rsweeney 40 Posted April 5, 2011 Report Share Posted April 5, 2011 well i spent £20 on this helicoil kit took one of the inserts and it is to big for the spark plug! which kit do i need for sure as its doing my head in . heres the kit i bought http://cgi.ebay.co.uk/Thread-Repair-Kit-M14-x1-25-Helicoil-Type-Spark-Plug_W0QQitemZ290547224751QQcategoryZ30917QQcmdZViewItemQQ_trksidZp5197.m7QQ_trkparmsZalgo%3DLVI%26itu%3DUCI%26otn%3D5%26po%3DLVI%26ps%3D63%26clkid%3D8248148326917344399 Link to post Share on other sites
Vw_owner 1 Posted April 5, 2011 Report Share Posted April 5, 2011 hi m8, small world!! im also from the rock! aka guernsey,just looked up my spark plugs for my vr6 and its a 14mm thread so in theory the kit you got should be fine, are you only thinking the inserts to big because its a slopy fit on the plug? if i remember correctly {its been a few years since i used heli coil} the insert will get slightly smaller when its skrewed into the metal,get a scarp peice of metal and drill a hole and basicaly test it out, it might be ok Link to post Share on other sites
rsweeney 40 Posted April 6, 2011 Author Report Share Posted April 6, 2011 ok cheers will try this out but the inserts dont look like they are going to fill the whole thread ? Link to post Share on other sites
Vw_owner 1 Posted April 6, 2011 Report Share Posted April 6, 2011 not sure exactly what you mean? but the thread length on my plug is 19mm aslong as the coil can bite enough thread so it can be done up tight without striping it should be fine, but like i said, to be on the safe side rather then drill into your motor, do it all on scrap metal first then tighten down the insert then put the plug in nice and tight and see if it holds if it does your sorted!!, when i used heli coil it was only for an m6 bolt and the coil threads didnt exatly match properly but it worked..good luck hope it goes well!
