't fathom bearing trouble before 50k.

Good question.  These seem to be the trucks that were put out during the pandemic.  So did the supply chain get messed up with lesser quality parts? Odd that they are having issues like this at low mileage.

Well, this one is a first for me.  First engine failure on a low mileage/warrantied daily.  Have blown up lots of hot rods and toys, nothing stock at 15k though.     Was on my way home from

Just wanted to post some updates.     Got the truck back first week of December.  Dealer rebuilt the engine.  Truck seems to run good, except for anything Onstar related.  The module apparen

I recommend you go over to the ram forums and read up on the 5.7 as they are having their fair share of engine issues from lifters to cams, manifolds etc. It's not just GM.

Wonder why the 5.3`s don`t have the same number of bottom end problems? Same bottom end except piston. Same crappy parts.

 

Could it be the higher hp mixed with 0w20 oil, and truck duty = a bad recipe?🤔

Oil weight has nothing to do with it. I can make a 5.3 have the same power if not more with a supercharger kit and nothing else, still running the same oil and it won't have a failure because of 0W20.

That's quite a claim. 

 

So, GM track day recommendations are in error? 🤔

I`m almost 61 yrs old. Started mechanics for a living in 1985. Looking at the track prep above got me thinking. The more things change, the more they stay the same.

 

1`st oil change at 500 miles, take it easy for the 1`st 1500 miles, etc. Sounds exactly like the advise in the old days. Even with these modern engines.😉

 

Wonder why GM, and all the other manufacturers don`t put this in the every day man`s owners manual?🤫

I have a Pontiac 455 [463] now. It has around 630 hp/600 trq. This thing goes to 6400 rpm`s with 3.25 main bearing journal, 2.25 rod and a 4.21 stroke. I started out new with 30w. Used 10w30 for the next oil change and has 20w50 in it now. Runs like a clock.

 

If oil weight has no effect, I wonder what would happen to this thing if I ran it to 6400 rpm`s with 0w20 oil? Especially in the Louisiana heat?  Betcha this thing has bearing problems.  Just sayin.

 

Unless there is a block problem or so, why does the 6.2 have bearing problems and the 5.3, not so much? I know these engines are not the Pontiac 455 but the 5.3 and 6.2 are the same except for the hp.

 

Just thinking out loud on the computer.🙂

I read somewhere recently the blocks have an issue. Maybe @newdude has the 411 on this :dunno:

Like Bugs Bunny used to say;

 

Hmmm, well, could be.🙂

 

Only other difference is the cast crank for the 5.3 vs the forged for the 6.2. Maybe a journal finish problem?

Seems GM should know how to finish a crank by now? The bearings are the same.

 

They should have guys in white robes to figure this out?🤔

There's been a few reports I've read.  Machining debris, oversized lifter bores and misaligned main bores.

I don’t know anything about the assembly process. Most everything is machined in mass by automation. That would mean more than a few out there are problematic. Otherwise these would have been discovered and not sold. Seems logical to me.

Since when is a 5.3 and 6.2 truck engine the same as a LT1 in a camaro that goes racing?

 

If I was taking my truck to a race track and constantly beating on the engine like it owed me money, I'd probably switch oils too....

When you put a blower on it. That was the claim, right? 😉 Pressurize and pulverize? 

 

Two things a motor doesn't know Camron. What it's in and what name is on the valve cover. A 5.3 towing is getting worked just as hard as a track car. Harder perhaps.

Since when can GM not build a small block V8?

 

1. Failing lifters

2. Lifter bores

3. Misaligned main bores

 

All within the last 4 years.

 

If there was 1 thing in the history of GM that they could do right it was a small block V8.

Keep cutting corners and soon there is nothing left.  :(

Since pandemic/getting paid to stay home/quality control took a dump/lowest bidder/even the suppliers are getting from the lowest bidder.

      2019+ Brake failure, it's complicated

      By needafix · Posted

      I'm not sure if this should be a new topic, let me know if it's out of place. This my first post. Thanks 85077522 - AC Delco GM Genuine Parts Brake Master Cylinders. Anyone else had to replace this brake master cylinder yet. I didn't do any brake work, it looks like new parts and I've had the truck for about 4k miles, 119k total miles.  When it started to throw codes I did the calibrations with a bidirectional scanner and got the codes to clear but they came back so I did the routine; base bleed, automated bleed and final base bleed. All that with Bosch ES16-32N fluid (please look it up). That seemed to fix it but 100ish miles later it failed again so I ran the same process but with a pressure bleeder this time and got the same results, fixed for 100ish miles. The original fluid looked bad and I thought I got most of it out, it could've been the wrong fluid. The codes; P25A2, C05B0-00, C2A1B. I can get them to clear but not for long. The C05B0 indicates a leak in the front circuit (which is bone dry) so I'm thinking of doing the bleed process on that front again today and I don't know if that's taboo to just do the front but at this point it seems like it's worth the try anyway. The new master cylinder/module unit is supposed to get here today. But now I'm pretty much convinced this install is over my head. I've called several shops and some mobile guys that I know but this thing is like radio active material, scary wise. I did get 2 local shops say they should be able to do it, one says he has the SPS2 programing capability. And with the battery disconnected is there supposed to be pedal resistance, mine is to the floor, then if I pump it I can get some resistance. I had a panic stop prior to this issue which may have contributed from what I read. And on the first attempt to bleed and hydraulic test the scanner listed things to look for and one was any gaps between the pad and rotors which I did notice on the RF corner and I removed the outer pad (where the gap was) cleaned it and the hardware and didn't see a gap after that but will re-check it. I read that if pushing the caliper pistons back then you're supposed to open the bleeder so as to not push fluid backwards into the abs module or it will damage it. If that's true then that's also a possibility from the previous owner having the brakes changed before I got it. I'm using an XTool ip500 scanner. Any suggestions, questions and comments welcome.

      Next Friday will be my 6 week point from my right knee replacement.  The surgeon says it will be fine if I choose to drive after this checkup.  I know I could drive now but best to do as my surgeon (and my wife) tell me.  Richard compared being 62 to 72.  I remember when I was in my early 60's I was experiencing slow but regular decline in my mobility.  Thanks to good medical support,  i continued to fight the speed and spread of this decline. During my 60's I worked on non-surgical methods and just when I turned 70, my orthopedic surgeon recommended joint replacements.  In a little over a year, I had one shoulder and both knees replaced.  This hasn't been a terribly fun experience, but worth the discomfort as my future mobility health trajectory has reversed.  It is a treat to now be watching my mobility. balance and confidence steadily improve!
