I just passed 80k miles on my EB, and am averaging about 3500 miles/month now. Here are the issues I've had in my 80k miles:

1. Service AdvanceTrac Light - EPAS sensor is going out. Ford recommended I replace the steering rack, but I haven't, and now the warning has gone away for the past 5 months or so. I'll wait and fix as fail.
2. O2 sensor replaced - Ended up being a broken wire, but dealership incorrectly diagnosed and replaced the sensor first
3. Harsh shifting - a transmission reprogram addressed that early on, and hasn't been an issue since
4. Spark plugs - Replaced myself at 50k. I'll replace every 50k, its not really that big of a deal, especially once you lube up the boots with a lot of dielectric grease.
5. Coolant overflow tank leak - Dealership replaced the line connecting it to the engine, but I still have a leak, so I get to spend another $276 to get the tank replaced. Its going in tomorrow to get the new tank. I don't blame this as an EB issue, just a 'vehicle' issue.

Otherwise, I'm rolling the miles, putting about 8-10k per oil change. My plan is to trade in 2-4 years depending on how much the truck starts nickel and diming on repairs.

 

I'm another that's owned both engines...the 5.0 in my '11 and now the 3.5 in the '13. At 2K miles I had the CEL come on on the '11 with the 5.0..they changed an O2 sensor and 4 injectors to get it to clear. After that no more problems other then an aggravating knock from the engine. The '13 with the 3.5 has been flawless so far and now has close to 13K miles on it. Both are good engines and the only difference other then the sound of the engine is that the Eco pulls harder from 0-50 then the 5.0 did...and that's with a 3.31 rear instead of a 3.55 like the 5.0 had. I'm getting close to 1 mpg more with the Ecoboost so mileage is fairly close. Towing the same trailer with the same amount of weight the Eco wins hands down vs the 5.0 in the 0 to 50 mph run. The direct injection bug is the only thing that scares me and seems to be common in all engines...wifes SRX Caddy with the 3.6 non-turbo has problems also. I'm old school and years ago I would have never thought I'd see a 213 cubic inch engine move a big heavy truck like mine does...and thats without a tuner! Good info guys on this over beaten subject!

 

Ha sinced you asked for it. The Ford manual lists these as the engine control sensors on the current engines.

The 3.7 uses these sensors:
• Camshaft Position (CMP) Sensor
• Catalyst Monitor Sensor (CMS)
• Crankshaft Position (CKP) Sensor
• Cylinder Head Temperature (CHT) Sensor
• Heated Oxygen Sensor (HO2S)
• Knock Sensor (KS)
• Mass Air Flow (MAF) Sensor — 3.7L, 5.0L (4V) and 6.2L (2V)
• PCM
• Variable Camshaft Timing (VCT) Oil Control Valve — 3.5L GTDI and 3.7L

The 3.5 EB uses these sensors:
3.5EB
• Camshaft Position (CMP) Sensor
• Catalyst Monitor Sensor (CMS)
• Crankshaft Position (CKP) Sensor
• Cylinder Head Temperature (CHT) Sensor
• Fuel Rail Pressure (FRP) Sensor — 3.5L Gasoline Turbocharged Direct Injection (GTDI)
• Heated Oxygen Sensor (HO2S)
• Intake Air Temperature (IAT) Sensor — 3.5L GTDI
• Knock Sensor (KS)
• Manifold Absolute Pressure (MAP)/Intake Air Temperature 2 (IAT2) Sensor — 3.5L GTDI
• PCM
• Turbocharger Boost Pressure (TCBP)/Charge Air Cooler (CAC) Sensor — 3.5L GTDI
• Variable Camshaft Timing (VCT) Oil Control Valve — 3.5L GTDI and 3.7L

The 5.0 uses these sensors:
• Camshaft Position (CMP) Sensor
• Catalyst Monitor Sensor (CMS)
• Crankshaft Position (CKP) Sensor
• Cylinder Head Temperature (CHT) Sensor
• Heated Oxygen Sensor (HO2S)
• Knock Sensor (KS)
• Mass Air Flow (MAF) Sensor — 3.7L, 5.0L (4V) and 6.2L (2V)
• PCM
• VCT Variable Force Solenoid — 5.0L (4V) and 6.2L (2V)

The 6.2L uses these sensors:
• Camshaft Position (CMP) Sensor
• Catalyst Monitor Sensor (CMS)
• Crankshaft Position (CKP) Sensor
• Cylinder Head Temperature (CHT) Sensor
• Heated Oxygen Sensor (HO2S)
• Knock Sensor (KS)
• Mass Air Flow (MAF) Sensor — 3.7L, 5.0L (4V) and 6.2L (2V)
• PCM
• VCT Variable Force Solenoid — 5.0L (4V) and 6.2L (2V)

The EB uses 12 engine sensors (2 pressure, 1 air temp) vs. the other engines 9. Not a big deal.

