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?

Causes of 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.

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

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 .. ?

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.
