What's this called? No, not the hose, the filter. It came off of the passenger side head cover, and vented from the air cleaner through the hose. I have asked over at the 67-72 Chevy Forums, but no one told me what it actually is called.
Now this part, they knew what it was. No, not the spark plug, the other piece. It is a non fouler. If a spark plug is getting ruined, you could screw the non fouler into the block and then install the spark plug. Now I know.
When it came out, attached to the spark plug, I was wondering if I was in big trouble. Had I really screwed up and removed something that was not supposed to come out of the block? The plug and non fouler were so rusted together, that I thought maybe part of the plug had broken off in the cylinder.
Glad that is not the case.
I tried to find some cheap spark plugs last night, at Wal-Mart, but their cross reference materials only went back to 1973 on the computer, and 1980 in the printed book. And since they only had Autolite spark plugs, I could not tell which to use. So, no plugs installed. Maybe this weekend.