Now go compare the extra moving parts the two extra cylinders on a DOHC V8. I'll give you a hint, it's 100+. None of the current engines is really simple; there are a lot of parts moving around to get the power we want and the emissions the .gov demands.

I've driven trucks with both engines and will echo what everyone else says. The 5.0 sounds great and makes good power when you spin it up. The EB pulls a lot harder especially on the low end.

4 valves
4 springs
4 lash adjusters
2 pistons
6 rings (3 on each piston)
2 wrist pins
2 connecting rods

You did say moving parts right? Hmm my math shows 24?

Even if you counted
2 keepers (halves) per valve and top hat
4 bearings per connecting rod (counting each clam shell half)
You're talking adding another 16 parts


Not anywhere close to your claimed 100+




As far as the EB you're also over looking the complexity of adding both oil and water coolers through the turbos. That's additional plumbing and connections that can/will fail

 

As for my choice. I wanted a lower optioned truck that was sub 30k

Haven't been sold on EB " technology "

When towing 8,000lbs+ I wish my 5.0 had a little more grunt in 6th gear, which is technically triple overdrive. It has no problems in 5th.

Planning on swapping to 3.73 (currently have 3.31) the dealer had my truck listed as a 3.73 optioned truck

 

You might want to look at an IPC and recount...
4 lifters
4 valves
4 springs
4 rocker arms
8 keepers
4 retainers
1 pistons
4 rings
4 adjusters Upon further review these aren't listed for the 5.0
1 rod
1 cap
2 bearings
2 rod bolts
1 wrist pin
2 wrist pin clips
4 valve seals

That's 46 per cylinder so there's 92 parts. Not counting parts like main bearings on the bottom end.

EDIT: Here's the 5.0 IPC from Tasca Ford Parts

EDIT 2: There's only 4 rings per piston and no lash adjusters. If I can't show a part number for it I won't count it.

 

Here we go!

~nvm - da Wookie already gave the math lesson, lol

 

i just bought my '13 f150 fx4 5.0 a couple days ago, but i was in the same boat as you for a bit, 5.0 vs EB. even though the EB is better for towing i will be doing some towing every now and then i still chose the 5.0. why? because i just couldn't bring myself to own a v6 truck... exhaust sound is a BIG + for me with my vehicles and since my previous truck was a 5" straight piped 6.0L powerstroke, a v6 EB just wasn't going to cut it.. ive owned my 5.0 for about a week now and i have 0 regrets.

 

Ah. I see.

The jury will disregard the testimony of this witness.

 

I can't really contribute, because I came from a 2011 3.7 n/a V6 (and a sluggish 5.4 2V before that), so my testimony is not really admissible either. But I just had to say this might be the finest EB vs. 5.0 thread I've ever seen around these parts. Classy thread, folks.

But if you must know, now that I've owned a turbocharged vehicle, I don't know that I could go back to natural aspiration. To be fair though, I've never even driven a new 5.0. I'm curious to do so at some point, especially in the new lighter '15s. But the turbos are a blast to drive and they pull hard.

 

I did my list off the top of my head while sitting at lunch at Chick Fila


Thanks for the bigger list, except valve seals are not a moving part?
And there are no lifters, or lash adjusters in the coyote 5.0
And there should be a wrist pin bearing in your list

So here we go:
4 valves
4 rocker arms
4 springs
8 keepers
4 retainers
1 piston
4 rings
1 rod
1 cap
2 bearings
2 rod bolts
1 wrist pin
2 wrist pin clips
1 wrist pin bearing
0 adjusters
0 lifters
0 valve seals

39 Total per cylinder


* If you really want to get technical, by definition a bearing is a non moving part. Same argument could be made for bolts
(I realize for the purpose of the exercise why they are counted, I'm just pointing out the irony)


** I didnt know Ford went to rockers instead of lifters/lash adjusters. Guess to move the cams wider to allow for VVT phaser?



Did I miss something? All in good fun and learning
