Can anyone advise me re the following.T he number 4 spark plug bore in my cylinder head threads are damaged and I cannot screw a spark plug in.Is it advisable to have it either rethreaded or the cylinder head removed and repaired,also what is the cost I can expect to pay?Your opinions would be appreciated as my knowledge of vehicles is very basic.Thanks

 

for the cost & the quality of what your going to end up with.

you may as well just replace the head. I'm sure you could pick one up pretty cheep & that way u don't have to worry about u'r spark plug shooting through your hood!
