My 2000 V-10 blew a sparkplug out of the hole yesterday, and the threads are toast now. I now have to replace the head on that side. Does anyone know what causes this to happen?
Is this a real problem with the V-10?
X-mas is around the corner and it is real cold up here in northern Alberta, so I want to make sure that this kind of problem does not keep happening at the worst possible times!
I remember someone mentioning these on here before. They have sparkplug repair kits at the sparkplug link at the bottom. Welcome to the site, sorry it has to be under these circumstances! http://www.timesert.com/
I wonder if that sparkplug re-thread idea will work or not?
I checked out the site you had suggested "Timesert", and the idea seems like it will work, but with the pressure our V-10's put out; will it hold the plug in place? and how long?
If this works, it will save me close to $2,600 worth of parts and labor.
We wouldn't suggest it if it didn't work....It will 2x stronger than original. It will be only one that will never blow out.
Call them I think they have a kit for the SD's...

Oh and V10's don't put any more pressure on the plug than most any other engine...
Had a plug blow on a marine engine several years back and was equally puzzled as to why it would happen. After talking with tech schools, story goes that if the plugs are not torqued to the right spec, ie. loose, they are not able to transmit heat properly to the heat sink of the block that they're supposed to have been firmly mated to for not only the strength of the bond of the screwed down plug, but as well, for the effective heat transfer that can only be accomplished when there is intimate contact between the plug & the block. Have used heli-coil thread kits several times in both cast iron & aluminum heads on boat motors and never a return problem - save your $2,500 and relax!
The trick is to not let any shavings get into the cylinder from the tapping operation.
A trick we used to use is to bring the piston up to top dead center, then fill the cylinder with shaving cream. Then vacuum it out with a shop vac with a long skinny atttachment.
And put grease on the tap.
