Good To Know

Q: How many gaskets should I order? A: Check how many power valves your engine uses and order one gasket per valve. Replacing all of them at once avoids repeat teardowns.

Q: Should I replace this gasket every time the power valve is removed? A: Yes, a fresh gasket each time the valve is pulled gives the best seal. Reusing an old gasket risks leaks and poor valve operation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
