Spark Plug Issues (Straight Six)

I was changing spark plugs today, and as I was pulling them out, I think I pulled part of the block off as well, or possibly a spacer, but none of the other ones had one, and I was wondering if you could buy a sleeve so the new plug could fit in. (Top is the one with extra sleeve)

Re: Spark Plug Issues (Straight Six)

Some one probly heli coiled it some time are there threads in the block still? Looking closer sorry your pics not very good looks more like nut sert.
They ruin treads and put an insert in. Nothing wrong with them if installed right>

Re: Spark Plug Issues (Straight Six)

I agree, it looks like a heli-coil to replace damaged threads in the head. A bit odd, because I've never had problems with the plugs in these heads.
