I have a 2013 screw 5.0 with 226k miles. Bought at auction, company owned since new. Had a cylinder 4 misfire code, replaced coil with no improvement. New plugs(they looked original) no improvement. Did a COLD compression check and got 90 psi in cylinder 4. All others are between 151 and 161 psi. I have an appointment for a leak down test next week as I don’t have the equipment to do it. The rough idle seems to smooth out a lot once it’s warmed up. My plan is to swap the injector someplace else and check compression again, and to stick an Amazon borescope camera down in there once it arrives. Otherwise it runs well.

So preparing for the worst I’ve been doing research. The question is always asked when looking online what the build date of the truck is. Mine was built in 6/13. I think the threshold is 3/13 when asked. Does anyone know what the difference is between earlier 5.0’s and later 2013’s?

When looking for used engines, can I also look at 2014’s?

I was told that ford had issues with exhaust valves deteriorating on the early 5.0 coyote and that it was fixed sometime in 2013. Is that possibly the significance of the build date question? Should I assume that 2014 engines do not have the bad valves in them?

Do you think that having both my heads rebuilt(assuming that’s the issue) is a waste of money if the bottom end is going to have 226k on it?

Used f150 5.0 engines seem a little pricey, even with over 100k miles. Where is the best place to find them?

Lastly, it drives fine around town, is this really an issue worth dealing with right now? The truck is otherwise is excellent shape with zero rust. But I’m moving across the county soon and would like to use this truck to pull a uhaul trailer.

Thanks

 

Rebuilding these heads is a waste of money and often not doable as the cams eat the heads. Used 5.0 engines can be expensive due to the demand for swaps. I have had good luck buying from LKQ and Reno Auto Wrecking on Ebay. Bought two engines for swaps and they were right at 2k delivered each both had under 100k.

 

Thanks for the reply.

It’s hard to find regular reman heads online too, they’re all geared towards mustang builds. Did finally find some but they’re $800+ a piece. Then I’d need new cam phasers, solenoids, timing chain(s), bolts, gaskets, and whatever else. Not very cost effective, but I could remove and install them myself without much issue.

There’s a 48k mile engine locally for $3200, maybe I should just pay it. Otherwise I’m looking at $2500+ for 100k mile+ engines online

 

Hey, I was just reading in another thread you commented on.... and you said an f150 5.0 up to 2017 would swap into a gen 1 truck as long as you used the original harness etc. Can you confirm that?

I’m still having a hard time finding a lower mileage engine for my 2013 on line.

Thanks

 

Yes up to 2017 will work, use the original engine harness.

 

Got this reply from another forum when I mentioned using a newer engine in my truck..

”I'm pretty sure you'd have to swap Gen1 camshafts and cam-drive components into a Gen2 engine before you could use it in your truck, the Gen2 engines have mid-lock phasers that your Gen1 PCM wouldn't be able to control properly. This isn't horribly expensive if you know it ahead of time, but it can be a costly thing to find out after the new engine is already installed.”

any thoughts?
