Video: Replacing Leaky Valve Cover Gaskets On A GEMS Engine 1997 Defender 90
What's happened is the gasket has become heated and compressed.
Basically taking the sealing properties away from the valve cover and the bolts, on your GEMS engine Discovery 1, Defender 90, Classic, and '96 to early '99 P38 Range Rover.
This is why they leak.
And over a period of time you will do these on a regular basis on these just by design every 3 or 4 years.
Watch Doug, our Land Rover Master Technician, as he takes you step-by-step in gaining access to and replacement of the valve cover gaskets for a 1997 Defender 90 with a 4.0 liter GEMS engine.
You will need two gaskets to perform this service.
Great products and excellent customer service. I always know what I'm getting and when to expect it and can trust it is going to be top quality.

Best selection of the latest Rover merchandise - better than even most dealers…MUCH better than the Land Rover US site. Super quick to pull orders and ship out.
