has anyone had experience changing engines on the 2012 f150? done plenty of older swaps but want to know what to expect with this one. Ecoboost blew because of an MSD plug so warrantee is not covering.
You blew a motor because of a spark plug? There's waaaaay more to this story. Warranty should cover it, assuming the spark plugs are materially equivalent to factory (Magnuson Moss).
I think I'd be getting a lawyer and going after MSD. Unfortunately, I don't think you're going to find many people who have done an engine swap on a truck that new.
Direct injection engines are much more sensitive to spark plug heat range and design. Op's description of the failure, while brief, is very plausible.
Op, have you done any other mods, tuner etc?

If loss of spark is going to hydrolock my 3.5L, I have one for sale.
At least it would cause a mis-fire condition setting a code. I can't see the cylinder filling with gas because of lack of spark. I would expect the PCM to detect that and shut off that injector.
Unless a piece of the plug was knocking around in the cylinder and broke the injector. THEN I could see that possibly happening.

If the injector was broken and filled the cylinder, the compression stroke could cause a hydrolock condition, but I'm not sure it would happen without the broken injector. Why would the PCM continue fueling a cylinder it knows isn't firing??
The people here are primarily interested in protecting the reputation of Ford and ecoboost. They don't seem to know a whole lot either. Take off your shoe and ask it...I'm kind of kidding, but I would hope you could be assumed to be honest and get some help.
I have read that the MSD plug are known for this happening. Motorcraft SP534 are what everyone is saying to run. Also having weak spark from bad coils doesn't help. I don't see how a cracked plug porcelain can cause this damage....but I guess it did. Hope this doesn't happen to anyone else!
