Model: (Various brands) Various
Part: Valve

Video tutorial

Today, you will see the main steps to disassemble and replace the valve seals of a cylinder head. This operation is not very simple and requires a lot of patience and attention (and a minimum of experience).

First, we need to extract the valves from the cylinder head: to do this, use a special extractor that will help you leverage and remove them. At this point, you can remove the valve seals with pliers, being careful not to damage the valve seats.

Once replaced, reassemble everything using the reverse procedure, lubricating all components first.
