Wait a minute. You bought one that you had some undisclosed issue with you don't feel is relevant to share...and then went out and bough a second one just like it? Reeeeeaaaaally? You hated it so much and it was such a big problem that you bought a second one? What the.....!! 

 

And wrap that all up under the heading of science?  

 

Smells of stockyard on a hot day in Oklahoma. Or just irrational. I don't do irrational 'me too' babble. 

 

What's the matter?

Why are you getting all "emoticonal"?

 

so long

Thanks Grumpy.

Pay me now or pay me later comes to mind.

Well maintained, not abused it will last if you didn't get a lemon IMO.

I have witnessed first hand people who mistreat the vehicles and then complain that it's a piece of junk. Never considering they had a hand in it's problems. 

 

 

Fram commercials. Yea, I remember those.  That was awhile ago. 

 

( a rant) This emissions and mileage thing has been a frog jumping half way to the wall of dependability/reliability for quite some time. Metallurgic technology advances haven't moved as rapidly as the destructive forces of heat and heat seems to be Detroit's favorite tool and with sound scientific cause. It lowers Nox and viscosity. Keeping the current technology alive and well is a combination, as you've learned, of controlling the quality of the fluids used to cool and lubricate. How long they are pressed for service, how clean they are kept and most importantly the temperatures they are allowed to suffer. That last ones primary lever is load. If you need to load it more than heat says prudent then add a cooler or two. Lower a thermostat setting. Add a fan. (rant done)

 

True story. I run a 2005 HD Electra on 40W. I also added twin coolers that hold oil temperatures to 90F plus ambient. The cam chain tension assembly in these has a know planned failure of 35,000 miles. The factory recommends 50W and preplacement of tensioners and chains every 30K. Cost about one grand.  This is an example of a planned failure for profits sake. If you ignore this he chain fouls the backing plate pulling debris into the off drive main bearing and BOOM!!. I ran mine 45K and when pulled down for inspection the tensioners still had 95%  + of their original thickness left. In fact I gave permission to replace any other  parts not found to be inside new manufacturing tolerance. (this is a top end tear down if you don't allow pushrod cutting and I didn't) Yep a blank check to a dealership. Not a singe part was replaced other than gaskets and tension assembly. A factory HD TC88 will run between 240 and 310F bulk oil temperature on a 90 F day depending on how hard your hammering it. I run 190 F on that same day no matter what. I did the Dragon on a 95F day in third gear never exceeding 40 mph under as much throttle as grip would allow and never broke 200F. The two other bikes with me were both over 300F. Deals Gap 318 curves in 11 miles.  Heat is a killer even with great oil.

I think people need to realize "cost cutting" is absolutely necessary today, as to "build em like they used to" would add quite a bit more to the price. This is true with everything in this disposible society from washing machines to the hvac on your house. 10 years is all anything is spec-ed for anymore because no one wants to drop the amount of money it takes to make something truly last. We find our earning power stagnant in this world because the rest is catching up; were still better off than most...

To the lifters I say this: tune out afm, keep adding oil (its cheap) till they fail, then rebuild better. Most of the problems people have are caused by the time they waste worrying about things they cant change...

I'm trying to think of an example where that might be true and am coming up empty. The squeeze on the families buying power is just as prevalent in non manufactured goods and services. It doesn't cost one red cent more to design a thing right as it does wrong. The cost of heat treat is the same for 62 RC and it is for 55 RC. The cost of steels and alloys properly selected are a wash. Fit and finish is head a shoulders above 1950 levels as is motor life spans.

 

However the 4-5-6 clutch packs in the 6L80E is a great example of stupid is as stupid does. The design is flawed. The apply piston fails to support the clutch discs fully. The cost of the properly designed parts from the aftermarket are cheaper retail than the flawed design factory original replacements. Cost to the consumer is not the issue. Greed is the issue. 

 

US buying power is down 40% since 1960. Inflation has out stripped earnings as steady and as slowly as a Boa eating a rat for five decades plus. that is not the result of anyone's necessity. Just plain old greed. Frogs boiled slowly don't notice their dying but can be convinced their not in danger by their own gullible senses.

The biggest factor IMO.

 

GREED 

greed

ɡrēd/

noun

 

1. intense and selfish desire for something, especially wealth, power, or food.

    

   The biggest factor in our world today. From the small business owner to the big guys.

Before I had the issues with the lifters in my truck, I would average around 17 mpg, according to the DIC.

Since having the DOD/AFM kit installed and turning the AFM off with the Diablo tuner I got, I'm averaging about 18.5 mpg

I have a 2011 Silverado with 5.3L. at 75,500 miles I had no issues and averaged just above 17mpg. At 76,000 miles the check engine light had a code of P0305, which is misfiring on #5 cylinder. I have followed all of the manufacturers' maintenance requirements including the oil changes to the specs.

Auto shop opened the manifold on the driver's side and it smelled like a dead animal, oil had silver specs and the lifters were worn so much that they would not hold their position. Seriously, disappointed in the 5.3L engine with the fuel mgt system.  I am glad to hear about your success. I need to pursue the fix.

When did GM change out the lifters in their trucks to prevent them from going out? or are they the same lifters that were in the 2008 Chevy Silverado?

Did you ever get answers on this? I have failed lifters on my truck and it needs a new engine. Trying to figure out how to avoid this in the future.

Rebuild the engine using non-AFM lifters, cam, etc
