REVIEW: Everything Wrong With A 5.0 Coyote Engine

What could possibly be wrong with the Ford "Modular" 5.0 Coyote engine?

We cover all the common problems with the 5.0 Coyote Gen1/Gen2/Gen3 engines, and compare it with the Boss 302 as well as its Modular predecessors including the 4.6 / 5.4 2v 3v SOHC and 4v DOHC variants. #RichReviews #EWWengines

Always good to hear stuff we missed. If you have experience with these engines, leave a comment!
**Edit* : We're seeing a lot of the same comments about synthetic oil... It's fine to disagree with Scott, just want to make it clear that Scott isn't diagnosing this engine failure as a synthetic oil issue, and neither of us is recommending you run conventional oil in these engines or any engine made to run synthetic. Always run what the manufacturer recommends in your vehicle. Scott also never said synthetic is "inferior" to conventional oil, just that longer drives are much better for these engines in the long run. He also never said synthetic oil is what caused this engine to blow... He said it leaves a tarnish and he has seen crystallization more common in engines running synthetic than not. Not all synthetics are equal, not all bearings are equal...your experience will vary. Go ahead and debate these points, but we didn't speculate on what caused this engine to fail until 22:09 and ultimately we don't know the history or what actually happened. Change your oil and do regular maintenance guys. Again, we make these review videos to discuss engines and their problems as a resource for used vehicle buyers and hotrodders looking to rebuild these. If we didn't like the 5.0 we wouldn't put one in a Bronco...

My takeaway from this video: change your damn oil.

[rileshardwood]

From my time working at Ford in NZ I have to say the 5.0 is probably one of the most reliable and problem free engine we get

[blackbeargear]

5.0 are bullet proof as long as you change the oil frequently. I've seen some with 300k and no issues.

[nickthrane]

"Oil is cheap. Just do more oil changes" BINGO!

[tommybarlow]

Rich I’m sure a lot of us would love to see a 3.5 ecoboost torn down. Lots of questions surrounding longevity of small displacement engines pushing big numbers for long periods of time. Love the channel and content keep up the good work!

[kirkniese]

This was the best teardown I've ever seen! The candid conversation between you guys is much appreciated!

[praisejesus]

I hate to be that guy but as a Ford Tech of 20 years there was a lot of misinformation shared in this video. Put synthetic in your Ford. Dont use FRAM and you'll be good.

[gtspeed]

Good video. Biggest take-away: more oil changes are better than less, regardless of oil type.

[bug]

for years n years mechanics have been sayin "oil is cheaper than motors"

[travelingman]

I just got to say... Taking the time to make the video I'm sure everybody appreciates very much. I just have to add; the video hits differently knowing you own a 5.0 f150 and want to see deeper into the engine and your taking it apart right before our eyes! Great video!

[taylorcarson]

Seen a few 5.0 work trucks with over 350k still going good when we got rid of them

[cujet]

As an ex Mobil Oil employee, I can state with authority that Mobil's testing shows nothing like what you see in this engine. M1 synthetic oil, changed regularly, will result in clean engine internals. Period, end of story.

[jvepps]

That engine probably had its oil changed a hand full of times in its life.

[korex]

Im an apprentice working on ship engines and I absolutely love the channel. The videos at the machine shop are SO interesting, especially because it's exactly the same stuff Im learning on a small scale, keep the vids coming!

[abrahamsanchez]

Sorry, I don’t agree. The 5.0 might be the best engine ford has made as of late. The owner of this engine definitely abused it.

[tigerseye]

I've used Mobile One full synth. in my '89 Dodge 2.5l turbo since I bought it new. I change at 8500 miles. Those little Chryslers were noted for eating head gaskets. Iv'e changed 5 of them in its 31 year life span ( 300, 000 + miles ) It gives me a chance to check out the head/valves/cylinder bores. Even though its turbocharged, the engine is always clean inside. No smudge, sludge, or coking. Turbo has never had an issue.The cross hatch hone pattern is still visible on the cylinder walls. Your buddies assessment of full synthetic motor oil is WAY OFF BASE. Please let him know he is spreading false info on your channel. I'm not affiliated with any oil company. I base my statements on decades of experience working on my own vehicles. Your friend bases his on assumptions. Love your channel!

The discolouration between different banks on a V configuration engine is due to the PCV gases traveling from one bank, with fresh air from the intake tube, through the block to the other bank and sucked out through the PCV valve into the intake manifold. I've seen this especially doing timing chain jobs on GM 3.6l high feature V6. It bakes the "hot bank" with the heat from the "cool bank".

[jimh]

Just FYI, Ford's first aluminum 32 valve DOHC V8 was the 1940 through 1950 GAA engine, 1, 100 cubic inches. Initially designed as a 60 degree V-12 for aircraft, it was cut down to a V8 for use in the Sherman tank. So Ford had some experience when they developed the mod motor. There are still a few GAAs around, I've seen some YouTube videos of them running on stands.

[Shanidar]

Oil has a finite capacity carying for holding dissolved pollutants...exceed that capacity and sludge will stick everywhere. It doesn't matter if it's synthetic of mineral.
This dude is making too many assumptions about the engine's past life.
