ok where is the fuel pressure regulator? would i need a new one or is it a gasket gone or something simple? thanks for the reply.

hi i have a disco td5 2002 only had it a couple of days. It developed an oil leak at the rear of the engine on the drivers side now today it takes ages to start but runs fine once started. but still takes ages to start hot or cold. Any one have any experience of this thanks.

sounds like fuel. try overhauling the carb.
