Anyone ever suffer from stuck spark plugs in there Vtec Head? I know they are not over tightened but maybe carbon build up??? But the Two Center Plugs will not move at all. WD40? Anything else work to solve this problem? I am applyin heavy torq. but I don't want to break the plugs.

you're right, you SHOULDN'T be able to break them...but you can, if you're not careful.

 

what brand of plugs are those??

 

How did those plugs get worked out of the head after they broke? did you try and use some thread lubricant? I have anti seize on my plug threads and it still stuck

when you first put them in, did you torque them right (not over tighten)???


By the way, anyone know how much you should torque spark plugs?

 

Those are ND's.

 

How about puttin on some antiseize.

 

Those were from a JDM engine. That one was stuck on there because the hole was filled with water. Who knows if they used antiseize or how much they torqued it down..

Anyway, It had to go down to the machine shop to get it out.

 

I just make sure there hand tight.

 

it usually says on the box i think. i do like 15 ft/lbs.

 

13 lb/ft. per Helms.
