I'm wondering if the pistons on my 08 135 are forged as well?
I do know that visually, you can usually tell cast pistons by the raised numbers and casting seam lines, and usually forged pistons have stamped numbers, and they do look quite different on the undersides. I've built a few engines with forged pistons (coming from cast) so I know how to identify forged pistons by their appearances.
Pics would be great.
