engine flush for a 2003 mazda 6

hi everyone,
i have a 2003 mazda6i with 150,000 miles, would an engine flush be a good idea? also, can any one tell me how to get to the PCV valve? thanks in anticipation to your answers.

According to my repair manual, you have to remove the intake manifold to get to the PCV.

An engine flush couldn't hurt.

Do you need a transmission flush for a 98 mazda 626 if it jerks when you switch gears?
