Frequently asked questions

What is the ERC1637 valve cotter?
The ERC1637 valve cotter, or split collet, locks the valve spring retainer to the valve stem on the Rover V8 petrol engine. It holds the valve spring under compression in the cylinder head and is sold individually.
How many valve cotters do I need for a Rover V8?
Valve cotters are typically fitted two per valve, so a full V8 head set usually needs 32 for all sixteen valves. They're sold individually here, so order the exact quantity for the number of valves you're working on.
Which Rover V8 engines use this cotter?
This cotter fits the 3.5L twin-carb and EFI, 3.9L EFI, and 4.0L and 4.6L EFI Rover V8 petrol engines. That covers the Defender, Series III Stage 1, Discovery 1 and 2, Range Rover Classic and P38. Confirm your engine before ordering.
Can valve cotters be reused?
Valve cotters can sometimes be reused if the grooves are unworn, but they're typically renewed during a head rebuild since they're cheap and critical to holding the valve. A worn collet can let a valve drop, so fresh ones are the safer choice.
