pulled engine pre-installation checks?

[stuchman1]

Hi everyone,

First-time builder and we've received a pullout gen 3 Coyote that some of you have advised me on through other posts already. Thank you.

A bigger picture question has been running in my mind - what sort of checks should we do now that we have the engine? I bought this one based on forum advice on what to look for - it's from a 2022 Mustang that didn't have a front impact, it only had 2k miles on it, it looks fine visually, the part shop has a good reputation online and they're local so they know I know where to find them ;), and it has a 90 day warranty so we're working hard to get it installed and running (i.e., tested) before the warranty expires, so we have recourse if it's a dud. Unfortunately they didn't get video of it running before pulling it.

Are there other things we should be doing to make sure it's good before installation? I'd hate to go through all of this just to find out it's a bad engine when it's in and we turn the key for the first time. The only thing that comes to mind is compression testing but that seems almost silly on a car with only 2k miles on it.

Advice appreciated!

As a result of it being in an accident, even though it wasn't a front hit, I would check closely all over the engine for any damage, i.e., engine mounts, transmission/bellhousing mounting bolts, any other exterior mounting items for cracks or bends. I have built multiple cars with junkyard pullouts and even though the accident was minor and away from the engine I still found damage most likely from a quick stop of the vehicle and momentum of the drivetrain. Otherwise, the engine should be in good shape with such low mileage that doing exploritory into the engine isn't warranted.

Thanks!

You’re doing the right thing by testing it out ASAP. Check the oil level and “age,”. It should look new since it only has 2k miles. Might want to replace the oil since the break-in should be done.

I would also have an OBD II reader handy so you can check engine performance and read any codes.

What are you doing for the ECU, etc?

[stuchman1]

We've changed out the oil pan already so the oil is out. It was pretty dark, though reassuringly no metal shavings or anything! For ECU, we did the usual purchase of the ECU from Ford Performance to replace the stock one. Good advice on OBD reader!

Good grief, it's a 2000 mile engine. Change the oil, stick it in the car and drive it like you stole, end of discussion. :rolleyes:

[stuchman1]

LOL thanks Rich. Fingers crossed that it's just that simple! :)

[rich grsc]

It is. ;)

If the oil looks good then roll. As Rich said, drive it like you stole it! :cool:

My engine was very similar to yours. I did a careful once-over for damage and then followed Rich's advice (which is spot on). My engine did sit for about a year before I put it in - no issues. I know there is a warranty timeline to consider, but I would caution you about rushing to get it in and running. Take the time to do it right (and enjoy the experience). Getting the engine in and the first start are significant milestones.

Great advice James and everyone. Thanks!

As stated, just check all of the mounting ears / tabs. New oil and run it HARD!

Put the headers on to check for fit. Not usually an issue, but easier to address with the engine on the stand.
