Hey ya'all. So I was trying to figure out why my left cylinder was not firing and took out the plugs for inspection. The left plug is always kinda a pain to put in or take out. The right one works just like the book says. I can hand tighten it till it is almost all the way in then give it a 1/8 turn with a wrench. The left one however was always difficult. Well you can probably guess what happened next. When putting the spark plug back in i overtightened it and felt it strip. Now it doesn't make a tight seal and I can feel the air being pushed out of the cylinder around the spark plug. WTF do i do now? I'm assuming I will have to tap the hole out. But the logistics of it are beyond me. Will I have to take the cylinder covers off? To what size should I tap it? Are there heli coils that I should use instead?
