There is - or there is supposed to be a throttle plate in the transit engine. A previous owner has seen fit to remove it and disconect the exhaust recirculation valve. So there should be at some stage a vacuum in the manifold.
On a slightly difrent track - has anyone ever tried fitting a second injector in the head of a diesel, to inject water directly and do away with the cooling jacket?
I thought of using a thermostat to decide which injector to fire - either fuel or water depending on temperature. Cooling the engine internaly.
