Car Forum / Peugeot Cars / August 2007Sheared 406 plug !
you could guess the language i was shouting ! On Hols next saturday, thought i will change the plugs on the 406 2L '99. Damn & ^&*^% Sheared one plug at the edge of the head undoing the thing, down a hole ! (&(*&&^ As far as I can see, there is no way to get at it & I dont want broken bits of ceramic in the cylinder. Looks like a head off job. Dammit. Am I right ? Can you still get the plug socket on to any of the plug?(nut)if you can soak it with wd40 over night and by the evening you should be able to remove it(do it up a little just to crack the thread) Sheared at start of threads. I have the bit down to nut in my hands ! > Can you still get the plug socket on to any of the plug?(nut)if you can > soak it with wd40 over night and by the evening you should be able to > remove it(do it up a little just to crack the thread) can you get a punch in there and tap it round,or force somthing into the plug whats left of it and try and turn it out. > can you get a punch in there and tap it round,or force somthing into > the plug whats left of it and try and turn it out. On a 406? I doubt if I could get a pair of snipe nose pliers on the plugs in mine (2l 16V)!

It sounds like a nightmare scenario, if it was so tight it sheared off at the threads, it's unlikely to want to tap out and as previously stated they aren't the worlds most accessible. Any kind of stud extractor inside runs the risk of ceramic & ctr electrode into the combustion chamber. The only good side I can see is it's not my car(!) The only possibility that springs to mind is freezing the remains of the plug itself, which may shrink it enough get it to turn. (TV shop freezer cans will theoreticaly get it down to -40DegC if liquid Nitrogen isn't available) Djimbo.

People on here seem to think it best to do it at the same time as the belt. SignatureKeith Willcocks (If you can't laugh at life, it ain't worth living!) More bloody money hahahaha just because of a spark plug.. |
