i have my 3 number spark plug thread well worn. it is still servicable though.
i am going to chase the thread with a grease covered tap to try to improve things. Question is, Can i fit a thread insert without taking the head off and all the filings getting into the cylinder ?

I've chased spark plug threads & regretted it.
Just made the plug really 'loose'.
My suggestion would be to live with it, or have the head off & have the job done properly.

Like Gb says live with it until absolutely needed or take the head off and have it done properly.

When I was at school, I chased a few girls.
But never a spark plug thread??

There is a new tool on the market that you lower through the spark plug hole it then expands and you thread from the combustion chamber outwards,sealy tools

Hi Andy, Did you give it a try ?.One of the plug threads in mine has some damaged threads

I can't see how this works.
I could see it being useful to clean up a cross threaded plug hole but chasing the thread will removed material which won't make the plug a better fit.

Do it right & whip the head off.
I used these
http://www.timesert.com/AFTER I tried the grease way.
I will try & post a pic of my valve once it chewed up a small fragment that the grease did not catch. (Not a pretty sight)

Andy - I have a spark plug thread chaser tool very similar to that mate. ( same thing but a different make)
I have never used it cos I've not had cause to but if you wanted to try it instead of buying one you are welcome to borrow it.
I am pretty sure I also have some spark plug helicoils too if you need them
I am just off junction 36 if that is of use to ya ?.
