I recently had my ZD30 engine rebuilt after blowing a piston at 107,000Klm.For warranty purposes i had to put a new turbo on as well as fuel pump& injectors. I only did 33Klms & the turbo blew (Warranty refused) new turbo fitted again. This time i got a bit over 800 Klms & it blew again.
These turbos over boost & wreck the engine or themselves.
Meanwhile a lot of research on the net & talking to a lot of Turbo specialists i found a place called TurboGlide at Russell Vale near Wollongong. This guy is really switched on about anything to do with turbo diesel engines. He sugested i have a conversion that he has designed done to my vehicle. This changes the original turbo over to a T25 turbo which has been around for about 20 years, it is repairable not a throw away like the original. The T25 has a wastegate so it can`t over-boost.
He then tests the vehicle on the dyno to check everything out.
My ZD30 was running lean at low revs so he put a module (chip) in it as well.
I came up Mt Uesley in top gear & could have excellerated but for the speed limit.
If you want to contact him Email [email protected] or go to his web site
www.turboglide.com.au.
Hope this helps all you ZD30owners who are disillusioned with this engine. Baldy65

Hi baldy & welcome to the forum.

Unfortunatly, the ZD turbo can overboost & can also be adjusted to stop this from happening at no cost, have a look at the ZD 30 reference document by Aksniss and co.
http://www.patrol4x4.com/forum/niss...ference-document-zd30-owners-look-here-31418/

Page 61-61
It will explain the SIMPLE adjustment to stop you vehicle from overboosting. It will also highlight many other issues & remidies that you may get.

if your chewing through turbo's i would get the engine oil tested. you may have diesel contamination. one common way that happens is leaking seals the the spill/injector return connections on the injectors.

Yep, diesel in oil for sure.

The original turbos are NOT throw away either.

Mine is deffinantly a throw away job. 1.6mm of play and very rounded blades. lol.
Less than a Km with not enough oil flow will faaaaark it for good.
