Same garbage lifters. 

 

I traded in a 22 L87 that had the lifters done twice 7800/33k for a 25 and before the new car smell wore off, the engine's knocking. 

 

Dealer already acknowledged, and told me to get in in for repair. 

 

Guess I expected this to be resolved on the 6th year of the DFM L84's... Guess not.

Bingo.  As does the LT1, LT2 and LT4 in the Camaro and Corvette and those use 0W-40.     Goes to show you that the 0W-20 move was all about fuel economy goals to meet CAFE and CARB.

When my 2020 Silverado 5.3 hit about 120k miles, I pulled the heads and swapped lifters and pushrods "just to be safe" since I needed the truck to go 200K miles.  At that time, I also switched from 0W

I would keep my mouth shut at the dealer but, I have been running that oil in mine since 600 miles. No problems. Engine is more quiet than 0w20. Got 7800 miles now. If that oil was too thick, I would

Same lifter covers all the way back to 2007 so........................................

 

There's a TSB for that noise actually too.  There's a TSB about that type of tick like that.  Assuming there's no bent pushrod or collapsed lifter, its just a lifter that's not hydraulically pumping up like it should.  19-NA-218 1..3

Newdude is correct on those lifters. They go back a long while. My brother has a 2007 Avalanche with the 5.3. It has 173,000` ish miles. A coworker of mine has a 2010 Tahoe with the same engine. It has 200,000 `ish miles. Both have never been opened up and run like swiss watches. The Avalanche did have a solid tick for a day or so, in the past. I heard it. It went away on it`s own. That was a few years ago.

 

Thing is, these things were not spec`d with a certain oil.🤔

 

I will say though, I would be pissed if my new truck sounded like that. I do have a `25, L84 with 7800 miles. It has had, since 600 miles, 5w30 in it. Sooo...

I have an 02 Avalanche with 190K miles on it. I bought it with detailed written maintenance. The transmission and rear end got their first fluid changes at 167K. The oil got changed with regular oil every 3K, the filter every 6K miles. I’m letting my grandson drive it. I’m sure he’s not gentle on it. My brother in law visited this weekend. He drove his 06 Tahoe with 250K miles on it. All original.

So would I have an issue running say 5w-30 oil?

So what exactly is making the knocking noise? The cover, pushrod, or the cam striking the lifter as it comes around becauseits not expanding fully?. 

 

My dealer replaced all 16 of the lifters, and 2 pushrods on my 22 L87. 

 

This morning the noise wasn't as pronounced but it was like 90° already when we started it. It doesn't do this if the engine is warm at all either. It was more of a light tap.

It appears that TSB only goes to MY 22. Does it apply to newer vehicles?

Keep us up to date on your choice of oil. Is it Mobile 1 Dexos? I would run 5w30 in a heartbeat if it didn't void my warranty.

(I got a Lifetime Powertrain Warranty from my Dealer). I have to do my servicing-oil changes with them unless I'm traveling. I don't rack up many miles because i ride my Harley every day when its not snowing. The Warranty was free with the purchase of the truck (believe it or not) Being a Mechanic (retired after 40 years) I think you are absolutely right running the thicker oil. Best of luck man.

I’m running a thin 5w30. Valvoline Advanced. Dexos 1 gen 3 rating.

Wow you let a 4l60e go 167,000 miles before changing out it's original oil? You need to go buy a Powerball ticket because no chance in hell should that thing still be working imo. 🤣 Most dont make 100k before needing a rebuild, and that is on a well maintained transmission too.

I bought it with 167K miles. But it wasn’t uncommon because the owner manual stated 150K fluid changes and antifreeze changes. I had several in that time period that had the same service schedule. The first truck I had with 100K tune up, spooked me. I asked my mechanic I used after the warranties were over about it. This was on a 2004 Z-71. At 100K miles I asked about the plugs. He said wait for the check engine light. I was in the process of giving it to my son. At 150K miles with did the transmission, brake fluid, front brakes, transfer case and rear fluids. He traded it in at 185K. Same plugs and rear brakes. The good old days. The was at least 5 trucks in that period. Not going to work today.

I used to be a mechanic at the dealer I bought from. Wonder if they would go soft on me?🤔

Probably. I doubt like hell any dealership is going to be doing oil analysis. You know they're losing money on most any warranty repair.

