Can i "mix" spark plugs? PROBLEM.

how will i know though.....?

 

eh? how? what? eh?

 

if the e-bay thing paul linked does the job that's good enough for me..... i just wonder how i know what thread is already "cut" into the head now?

 

just as easy to leave it and get that e-bay thing if the thread is the same that's in the head now?

 

You need one of these to measure the thread!!

cheers paul i guess i've a bit to do.... to be honest i'm erring on leaving it alone as i'm fairly convinced the engine is gonna have to be stripped in a year or two, one of the studs in the head to heat exchanger is stripped and blowing so the little jobs are mounting up, bar having a used plug in it as long as it stays tight it won't hurt as is will it?

 

Nah, you'll be fine for the time being
