I wouldn't sweat it every vehicle has to break in and when you have metal on metal at those speeds and temperatures any imperfections are coming of I think they call it casting shavings or something shards that long could only come from your thrust bearing if something was malfunctioning anywhere else i.e. Bearings lifters valves everything else would be way smaller or shorter than that if anything was malfunctioning I'm super anal ocd adhd and that shit would drive me crazy till I had à one I trusted or at least a couple dozen people from the Internet tell me the same thing about it and then it would still be in the back of my mind looking at the pics I'd say she is breaking in just fine.

 

I have an 04 Tahoe 5.3 160k z71 murderers row black lol just kidding I just made that color up and named it after the 1927 new your Yankees line up haha anyway I've got the no oil pressure thing going on and when I pulled the pan to change the oring on the pickup tube discovered an enormous amount of very alarming size metal shards big ones like I've never seen metal like was in my engine in any other engine that was still running I immediately thought bearings but after inspections and replacement for no other reason than to waste money and discussion on here with Doug Scott and dirt they helped me come to the conclusion that all the ginormous shards in mine were casting shavings from break in evidence to help support this theory I had changes oil several times since I bought the vehicle 4 years ago before I pulled the pan I flushed the engine with seafoam in the crankcase ran it drained the oil and this was the first time I'd ever seen metal on my drain plug pulled the pan and really got worried but in the end granted I still don't have any oil pressure but I changed main and rod bearings oil pump pickup tube oring timing set all gaskets and seals anything that has to do with oil pressure it has a new part on it still no oil pressure but the point is that mine is 04 and still had to mongo shards in it why had I not seen it on the drain plug before just speculation but I'd imagine it was from running the sea foam and it broke the sludge in the pan up a little and that's how I'd never seen them before none the less from visual ll

Looks normal to me. Read in the owners manual about the 2 stage oil pump.

 

The 4.3L (L83), 5.3L (L86), 6.2L (LV3) engines are equipped with a two stage oil pump.

The oil pressure gauge jumping three times is caused by a test routine the engine goes through during the first few minutes of driving to insure that both stages are operable.

The oil pressure gauge going to 60 lb. over 3700 RPM, is the calibrated engine speed the oil pump goes into the high pressure stage.

This is normal operation for these engines.

Yes I have the oil and the filter "from my truck " it is still producing oil shavings and slivers and today I noticed my oil gauge holds 20psi at idle 40 from 2-3k rpm and when I hit about 3700rpm it doesn't just increase but more of a straight up jump to 60psi not a smooth type increase seems almost like a sticky gauge problem but with shavings wondering if oil pump is having some problems I have a video I will try to get on here

Too much pressure is better than not enough. I don't think the engine will blow from the oil being pumped too fast or too much other than the pump itself going out and you continue to let the engine run without oil pressure.That's how the 2 stage pump works in your video so it will last since it's working as it's designed. If a regular pump is pumping faster than it's designed then it can wear out faster than normal but that won't hurt the engine unless you let it run after the pump goes out. As long as it doesn't stay around 20-25 psi all the time you're fine.

Hi, 

 

any news on this?  Two months ago I purchased a 2017 Suburban certified pre-own with only 17,000 miles and I have the same problem.  Now my truck has 19,000 miles.  

 

I am going to the dealer tomorrow.

I have the same issues with my truck, and I am going to try to sue GM for it.  I had 20,000 miles on my truck with multiple oil changes, and I still found metal particles on my dipstick every time I checked the oil.  The engine got so bad the crankshaft started squeaking against the front main bearing!  The dealership replaced my crankshaft, bearings, piston rings (for some odd reason) but I am still getting metal particles 3,000 miles laster.  I took it in again and they told me that it is having issues but I have to wait for a failure.  The idle is rough, there is a lack of power, and it is shedding oil like my dog sheds fur.

      DTC P2C48 auxiliary cooling pump

      I tried tapping it.  This might sound like a dumb question, you should feel vibration or some type of noise when it turns on? Can someone please verify? Thank you all!

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      I feel better now for my own view point and actions or lack there of towards the dealership service theme reading your post and others. GM corporate is who offers the two free oil changes on the HD trucks and I bought my truck in Feb of 2025 and those oil change offers run out within 2 years I believe and I highly doubt I will be using either one of them. I had asked if I could officially give those free services to another customer ( a friend ) and they said no, its all a GM corporate thing based on the vehicle in question. What that service advisor did however was go into a little story about how such and such customer was denied engine warranty because he had done his own oil changes because then they are not documented ... you see where that goes and so an employee playing the game of scaring the customer into having the service work done there most certainly triggered my thought process. At a later date I did talk to the person who handles warranty claims at the dealership and she said to be sure to document the oil changes and keep receipts for the oil and filter ( coped the receipts from cases of Mobil oil and case of filters I bought from them ) and the vehicles VIN, the date of service, mileage etc and staple that together as a record I would give them if that was ever needed and I keep my own log book for services for each vehicle as well. Oh and about 8 months after I bought the truck the dealer starts calling me to offer a maintenance service since they haven't seen my vehicle show up on their system ... for the mere fee of 300.00 Canadian to change the oil and rotate the tires and a few other minor checks and I declined the offer, I get the call again a couple of months later for the same thing and she could tell I was not interested and she asked if they should take my name off the call list and I said yes, do that !.    By the way did you happen to keep your factory oil filter to open it up and see the surprises inside as I expect some will show up as per the odd little sliver of metal shaving and particles that the filter does trap along with bits of grey silicone sealer that come off of the inside edge of mating surfaces. I have cut open every filter so far on my truck although few miles but have changed the oil often and the second filter was vastly better with very little of anything, that first filter was the unsettling one as I expected it would be.

      OCI, not when but why?

      I get why they do this…but man…not ideal. I only extract on inboard boat engines because the drains are buried and even then I hate it because it’s easy to leave a quart behind with that method.   They should market it as an “oil refresh” not oil change!

      I only get oil changed where I can watch. Valvoline pulls through the dipstick into a see thru glass. When done they show me the dipstick. About the only way they can mess up is using the wrong oil. But that secret wouldn’t stay secret long. Honda uses TQ wrenches on everything. You can watch through a plate glass window. Discount tires does that with tires. Trust but verify.

      I would not argue that with you. It would be pointless to argue against the truth and you speak the truth.    My question and in fact the entire point of this thread is an exploration into the levers of wear which happens no matter how well we maintain our powertrains.    Some of these levers we exert a good deal of influence over which can and do result is lower wear, longer powertrain life. Some others we are sort of stuck with.    An engine is typically done when the ring to bore seal no longer is able to do the job effectively. Normally the first thing to go in a engine otherwise well maintained and adult driven is this seal.    Looking into the means, methods, products and attitudes that influence the rate of wear seems a worthwhile inquiry to me.
