Hey all, been awhile since i posted anything around here, thankfully its because i havent needed to, shes been running great, well i went to pop in some new plugs this afternoon to find the 3rd plug in from the front, the threads are going, im afride next time i may not be able to get the plug to stay in properly, for now its secure and well, anyone have any tips on how i should proceed when the time comes, new head? used head? etc etc, i doubt its possible to fix threading there as the plugs are standard sizes.

you can try a thread cleaner as suggested..or get the head heeli-coiled..

you can buy kits but i wqould STRONGLY advise you to get it done by a pro..

basically they expand the hole and then cut it with a bigger thread..then screw in a insert that has the right thread for the plug in it...the TRICK is to get it straight and not to drop bits into the cylinder while doing it...

i have had it done on vehicles before...personnaly i have always taken the head off and taken it to have it done..but i believe it can be done on the vehicle...

if you take the head off its a great time to also decoke the block, fit a new gasket etc...

I think i will take your first suggestion there, and rather have someone else do that. if i were to do it all myself i would do all the relevant gaskets, but if the shop i have do it says they need to take the head off might as well also. Anyone in the Los Angeles/ Orange County area know of a shop that will do this cheeply, the occasional shop i use for things i cant do myself is to much, for an extra $10 and hour i could take it to the dealer.

when plugs foul up, it's always on the outside, right? there's a tool that will fit into the opening, expand to the good threads in the head, and clean the damaged threads up on the way out. either, buy 1 or look for a shop that has it. don't know how much it is, so that's your call. good luck, chuck.
