Hi guys, I've really done it this time
I was changing my crappy NGK plugs back over to the better Golden Lodge Jobbies (now that the car is running properly and I know it wasn't the plugs).....well.......
.........one of the NGK plugs decided to come apart while still screwed into the head .
Basically the middle bit came out leaving the threaded bit in the head. I managed to "save" the day by covering the centre bit with super glue and pushing it back into the part in the head. The car starts and ticks over fine, but I don't think the glue will hold the plug together for long once it gets really hot and under pressure.
How can I remove the stuck bit of the plug ??? Will I need to take the head off and risk breaking valves (I have previous for that ) when I put it together again ????
Will the glue hold ????
Any tips at all for getting the bit out the head ??????
had the same problem Marlon a few weeks ago. new ngk small spark rung and it wasnt even tight nor wrong threaded in the block. got a set of these reverse thread jobs in the motor factors for 10 euro. a cheap brand called SPUR. see their stuff in diy tool shops and DIY stores. Irony was the old spark was still perfect afer 72K miles anyway so back in it went to be there forever. you will need a small socket set to use the extractor as the plugs are down narrow holes.
Thanks guys I'm gonna check out these "easy out" and other doo dahs
My car is officially dead just now. Got half a mile of gentle driving before it blew the plug apart. Fixed it and managed to get nearly home before it blew apart again. My car is now at the bottom of the drive.
Thankfully I have 3 days Tax left on Shugs old 33 !!!!
One thing to do before you try to take it out is run the engine up to temperature then try and remove it....................the heat helps swell everything that little bit and can make the removel of the thread a bit easier
Other than that will be a head off job ................unless you wanna try drilling it and re tapping it which is possible but very dodgy as the swarf can get into the bore`s even using a hoover aimed at the drill bit to suck all the swarf up
think about it. if you where drilling it the swarf comes upwards. the reverse thread on the easy out will be pushing what little swarf there is upwards, it's got threads not drilling edge's, so little swarf will be produced.
As you turn it anticlockwise it'll screw down until it tightens then the force will be on the plug to unscrew.
