Who haz seen this before

[DEEZUZ]

And what caused it exactly and what symptoms did you have

 

[co04cobra]

What brand is it? How many miles on the truck?

 

[DEEZUZ]

Its a factory plug that was reinstalled into new heads. Had about 1000 miles on it.

Yes that is soot all over it

 

[co04cobra]

Only 1000 miles on the plug to?

 

[DEEZUZ]

Yup. I had to use vice grips to get them out. The truck starts like **** and Grey smokes likes all hell. Has a fuel knock on a few cylinder. We removed injectors tested them, perfect. Went to do compression test and couldn't even get these out of the head. Yes they were torqued upon install

 

[DEEZUZ]

I have never seen this before

 

[DEEZUZ]

This is #7. It had a positive balance on graph and a fuel knock that went away when injector was disabled. I replaced injector and same thing in a few miles.

Something muffed up with the sleeve? For combustion to get up that high I'd guess they weren't seating on the sleeve.

 

[DEEZUZ]

Thats my thoughts. Something up with sleeves. I'm just waiting for someone to PM me something and drop a name cause I need to see whose paying for what

 

[jr6968]

seems to me that the only way something like that could happen, would be if the sleeve wasn't seated properly. through a couple heat cycles, the sleeve moves and the glow plug loosens up.

New/reman ford heads?

 

[DEEZUZ]

Nope. I won't say whose heads, but not ford's

 

[reilly8282]

I know you didnt get to the compression test before you figured out the issue, but what did the relative compression test look like? Was 7 low?

 

[Zmann]

Nope. I won't say whose heads, but not ford's

so you didn't exactly answer the question new/reman Ford ?
so excuse Me if I am wrong
but if they arent "Ford" heads there is only one other brand that I have seen it's the Chinese head that Odessa/clearwater/ and apparently Quick tricks sells ?

 

[DEEZUZ]

I do not Know the supplier of the head. But it's not a Ford product. Nor any you mentioned

 

[co04cobra]

I've got a nice set of ford heads ready to bolt on for sale. :ford:

 

[DEEZUZ]

I do not Know the manufacturer of the head. But it's not a Ford product. Nor any you mentioned

well the ones I mentioned are apparently all the same overseas casting so I bet the ones you have are also

keep us posted

 

[ghohouston]

That is no bueno. I've definitely never seen that happen, but I would agree with what has been stated

 

[reilly8282]

How about some info, symptoms and issues. You said a fuel knock and what else? Was the relative compression normal? Would it only knock when warm, also why do you think a new injector masked the issue for 1000 miles? This is one of the first times I have seen you ask for help vs helping others, so I'm curious to see some more info about what got you stumped.
