Anyone done it? Some posts say the valve covers have to come off, others say no. It looks like the are outside of the vc to me and removing the fender well is the easiest way to access.
Usually I can find lots of vedios of any repair, but can't find anything on 6.7 glow plug change

 

Bob, I know from your other thread you are contemplating changing out the glowplugs based on that TSB. Please do some googling on that TSB, as I am 90% sure that its the valve that takes the glowplug out. Ford was telling their techs to check the glowplugs for damage caused by the defective exhaust valves in those early 2011's. I could be wrong, but would hate for you to spend $$$$ on new glowplugs unnecessarily.

 

GPs are supposed to be changed every 100k miles and a different tech recommended 60k miles on the 2011s...

 

I have done a lot of research and I am coffident it is the glow plugs are the number one problem. There might be some valve seats that dropped also, but no hard evidence.
There are lots of info on the glow plugs braking off and taking out a valve when it does. I am going to at least look at them, but from what I have seen 100,000 mile replacement is recomended.
I don't buy off that a piece of the valve brakes off without any warning. I can see the stem braking off suddenly, but not a section of the valve head. There would have to be a crack first, and that would cause a hard miss. You would notice something wrong first. There are lost of pics on the intrent showing damage from broken gp. Depending on where it is at TDC it could take out a valve easly.

 

I stoped by my local ford dealer today and got the oases report. I asked about the problems with the 6.7 and either valves or glow plugs. There where aware of the glow plugs braking but the have not seen a problem with the the valves. The service mangers said the have not seen any 6.7 engine falures from either the gp or valves at there shop.

 

it is the valves that take out the glow plugs.


2 piece valves.

 

What would cause a glow plug to break and fall into the cylinder ???????

 

Where do you get this info? I have looked all over and the majority show the glow plug being the problem. I have seen nothing that shows the valves are two piece.

 

My understanding it they are ceramic. And some of them where falty and would crack frome use and then brake off. I see no reason NOT to pull the glow plugs out and check them. Like I posted earlier my dealer did acknowledge the glow plug issue, but never heard of a valve issue. I have seen a lot of pics on the internet wit damage from the broken gp and no broken valves.

Thank you. That is about what I thought.

 

That glow plug tsb that came out was easily misunderstood and not explained fully by Ford. If you do some more research on Ford forums, many senior techs have come out and explained this in detail.

Ford explained latter to their techs that asked, checking the glow plugs condition was the easiest way to let the tech/Ford know what the state of affairs was inside the combustion chamber.

The engines that suffered from valves breaking/dropping on the early build 6.7 2011 was what Ford was looking for with that glow plug check tsb.
Ford did not want to pay Ford dealers for taking off heads to find cylinders destroyed from dropping valves that were a problem in the very early 6.7 builds. So a much easier, cheaper procedure, was check the glow plug. If the glow plug was damaged, it meant the cylinder was toasted from valve debris bouncing around in the combustion chamber.

Take it or leave it, thats the bottom line. Here is a senior Ford tech explaining it...

People make mistakes and misunderstandings. Unfortunately this misunderstanding goes on till this day, some techs still don't understand, sad. This vid is a great example of this misunderstanding...
