Helicoil, I've found the Snap On style inserts come out with the first spark plug change. |

One of my cylinders has a threaded insert. no problems with it since it had been done. but i have not been there when during spark plug changes so im not sure what would be better. |

Viking, I've used KD inserts a long time back, but even with the correct ( high temperature?) thread locking compound, they had a habit of coming out with the plug.  < http://www.mytoolstore.com/kd/kdengi11.html > After that, the local motor cycle shop would fit Timeserts, but only if the head was removed from the engine. < http://www.timesert.com/html/mtrcsert.html > Those were very good, however the bike shop closed down so I started using Helicoils and have never had a problem with one I've fitted. At Kelso, even though I wasn't connected with the 'on site' garage, they ran out of Helicoils and 'borrowed' more than a few of the supply of spark plug Helicoils I happened to be carrying with me. Paul, interesting that you should advise changing the head, since a time served engineer I know would fit helicoils in the heads of any engines he was building, as a matter of course. Not just the plug threads, but the M7 threads on both the oil feeds and inlet manifolds as well... ken. |
