2011 F150 5.0 KNOCK Cylinder Distortion/Piston Slap Options

I posted this in the 09-14 forum and got some views but no responses so I thought maybe someone in here had experience with this:


"Hey Everyone, I'm new to the forum, not long ago purchased an F150 truck and I love it except for one thing.

It's a 2011 with the 5.0 coyote and I have diagnosed it to have the cylinder distortion issue on #3 causing piston slap (has knock when warming up). No other issues yet as it only has 68k miles (no excessive oil consumption, loss of power, misfires etc.).

However, I do want to be prepared to take action if/when judgement day comes and it loses cyl #3 as it is out of warranty (unfortunately purchased it this way, relatively quiet knock most of the time).

So my first question to anyone who has experience with this is, is this a longevity issue? Will it ever affect my truck in any other way than a sound? I believe the only way to fix the issue for good is a new engine and I really do not want to shell out 3800 for a brand new short block from Ford plus labor so I would be getting a scrapyard engine out of a wrecked truck. The question is, can I use an engine out of a 2013.5-2014 truck in my 2011 without modification to avoid my new(used) engine having the same exact noise when I crank it up? So in your opinion, what should I do with this thing? I love the truck and I'd want to fix it if I have to."
