spark plug prob

[coolvxss]

Today i decided to change my sparkplugs for the first time since i got my car. it was all good till i got to the last plug. the numbnuts that owned the car before me threaded it and cant get it out. well i prob could but its realy realy tight and im scared that if i get it out i wont be able to get another one in. does anyone have a solution to this prob that wont cost a fortune? cheers

it's a steel head champ, the likelyhood of you striping the thread out is not very high. removing the plug is easy, you spray the spark plug with some inox, and let it sit for a few minutes, and undo it. if it does snap, go and get yourself some easy outs, drill a hole in the center of the thing but not to far down, then you insert a easy out into the spark plug and it will come out.

as for the re-taping the thread, well that is the fun part, mainly cuase when you re-tap the thread some of the old thread will fall into the bore, and it's nasty when that happens, if you are unsure, i would take it to a mechanic, either way, it will cost some money.

yeah i gapped them all to the right size its just this one that is stuck thats a real problem. i dont have enough money at the moment to i cant take it to the machanic. you got any idea what it will cost to get it fixed?

Most mechanics shops will have a thread chaser made for this problem.As they dont actually cut the thread the amount of filings that can get into the bore is minimised. It should take around half an hour to do.
