loosing boost cant work out where

[markstevo]

Hi all I have a 2003 nissan patrol zd30 full Nads bigger intercooler oil catch ect ect. Driving car yesterday there seems to be less power. I have looked at my boost gauge and can see it doesn't hold boost and immediately drops down to 0 it does still boost but not as high so not thinking turbo I have put new clamps on pipes and checked hoses cant see anything letting pressure out or cracks/splits what would you say do next? could it be the turbo anyone had similar issues and have a starting point.

All good that you found it, was going to mention soapy solution.

Nice find mate. A nice and cheap thing to fix as well.