      Oil Consumption

      By Chuck FB · Posted

      So speaking of oil consumption with my L8T as I just changed the oil yesterday and made the switch over to Amsoil SS 0W-40 from the Mobil 1  5W-30 Truck and SUV I just dropped out. 2900 miles on that oil as well as  68 hours on that oil ( so used to equipment with an hour meter and that becomes valuable information to compare with others as well ). Once again the oil use was so very little, I am going to say it dropped under 1/16 of an inch on the dipstick. No towing was done and this interval was from early spring until now.    One interesting item to note is that going by the 5 quart jugs I was using before from Mobil, it was showing that I was putting in 8 US quarts to bring it to full if not slightly over the full mark according to their jug markings. Granted I did allow more drain time this time and in part because the engine oil was only lukewarm as I started it and let it idle and not for long enough to get the oil itself hot ( the engine was up to operating temp ). The oil in that state just seemed to take forever for it to drip out but not only at the drain plug but at the oil filter housing as well, perhaps I had never quite gotten all the oil out before and I could have still waited longer but as it was I waited well over 3 hours. I think next time if I have the time I will do an experiment by dropping the oil and lets say leave the pan under it for 15 minutes, then switch to another pail and let it drip out overnight and measure how much more oil comes out. So this time and yes I ended up getting it just over the full mark as I was experimenting with trying to get the level to the add mark after I had run it and then waited some and then added a bit and waited for a certain amount of time for it to settle to the add mark. I very well may not have waited long enough for that experiment but I got to the add mark, then dumped in a full quart and waited some and checked and then waited some more and it crept up more ... and then finally oops, it was slightly over full some hours later when it really had settled all it would. I find this engine sure takes time for the last bit of oil that gets poured in to finally make its way into the crank case. I can only guess at how much too much I added as per maybe a 1/10th of a quart. I had poured in 8.5 quarts going by the quart containers as per 8 quarts and 16 us ounces. I was shocked at how much this was off compared to the prior oil changes and if those larger jugs and they are not marked accurately enough or they contain slightly more than what they say, or the drain time factor made that much of a difference. But I know on this forum there have been others who have said they have put well over 8 quarts in their L8T and now I have also going by the Amsoil true quart containers. Its a confusing convoluted mess up here in Canada with some oil manufactures packaging is in true US quarts, some is also in true US quarts containers on an even number of quarts but also marked in liters which becomes the odd ball volume of a fractional amount of liters. Then there is the Liters only containers, no US markings as its a true metric container and only measured in Liters to an even number of Liters. But remember we used to have Imperial Gallons and Imperial quarts as well !.

      Holy smokes. Clearly not a deal on that truck. I just mean in general, matte or painted trim is becoming more normative than chrome, but I know the Black Optics packages on various vehicles are being sold as uplevel trims. They look really good, but sheesh. It's just paint and plastic.

      I Wouldn't Know Where to Begin    Oh I know where I would begin but I'm just one of over eight billion people on this rock. Eight billion versions of where the goal post is. How large it should be. How far to kick from. What ball is the right ball. Elevation. Age.....are you getting the point? It isn't about disagreeing with one individual. It's about agreeing only with one individual. One's self.   Agreement comes when multiple people hold the same point already. THAT is the goal of an education. Building the Social Contract. That thing that allows us to all read this sentence. We've agreed on the alphabet and how to arrange those letters into words we agree upon whose meanings hold true for everyone entering into that contract. Those words arranged into a sentence form an idea and several sentences strung together in a paragraph convey an argument for or against or inform the reader of a state, condition or perhaps reveal a things nature. Paint a word picture. Make oneself known.    This contract is not limited to words although they are often explained by words. Things like numbers and their usefulness. Physics, Chemistry, Medicine, Music, Art and so on.    The frequency of middle C (C4) is 261.63 Hz is a first principle. We build on that to make music we all can enjoy even if we all can not compose or play. You don't have to master it to make it enjoyable and useful.    So why is the Beginning so difficult? Why is agreement so elusive?   Everyone "Signs" the contract (when receiving that education in obtaining it)  but fewer and fewer in this world have any intention of living by that contract. They find exploiting that contract more advantageous. Disruption. With intent. Without intent. In Ignorance. In your face. With a double dog dare you. With a hold my beer. In resistance to that contract and in spite how it looks on us. It permeates the very air we breath.    In this way the contract is subject to advantage. Abide by it when it serves you, disregard it when it doesn't. Unpredictable and self-serving. Corrosive.....Toxic........   It says a lot about a persons character to disregard the contract, the truth, first principles. None of it good.        ********************************************************   https://medicine.yale.edu/news-article/character-vs-personality-who-we-are-and-who-we-aspire-to-be/   Just an interesting article.
