2005 6.0 spark plugs coming loose

[Jer-Z-Devil]

Had plugs put in about 30k ago. I was checking another issue and notice one of the wires moving. In all 4 plugs are loose.

Any thoughtsm

Did you put them in or somebody else?

Dealership.

Can you tighten them or are the threads stripped? Either way Id call that dealership and let them know. Don’t run the engine if they can’t be tightened. Either they didn’t tighten them, they over tightened them and stripped them, or they were already stripped out.

Sounds like they did each bank by hand and then forgot to tighten one bank.

I'd call the dealer and see if they have any resolution before you touch it. If the threads were damaged on install/ are damaged now from them moving around, you don't want to be the one to **** with it and have to pull and replace the heads.
