Specs At A Glance

Good To Know

Q: How many retainers do I need for a full valve job? A: The 1503 engine uses one retainer per valve, so count your valves to order the right quantity. Inspect all of them at once since they wear at a similar rate.

Q: Can I reuse my old retainers? A: Reusing worn retainers can cause valve spring pressure loss and poor engine performance. Replacing them during a valve service is good practice.

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