I am hunting down a hot-idle problem. I've found many suggestions in past posts, and am currently following them.

As part of this, I am going to replace my PCV valve and my CHT sensor. No problem there, found them on PP. BUT, I can't find the copper washer OR the little gasket for the PCV.

Anyone got part numbers for these? Or are they easy-to-swap items that I can find in a local hardware store? I've also seen the posts for the 13mm DEEP socket that allows removal of the CHT, so I'm all over that.
