Mark, you have lost me a little.
The waste
gate on the turbo does play up some times.
Mine had a bit of wear and wouldn't go past 9 psi.
But isn't there another safety blow off valve on the back end of the manifold?
When I turned my boost up on the 2.8 to 15 psi, the manifold one kept blowing off like the ricers do. Big woosh at each gear change. Worked out the 2.5 manifold valve was set to 20 psi, while the 2.8 manifold one was set at 16 psi. So put a 2.5 one in my pajero.
Reckon nissan should have done the same with the 3litre patrol.
A safety valve on the manifold might have saved a few engines.
It is a bit of a pain when it does go, have to wait a second or two to reseat, before you get boost back. Not good when you are on the wrong side of the white line passing a semi like a friend of
mine was in his 2.5 pajero, but that 2.5 was faster than my stock 2.8.
