What do you guys think ? 65 psi for cylinder 5 I know that is low but is it fixable?
i am a little confused. they say relative compression was equal across all the cylinders, were ALL the cylinders low compression?

But yeah, generally if even 1 cylinder is low compression, the best option on an ecoboost is to replace the engine, time & $$$ wise.
The power of an oscilloscope. This guy walks you through basically what the dealership did.

Can you post a video of the engine cranking, you can hear that low of a compression pretty easily, and assuming the battery is good at the time of the test, figure out if there IS a problem even without scoping.
Get a second opinion as always...
oddity :: equal across all cylinders may have been a typo ... but when my mechanic did a compression check i got results for ALL cylinders independently rated not just one.
What happened to the fuse? report lists it as missing .. ?
Anybody know any good places I can get a engine from so I can swap the one out I have now ?
LKQ, car-part.com, etc.
How do you know if you have a oil cooler or not ? There is two different Types of engines
You have a 2010. Your MKS does not have an oil cooler.
But that said, an oil cooler can be easily retrofitted if you so desired

Ok just making sure just don't want to get the wrong one
Technically, any engine from the transverse 2010-2019 family will fit, but there will be some (not major) differences when you cross model lines. Especially if you decide on a Police Interceptor engine or Explorer engine. Easily overcome, but just to be aware.
I got it .... just want to get the same one for my year model so it's no confusing
