Replacing Valve Seals on Mazda MX-5

Model: Mazda Mx 5 MK 3, NC - Years 2005-2015

In this video tutorial, you will learn how to replace the valve seals on the cylinder head (without removing it) in a Mazda MX-5. First, open the bonnet. After removing the upper part of the cylinder head, you need to either build or purchase a puller that will safely extract the valve seal. This operation is not the easiest, so be careful not to damage other components like the valves. Then, refit the new seals, ensuring they are well lubricated before placing them in the valve seats.
