• Q: Should servicing the intake valve, valve seats, and valve guides be left to a professional on 1991 Mazda 626?

  A: A valve job, which includes servicing of valves, valve seats, and valve guides, is a complicated task that should be done by professionals since special tools and equipment are needed.
