I'm performing a valve adjustment on the 5 cylinder turbocharged diesel engine in my Mercedes-Benz Universal station wagon that runs on biodiesel.
I used a ballpoint pen, which was difficult to get to lay down on the paper. I colored with Prismacolor pencils, but found it difficult to get large areas of color to blend smoothly, and I ran out of the white pencil.
I bought a new Faber-Castell pen set and hope to get better with blending large areas of color.
