Moved as this is clearly not a guide...

My advice would be to remove the dump valve from your diesel. Other than that... there must be a leak somewhere.

I'm with Curt tbh, dump valves on diesels just dont sound right. Best bet is to just do away with it. If you're still low on boost after that, check the usual suspects for leaks.

a dumpvalve on a diesel IS a leak

Totally agree waste of time on a derv n sound shit as out of time get a big blower instead

Agree with all the above, I had one and removed it a week later as it just did't sound right.But to answer your question, check the gasket on the tmic if you removed it, check all jubilees, etc.....

And you ask why you have a leak?

I had one had to switch it off if wanted to boost over 22psi if its bot holding 16 then its not a twin piston one for a start
Or its f*cked

errr....you have to created the vacuum from somewhere to make the dumpvalve work....tells you something about why you dont and shouldnt have a dumpvalve on a derv
