Have any of you guys purchased an engine via Ford Parts? What type of quality our we looking at with those engines offered? Factory quality?

Just fords remans, which are good.
You can get it for less from your parts counter at dealership. They will discount it a few hundred. My parts counter offered me 3350, I think online was 3750. An installer probably get full 20% off, so they can mark up.

Its a reman engine. By AER, not an all new engine.
Look at ford reman videos on youtube..

Ive got AER engine , not thru dealership, private install shop. I think it was $2800 ish. no problems at 31k. May be different from the ford one, dont know. But came with motorcraft plugs and tstat. Did not come prefilled with oil, but my installer uses different oil for break in for first 500 miles anyway,. And said no synthetic for first 9000. So I wonder about the ford shipping with 5w20 synnthetic blend motorcraft oil.

Way i understand it, synthetic slipperyness can cause crosshatch edges to be burnished over, reducing oil holding ability, instead of properly worn in to rings.

I wouldn't of purchased an engine from them if they said that. Their engines can't use the recommended oil for 9000 miles, what crap engine did you buy lol ? Unfortunately, sounds like you got a 50,000 mile motor special. Like they are trying to devise ways to get their cheap engine past warranty. Someone BS'ed you...that sucks. Hope I'm wrong in some way lol. Synthetic is designed to lube everything and keep them clean..less build up and blocked passages. Just saying 9000 miles, are you sure ?

In my own reading, I found their recomendations to agree with best rebuilders. Theres lots of technical articles and studies on best engine breakin lubrication.

The installer installs many engines and provide comprehensive 12 mo warranty initially, After that you must deal with engine mfg 3yr/100k warranty, which pays lesser labor, wont include fluids, etc, may want to want to examine a failed engine first, etc.

I recall one study toyota did linking synthetic with early camshaft failure. I recall another with micrograph pics showing eges of crosshatch extruded over the valleys by use of synthetics. Parts have to lap together, synthetic does prevent it from happening properly

These were reccmendations of the installler for their comprehensive warranty, not the engine mfg for theirs. They might have said 6k for synthetic, and i didnt switch till 9k.

I take some back. Your builder is most likley on the level for a build of that nature. I was skeptical after reading and listening to lecture about what it takes for Ford to recommend a formulation. It revolves around wear ratings... side effect improved mpg's which makes sense. What I'm saying is there isn't a break in formulation that involves that kind of mileage from the manufacturer (Ford) or any of them that I'm aware of. Their engines are beyond that break in stage before they're installed. I hadn't thought about that.

Yeah, I suspect all new factory engines initial run-in occurs at factory.

I know my installer used a break in oil with some additives for first 30 min or so , then changed it. added new oil , did road test, and said to change it after 500. Then again at 1500, then 3000, then 4500, then good to go after 6000 .

All I can say is no problems.

You can run synthetics right after initial break in. Never had a problem.
