Bulletproof Ford Engines

Ford 300 i6. my favorite car of the 50's is the 1951 Hudson Hornet with a 308 i6 engine. they dominated Nascar 4 years in a row.

I had great luck withe my 2011 F350 diesel...the first 6.7 ...why? I never drove it much 😁
Ford gave me the $$$ for the diesel with the $9k rebate
 
The Duratec 4 cylinder engines are about as bulletproof as one can get, with the 2.3l and 2.0 from the mid 2000's being super long lasting. These are Mazda designs however, so is it really a Ford engine? ( owned a 2003 Ford Focus with the 2.3l Duratec and it was flawless for 125k).

For Ford designs in the modern era, the 5.0 Coyote is pretty robust and reliable. The Gen 1 Coyote was good, but the Gen 2 is probably the best overall for robustness and simplicity.

The 3.7l cyclone and later 3.5/3.3 are also very reliable engines when NOT in a transverse layout. The water pumps were garbage but the engine itself is pretty much bulletproof. My fleet has 3.7l with over 250,000 miles and 10k to 15k idle hours and the engines are still running strong. The cars around them are falling apart however.
 
To the i6 fans, here is a 3 part series on a FI 300 Ford custom build...
No AI narration

 
I had a 200 6 in a Comet and it was the easiest car to service ever. Didn't have to get under to change oil and filter and good ride and gas mileage. I had Model A's and early Ford V8's flatheads and 292's and 332's and 255 V8 in a Fairmont 302's in econolines . All were good motors. They just had all the good design people retire or give up.
 
I also had a 200 in a Comet. I bought it used for my wife when we were first married. It was in great shape other than it had the rear pushed in a bit. I worked in my dads shop so I didn't care. Pulled out the dent and got a re-chromed bumper. Had about $250.00 in the car. Never had to touch the engine other than a bad coil.
 
Well they managed to screw it up on later years by using a fiber camshaft gear. The good news is after it blew out and you got towed you could put a steel gear in and motor on, because it was not an interference engine.
Unfortunately Ford screwed up a lot of things imo, which is why I'm done with them. My my E-150 goes that will probably be my last Ford.

And yet my 5.0 powered 2024 F150 is about as conventional as we can get today. Simple to service, known long engine life, smooth and good mpg. What’s not to love? No drama, no failing main bearings, no warranty replacement engines, no unproven tech. I don’t have the dual exhaust version, so the engine is pretty much silent, it’s not the V8 sounds that make this engine so good. It is the smooth performance.

I will probably put a tune on this truck once the warranty is up, mostly to eliminate the top speed limiter. But the thing runs like a champ and 400HP is plenty.

I'm glad your F150 is serving you well. My 88 E150 is still serving me well. I'll be sad the day I get rid of it.
 
I have had great experiences with the 302, 460, 4.6, 5.4 (2V). My brother had a '92 F150 w/ the 302 that you could just not kill! He never changed the oil in his ownership starting around 205k. He would add a qt of oil when he started to hear a "knock". Sold it with 252k and the motor still ran great. No issues with the 302 in my '88 Towncar either, although pretty gutless tuning in that one :)
 
Supposedly the 7.3 gasser can't handle extensive idling due to 8 psi oil pressure while in that mode....

Okay the 6.8 L v8 shows double the oil pressure in idle mode 16 to 20 psi... then I read it's 5 psi.. then I read 18 to 25 psi ... misinformation internet.... anybody know for sure?

We let motors blow for several years because of this?
 
A 1973 ---351 Windsor V-8. Could not kill this this no matter how hard I tried. I even re-purposed it into other Fords or Mercs with bad 351 Clevelands. The ONLY thing that went wrong with it was that stupid plastic coated aluminum camshaft gear. The teeth broke off and skipped time on me. Replaced it with a steel one. I beat the crap out of that engine. Then I switched over to GM for some reason. I must have blown 5- 350 Rocket V-8's. Beat them too. They couldn't take it. Always threw a rod on me :(.....
 
Without watching the video, the 300 I6, probably one of the most reliable engines they ever made.
Is the 300 I6 the same as the 4.9 I6? My friend sold a van with that engine to another friend and a month or two later the guy stopped by and the motor was making noise...my friend checked the oil and there was nothing on the dipstick....he added a few quarts of oil and it quieted right down and ran for many years after that. That was a great engine.and strong engine.
