Did you pull the rest of the plugs out? Ill bet they are all hitting the pistons. If they aren't something bad wrong in that cylinder.

Yes i've pull aut all other plugs...Just this one made a mess on cil #6...all other look fine...black but fine.

That plug doesn't look broke from an impact to me.
It looks torched, melted.

Yeaa...the exoust was extreemly hot before that happend..

Did you do compression on all others to see how if, if anything, #6's 120psi is ?

No i just tested #6 all other plugs look fine..and when i test #6 it pumps 120 psi in a few sec does not take a lot of time

Do it, just for schits and giggles, and let us know. (See, you get to learn american terms while learning our engines )

Ok profesor SB...i'll do that and let you know but i know there will be no change the other 7 cil will have 180 psi for shore...i can hear the cil puff out compresion good...giggles mean laugh and schits i dont know

Pretty much the same as doing something “for the hell (heck) of it.”

Ok i'll do it for the hell
