Its an easy fix though, just buy a ford Coyote motor and slip it in! No AFM, much better engine, more HP and won't need rebuilt at 95k miles!


Eh, the Coyote isn't bulletproof. Mine has made a ticking noise since new. We have replaced a few for the same noise, I'm just waiting until the warranty is almost out to drop in a longblock.

Lighter weight, higher mpgs and squeeze the most profit out of every engine doesn't leave a whole lot on the table for the customer.

I've heard some really great things about the Johnson lifters from various performance engine builders as of late.

Supposedly, they really go out of their way to LOOK for areas/ways to improve on lifter design, strength, function, and durability, whereas other aftermarket performance lifter manufacturers merely accept the 'status quo'.

My shop does several AFM/DOD deletes a year on 5.3L/6.0L/6.2L Gen IV engines, Trucks/SUV's are TOO EASY! A good Tech can do it in 8 hours, To bad GM dealers have no interest in fixing these engines.


X2.

Sounds like an AFM catastrophe.

Just maintain it as normal with Dexos 1 oil, and consider ridding the truck of AFM or at least disabling it.

Was at a local trail that starts at a YMCA. Just got back from a 4 mile walk. G/F and I are sitting in the Ranger b/s'ing before driving off when I hear what seems to be a V8 thats making a bad ticking sound. Not a knock.. more like a tick or a clack. I look up to see a late model F150.

Since many people are clueless about their cars and since I know when I hear a problem (not a master by any means but ive been working on them 20 years now), I decide to walk up and talk to the guy. I walk up and the guy has a "[censored] do you want" look on his face as he rolls the window down. I tell him of the tick im hearing and that it sounds wrong. His face changes and he says its a timing chain issue; he says his warranty is expired and he doesnt know how hes going to afford fixing it. 2011 with the coyote 5.0, 77k miles. I didnt get into a huge discussion with the guy- I just wanted him to know in case he didnt. He thanks me for letting him know.

I drive a Ford, and I wouldnt trust a Ford modular V8 for s***. 96-2010 4.6l and especially 5.4l v8s blow spark plugs like crazy. 2004-2010 5.4l v8s had cam phaser issues that wrecked motors, though admittedly very frequent OCI spared some from problems. Then a Coyote with a timing chain issue that I heard and saw with my own eyes? Admittedly, ive heard good things about the Coyotes and maybe that was an isolated problem- but thats awwwwwful close to the cam phaser issues Ford has had plenty of...

Ill take the 5.3l and its AFM [censored]. At least with the GM I can proactively protect the engine by doing an AFM delete.

Im not trying to hate on you or anything- again I drive a Ford as a DD and have always been a Ford/Chevy guy- but Ford hasnt had the best record and certainly hasnt had the legendary performers like the up-to 03 5.7l or 6.0l cockroach v8s.
also Ford took money from the Government also. Google it. So you can drop the Gov't motors act. All three of the big three have issues. The whole brand war thing is pretty much pointless these days.

 

[dan_erickson]

I had a Grand Prix GXP 5.3L V8 with AFM.. oil burner pos.

Neighbor has a newer Avalanche and had to have the cam and lifters replaced before 100K.

Not impressed with GM AFM tech yet.

I hear this all the time and from what I see on the Internet, did Ford get a bailout or did Ford take a loan that they either have OR they still are paying back? Obviously, some things on the Internet are to be taken with a grain of salt, but I read where Ford put the brand names of "F-150", "Mustang", and the "Blue Oval" up as collateral for the loan. What did GM do? Did they even pay it back or was a large part of it forgiven a few years ago? Was a part of it written off?

Very true. They are all junk.

Yeah, well do not tell that to the 2010 FX4 5.4L I had that saw 15K OCIs with 0W-20 oil starting just past 100K, it ran like new when I traded it at 160K with 45% of those miles towing 8-9K pounds in all temperatures. While the early 5.4L engines had trouble with spark plugs blowing out and breaking off, Ford redesigned the heads sometime in 2008 and the problem was solved.

Yea GM paid what they had to pay back a certain amount which they did. There is a sum they didnt have to pay back. Like I said they all got money, leave the brand wars for Billy Bob and Cletus at the trailer park. Truth be told I was looking at Fords before I bought my current truck. Im just tired of hearing Gov't Motors give me a break.

 

[Blinker]

That generation 5.3 has an issue with the lifters. Have one in my family, brother was a GM tech at the time he bought it and his has the lifter rattle.

Your dealer probably replaced the engine due to convenience (5yr/100k mi powertrain warranty). Im sure the dealer could have fixed it, i doubt that the original engine "died".

 

[Blinker]

Sorry, I failed to read most of this thread before I commented the first time. It seems many others commented about the AFM and lifter issues with these engines. If you have a new engine I say enjoy it!

Then you have answered the reason why you are hearing "Government Motors" whenever GM is brought up versus Ford. There is a distinct difference in being given money (and having part of it subsequently written off) versus being given a loan that has been or is being paid back. Thanks for the clarification.

 

[69GTX]

Good stuff to know. I always figured it was a bad idea to deactivate cylinders in a V8 or V6. If I buy 8 cylinders I want all 8 moving whenever the car is running.

 

[dailydriver]

Yes, if I EVER come by an LT1 equipped C7, or 6th gen Camaro, this is the very FIRST thing that gets done to it (AFM/DOD hardware AND programming elimination).

I don't even mind hearing it from the Blue Oval, or Mopar peeps, it's just the Nippon/foreign nameplate buying ones that get on my nerves, since even their 'perfect' marques have all taken coin from either their own 'gummints', or OURS somewhere along the line, despite how much profit/reserve capital they make/own.

 

[Ojustracing]

I just went through a issue on my 2013 5.3 One second it was running fine next it had a misfire. Lifter turned sideways. I only drove the truck maybe 12 miles and diag time. The cam was smoked!!!! I can see someone drive for an extended time and put a ton of metal in the oil system. Leading to oil pump bearing issues rather quickly. The dealer fixed under warranty.

 

[15SilvyEcotec]

The dodge is also doing the AFM thing with the Ram trucks. I have a 2015 Silverado and would like to disable/delete the AFM but the why I drive it on a flat 55 mph road it saves on gas. The truck is a crew cab and will hand calculate in the 20's always.

They sell 40,000 units a month of these trucks Silverado/Sierra combined. The vast majority have the 5.3. I am guessing the numbers of failed motors you see pale in comparison to numbers sold and how many are on the road since AFM has been implemented is quite small.

Use a good syn-blend oil and change at 5 or 6 K, regardless of OLM. Use oversized premium filter like Wix/Napa Gold or Baldwin, etc. Napa Parts Store can look up a crossover to a larger filter.

Or, pull the screen and still do the above.

GM had some "soft" lifters and we are pretty confident that the dealer used OEM supply chain for parts... Lifters have been a GM bug-a-boo for a while now. They have three contract suppliers (Delphi, Johnson, and I can't remember #3). Johnson seem to be the best of the lot. But we don't know which you got, so do your best to keep them wet ...



A good filter is correct.....an oversized one will not make a difference.
