Rocker Cover Sealing Washer seals a rocker cover retaining bolt on the 200Tdi 2.5L turbo diesel engine.

The washer fits under the rocker (valve) cover fixing bolt where it passes through the cover, sealing the bolt hole against oil escaping from the valve gear. Renew it whenever the rocker cover is removed, to restore an oil-tight joint at the fixing.

Frequently asked questions

What is the ERR663 sealing washer used for?

The ERR663 sealing washer seals a rocker cover retaining bolt on the 200Tdi 2.5L turbo diesel engine. It fits under the bolt where it passes through the rocker (valve) cover, stopping oil escaping at the bolt hole. It fits Defender, Discovery 1 and Range Rover Classic.

How do I confirm this washer fits my 200Tdi?

It fits 200Tdi 2.5L turbo diesel engines: Defender, Discovery 1 up to VIN LA081991, and Range Rover Classic 1992-1994 from VIN JA610294. Check your VIN against these breaks to confirm, as the 200Tdi sealing arrangement changed across the range.

How many sealing washers do I need?

This washer is sold individually. The 200Tdi rocker cover is held by several fixing bolts that each typically take a sealing washer, so count the bolts on your cover and order one washer for each to reseal it fully.

Should the sealing washer be replaced when removing the rocker cover?

Yes, renew the sealing washer whenever the rocker cover is removed. The old washer takes a set once compressed, so reusing it on the 200Tdi typically lets oil weep past the fixing bolt. Fit fresh washers to restore an oil-tight joint.
