If you make it with a crushable washer (a)it costs a penny more (cant have that !) (b)i think it would carbon up all the way up and seize in even more But i do think they should make them accessible like spark plugs and change them every two years or so. I always grease the threads with copper slip and they come out like a dream next time
I was thinking more if the thread was in the combustion end of the cylinder head like a spark plug, rather than being threaded at the outer part of the cylinder head and there fore no carbon build up. It's always a bonus when they have been anti seized, you are right, they won't put extra cost onto an engine just to help mechanics
I had thought about doing that, then figured out that the other way will do the same job and save the tool. Incase the tool will work ok on another car. Cheers Matt
