Occasional noise
My truck (the '96) has started to make a strange hissing noise occasionally when cold, and throttle is eased. it sounds like a tire deflating, but comes from the rear of the engine, I suspect that it is something to do with the turbo. It does not do this when hot. Any ideas?

Could it be that back pressure valve thingie ?? or dont the older models have them ...... I'm not up to speed on the psd, just the fact that they run like a raped ape.
