the whole idea of a dump valve is to release pressure in the inlet manifold when throttle is closed which otherwise would cause turbo impellor to slow down pretty rapid. if you aint got a turbo then you aint got no pressure, you only got vacuum. the dump valve aint there just to make heads turn, it actually serves a purpose. saab turbos have them fitted as standard and they dont even make a noise.

what is it with escorts, dump valves and turbos. Please....they look sh't!

sounds like an escort turbo with a blown engine has had a 1.8 engine dumped in it. trust me my dear boy - if it hasn't got a turbo, it doesn't need a dump valve.
