I feel bad for this guy...

 

2010 Sierra, 1800 miles, towed into shop. Won't stay running. 5.3 V8

 

Tech gets job this am, found cylinder #4 no compression

 

Cause?? AFM lifters grenaded. Yes, with only 1800 miles

 

Fix?? New AFM lifters, all 8

 

This is getting way too common guys...almost every week now there is some type of AFM BS.....

The more I read about the AFM issues, the more I tell myself "Don't you ever, EVER trade sell your 04 5.3"...now I just need to listen to myself... I have nasty habit of not keping vehicles more than a couple years....bought this one in Jan10, it will be paid off in May12. So if you guys ever hear me asking about new trucks... Please, I beg you STOP ME... it's for my own good. ;-)

Hey Stealth, looks like my suspicions are confirmed. GM must have switched suppliers or relaxed quality control on the new AFM lifters. This explains more incidents with them.

 

Can someone tell me if the new AFM lifters are made in China? It should state so right on the box, right next to "Genuine GM" POS, err, part.

 

If GM keeps this up, they will shoot themselves in the foot once again.

Stealth, just for info, how many hours does it take to replace the AFM lifters? What would be the total cost of this repair if one was out of warranty and had to pay for the repair? It was mentioned that cylinder heads must be removed to replace the lifters. What about flushing the engine to remove small pieces of disintegrated lifter? Is there a procedure for that too?

PLUS ONE

 

120k, no issues. Currently ~8600 miles into a load of oil, has used maybe 1/2 a quart in that time.

Are the lifters a part that is covered by the 100k-mile powertrain warranty? May be a stupid question, but I've been dead wrong before over what is part of the "powertrain" according to vehicle manufacturers.

Funny thing is..........we still haven't seen one issue yet with lifters at our place :fume:

I'm driving a 2010 loaner Silverado while my 2008 Sierra 5.3 is having new lifters and a new camshaft installed. The 2010 seems to be doing well. Dealer has had my truck for three weeks. Dropped it for an oil change and to see if they could figure out a rough idle issue... Would have gotten it today but my tech is in NOLA for some training.

 

I'm glad to know it's part of the 100,000 warranty. I've got 32.5k on it now. Was about to start looking at the 6.2 or an F150. I generally look at vehicles like I do my guns. If they fail once, they'll fail when you need them. We'll see how this fleshes out at the dealership on Sat.

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
