They definitely walnut blasted the intake valves. you can see the bits of walnuts in the pics on the edges of the valves and there are walnut bits in little places in my engine bay they didn't clean out.

I'm guessing it's because its a discounted rate they spend as little time as possible on the car so they did the minimum.
