With a brand new Ford crate motor I am not going to worry... I gotta warranty with it!
Thanks that makes sense. I'm pretty sure since mine has 112k miles it's good and broke in.

So I'm up to 130k on mine -but this is the first I've heard of this issue. I just got a quote from the dealership for changing out the glowplugs and it came in just under $1000. Generally you guys dont think its cause for concern since mines "well" broken in?

Glow plugs are less than $100 for 8 new ones online and the process doesn't seem all that complicated.
Maybe check out some Youtube videos, you may be able to do it yourself?

I might end up doing the same just to be safe.

I plan on doing this myself and I just answered my own question in another thread about this issue... Just have to make sure you buy the right plugs for your truck for your year..

Didnt the tsb and previous posts indicate that the valve was the issue not the glowplugs?

Valves failed and caused a collision with the glow plugs which shattered.

Ford fixed it with a 2 prong attack...

1.) Better QC with the valves
2.) Moved the glow plugs farther out of the piston so that in the event of a failure they wouldn't break off.

If you have old glow plugs you can't use new ones. The threading has been moved.

If you have old glow plugs and your truck was produced after 4/2012 you should have the newer batch of valves so it's not a problem.

If you're still concerned about the glow plugs you can look at my post history where I had to replace one to find the ford writeup. You go in through the wheel well to take the plugs out.

My truck is a 11/10 F350 (2011) so that would mean that I would have that problem. I do however have the ESP Warranty for the next 4yrs or 48,000. Along with the ceramic bearings in the turbo and the High Pressure fuel pump also known to detonate, it's hard feeling confident about this year. I plan on using the truck to tow a food trailer in the next few years. Seems like a lot of upgrades on top of an already pricey truck....grrr.
