I walnut blasted the valves today. At 110k they weren’t as bad as I thought they would be, especially considering that I used to run 87 octane when I used my car for door dash. I had an oil catch can from when I bought it at 42k until around 85k.

Also walnuts got all over everything lol. If I do it again I would definitely try to make an adapter like this guy . . .

Here’s the media blaster I used

I got the fine walnut shells from harbor freight as well.
Unfortunately, the walnut blasting didn’t fix my misfiring issue.
