You're welcome to pop round and take a look Ben or see for yourself next weekend if I get it back on the road before then. Towed back by the AA today, not sure what the problem is.

DCheers Chris, didn't even know the fuel tank had one, so thats one I've missed too. Where does the breather end?

Range Rover Blues:
Up inside the rear O/S wing somewhere.

DiscoDan:
Hi all.

The timing cover does have a wading plug but if the engine is hot & you drive through water the warm air in the timing cover can contract and this can draw water through the seals, hence the reason some people fit breathers aswell as the wading plug.

It is the problem of this air contracting when its surrounding casing is suddenly immersed in cold water that makes an extended breather necessary. Therefore the fuel tank breather isn't usually mentioned because the tank isn't at a higher temp than its surroundings. The breather allows air in as the fuel level drops. It could be argued that water could enter the tank breather through simple immersion and this is something I haven't thought of before.  :oops:
