Hi fellow patrol owners... went to jump in my bus this arvo..went fora drive and it seems like it won't boost past 2000 rpms...goes up to and 5-7psi then will drop off to nothing.. After 2000rpm it's got no balls... Is this what they call limp mode? Zd30..
hopefully someone with a zd30 can help mate but it sounds like a leak and not holding pressure in my opinion. Check every connection from turbo to inlet manifold.Originally Posted by mullet_hunter
See if you can see any carbon deposit on any hose seals too?
Ye if feels like it's leaking boost.. Like when a hose comes off the intercooler.. But it's not blowing any black smoke and hoses look alright... Will need to have a better look over the weekend..
Whats it like prior 2000rpm? Cleaned the maf lately. Could be a boost leak. Condition of the intercooler? Is it oem or aftermarket? Any oil leaking from the intercooler?

Also what about the fuel filter. Last changed? When you get limp mode if you let off the go pedal and back on again it goes away.
Ye it seems if u let off the gas pedal then it will boost to arnd 2000rpm.. then nothing over that... is this what they mean by limp mode.. im just a bit dumb founded how its just happened nw.. been running 27psi befor with no dramas no i cnt get it to boost much over 7 to 10psi...
Mafs clean.. new fuel filter when i done injector pump few weeks back.. will have to have a better look into the weeknd...
Split hose for sure mate.

The only good thing about an 80 series is..... the front end?? Wrong!!, the Engine?? Wrong!! the Full Time 4WD system?? Wrong!! Its the NissanPatrol.com.au stubby holder fitted over the transfer lever.
WARNING: Towballs used for recoveries can, and do kill people and damage property.
Ye it drives and feels like the same as if it blows the intercooler hose off but no black smoke.. and hoses and clamps look tight n all in place...
With MR possible hose split or from running big boost split the IC open a bit more.
You can remove the IC and check in water with a bike pump, make sure its dry before you replace
it a hair dryer will help.
At Mudski MH is running a HPD Maf housing, you mentioned a
while back they should eliminate all over boost probs?
