Ford 2.7 vs 3.5 vs. 5.0

the wet belt and it's non-keyed and free-spinning crank drive pulley are surreal.

Ford 1.0 Ecoboost is cool on the paper, but he quickly proved it is not the case. That 1.0 will be cool in tiny buggy build or whatever, but the reliability and durability are terrible.

This is what you get when you let textbook engineers run shit.

"our simulation and testing determined the crank pulley won't slip until 200% it's designed torque and the belt won't drop below 80% it's initial strength until 180% of the service interval"

"no our simulations didn't account for high temps from hard use, wear and tear or extended oil change intervals, why would we do that? Customers aren't supposed to be doing that stuff"

"we saves six cents per engine over a traditional double roller" (wet belts ain't cheap)

"of course we just assumed this will have the same warranty rate as the double roller, why wouldn't it?"

The hordes of europeans who will buy these because displacement taxes and ungodly expensive fuel won't care. They won't be able to keep the cars theyr'e in long enough to matter because the .gov will all but force them to trade in on something newer and sell the car into a cheaper labor market where needing tons of man hours to stay on the road isn't a big deal.

That belt shit is stupid. My 2021 2.3 EB has a chain, I saw it with my own two eyes. It also hits 105 psi oil pressure. It blew up the first mechanical gauge I put in it because it obviously over ranged it. Had to put a 150 psi mechanical gauge in it to keep tabs on oil pressure.

man that motor seems way more complicated than it needs to be.

it is how they meet the federal requirements... kinda cool they can figure out how to squeeze every last thing to make it all work.

That's everything made in the last 15-20 years. The last majorly beneficial thing to come from it was the 6 speed automatic transmissions, the rest is complication in the name of "efficiency"

i feel for you dealing with that everyday dude. that thing was an absolute mess of nonsense. the integration of the valve cover and intake manifold is what really set the tone out the gate.

the newest thing i own an 07 tahoe, so im living in the stone ages. really makes me want to just deal with the AFM and keep it simpler.
 
I think as this generation of technology ages we're gonna see a lot more spun bearings and "serious failures" because ain't nobody paying for a mechanic to R&R an intake at $100+/hr to fix a valve cover leak and other shit like that.

well if the the first step off anything beyond an oil change is remove the cab, things are going to become disposable. wild to consider the long term effects as you play that out.
 
The electronics that you can't easily replace with a used part will probably kill most new cars before anything else. The OEMs have started VIN locking shit so it can only be programmed to one car without getting into EEPROM work to recode or clone the modules. Then they conveniently can't get out stop making that part and your shiny new truck doesn't work anymore.

Finding that a lot of the early electronics for 80s and 90s cars are getting to be scarce and not a lot of demand for them to be remade.

I guess that extra 1 mpg is really helping the environment?:homer:

Yeah but most of those are really simple board level repairs provided they haven't been full of water or a capacitor hasn't leaked bad enough to ruin the board.

And a lot of that stuff wasn't super integrated. Can still be bypassed, removed, or redesigned and the car will still work.

Dunno so much about the last 5-10 years stuff.

Good motor for longevity, it's just a dog.

I towed with a 4.6 all over the east coast. It lived in 2nd gear. No tach no care. Sold rotted to shit with a broken digital odometer. Last I saw it was 215k.

You think it's a coincidence?

There have been intake manifolds blocking valve covers for 30+ years. What changed?

They added more shit you've gotta go through before you can even start on the intake.

The worst packaging solutions of the 90s and 00s are the new normal.

I like the newer plastic intakes without coolant passages.

I did a ton of those things. 3.8L GM's lower intake gaskets, plastic water elbows and upper intake assemblies that leaked by the EGR passage.

Ok im going to look at a 2014 5.0 4x4 150 tommorow with 167k on it. If it apears well taken care of am I asking for any imediate major problems? Does it have a decent likelyhood of hitting 300k?

I'd say no. My 2006 5.4 is closing in on 300K. I just decided to put truetrac in front and rear because the rear was slipping a bit. At 150, I did leveling when I needed shocks, I did rotors, and front wheel bearings. It has been a completely reliable truck for me. I think the 14's are even better.
 
I've seen a handful of 11-14 5.0s with valve issues around 200k but most seemed to have had the shit kicked out of them that entire 200k. 6R80 will probably need a lead frame sometime in the next 50k but that's not that big of a deal.

Damn, that belt was rotted at 90k and a couple years old. I don't see how these things are going to be around in 20-30 years.
