My 05 Ford Focus was due a service, was running fine but due a service. .......to say they had a problem and that the spark plug was stuck in the cylinder head. (Means nothing to me)
Id agree with PetrolHead
The plug most likely seized in the head and broke leaving the threaded part of the plug left in the head. Or the plug was overtightened and the plug thread in the head was damaged. Either way the had would have to come off to drill out the old spark plug end or fit a helicoil the fix the broken thread. The head would then probably be skimmed. The engineering shop would charge 200-300 alone for this job. So your left with 800 for work done. So if your garage spent 10 hours at it that would be good time to do the job, If one exhaust stud broke, as they do it could add a lot of time to the job. Plus they would have parts
Oil
Oil Filter
Coolant
Head Gasket
possibly head bolts and other gaskets.
Hopefully they also changed the timing belt while it was off as this would probably cost you 600+ anyway.
Get a detailed discription of the problem and what was replaced.
I'm still sticking to the incompetence of the mechanic, he botched the job and bought an engine.
Petrolhead, think youre being a bit harsh. I dont understand cars, thats why I left it into a garage to be serviced, thinking it would cost 150-200e . end up with a bill 5 times that
As I said above, there are a plethora of reasons as to why a plug gets stuck.
Give me 3 reasons.
1. Water leaking into the spark plug hole (from windscreen washer water hose under the bonnet)
2. Oil leaking into the spark plug hole and onto threads - I have been told that the threads should be dry not oiled as the oil on the threads can cause them to sieze. A poor seal on the filler cap and unsteady hand topping up the oil can cause this.
