Hissing noise from rear of engine on cosworth

Hi all, My cosworth has been playing up for a a few days. It's very lumpy when first started and the idle is uneven. I had a look under the bonnet with the engine running and there's a loud hissing noise. It sounds to me like it's coming from the rear of the engine. Can any of you give me any pointers as to how to find the leak? are there any common culprits? You're help would be greatly appriciated Matthew
