Good advice id try the second one its a chance worth taking the 1st will cost too much you could just put another engine in. i have a complete one for 250 lolThere have been many discussions on this topic and it falls into two distinct catagories. The head off group and the head on and hope for the best group.
1. Head off group. take the head off and then drill the plug out being careful not to damage the thread and then reinstall. This means headgasket, cambelt kit, headbolts so not a cheap option. This is the correct sollution to the problem and would advise you to do this everytime:thumbs:
2. Head on group. Drill the plug out with the head on. Then suck the swarf out with a straw attached in a lash up style to a hoover. Then start and hope that any left over gets either burried in the top of the piston or leaves via the exhaust valve. This is very risky and not really the ideal sollution so I can't recommend it. The swarf missed could get stuck on the valve seat and then you would bend a valve. However I have done this on my spider as the previous owner broke one off and just left it. It made a horrible tap noise for about 10 seconds and then cleared so I was lucky. If it had bent the valve you could always look at the fact that I would have had to take the head of anyway so changing a bent valve isn't the end of the world. Remember this is your car so I can not condone this second option and would advise you do the first one. But as it will get mentioned anyway you might as well hear it from me.
Good idea but the plugs are right down inside the head so it would be nealy impossiblejust a thought,but a mate had a focus with a similar dilemma,it was cured by welding a bolt(or nut,not sure which!)onto the remains of the plug and then undoing it,carefully!no taking head off or swarf in the engine.......think the heat from welding helped loosen the plug remnants,too!as i said,just a thought
Yep I remember someone mentioning this to me when I did it. If you break the extractor off which is actually quite easy to do you have to take the head off then as the metal in the tool is too hard to drill.
