Frequently asked questions

What does the rocker shaft cap plug do?

The rocker shaft cap plug seals the open end of the rocker shaft, keeping pressurised engine oil inside the rocker gear circuit. Without it, oil escapes at the shaft end and the valvetrain loses feed. It sits under the rocker cover on the four-cylinder cylinder head.

Where is the rocker shaft cap plug located?

The rocker shaft cap plug fits into the end of the rocker shaft, inside the rocker cover on top of the cylinder head. You'll reach it once the rocker cover is removed. It's a small press-fit plug that's easy to overlook during a top-end refresh.

Which Land Rover engines does this cap plug fit?

The rocker shaft cap plug fits Defender 1987-2006 with the 2.25L and 2.5L four-cylinder petrol and diesel engines. It's a common item to renew during a rocker shaft or cylinder head overhaul. Confirm your engine type before ordering.
