hey guys well i finnaly got my patrol its a 2001 3.0ltr the guy upgraded the turbo but the car was running rough. So i got it at a good price but have since fitted a boost gauge and have found out that its not boosting past 10psi and its blowing black smoke under acceleration no idea why i have looked at heaps of threads on here and tryed a few things but cant seam to put my finger on it though maybe injector pump ???
I'd be first up getting a good tune up..
Possible over fueling I'd say. Maybe previous owner did a DIY tune..

Is that upgraded the Turbo, or replaced the Turbo with a new one?
there is no upgrade of the turbo on a zd30 you either replace the old one or you change the turbo froma vnt to a standard turbo if it's a standard spool up type it'll need tuned if it's a vnt turbo you have a bad boost leak prob a split hose or leaky intercooler.
Sounds like a leak in the intercooler or the IC hoses have come off. Check where the hose comes out of the turbo. It is a common place to leak and is hard to get at.
Yep as stated above definatley sounds like a leaking intercooler or blown hose ect
sounds as if thats it and clean the maf with m.a.f cleaner from repco or supercheapQuote:

If you're tight like me u can pull the OEM intercooler apart & use gasket adhesive to re-seal it. Works a treat.
Check ya air cleaner, fuel filter etc
A good engine service would be a good idea.
cheers guys it is a new turbo dont know exactly if its a standard or a vnt it says its a garrett m24 so ????????? and yeas i can hear a noise sounds like a leak its coming from behind the engine possable egr pipe ???? what do i clean the inter cooler out with ?????
Really need to NADS your 4x4 asap
fit boost and EGT guages, block EGR.
fit manual boost controller and needle valve.
remove clean and check IC for leaks
As suggested clean MAF check all vacuum and turbo hoses
replace any split or perished ones
Do you know if Chip is fitted????
Degreaser petrol kerosene just make sure its dry befor you install it
ok first of all im still new so whats NADS ???Quote:

how do you test the ic for leaks
and isnt the boost contoller and needle valve the same
and no it does not have a chip fitted
cheers Anthony
Start the car and give it a bit of gas and feel around the intercooler, you'll soon find where the leak is.
If its a big leak you will notice you'll prob b droping boost on your gauge aswel.
As for the hoses mate have a good lock around and you'll soon spot if something doesnt look right and you will also hear a hissing noise whisle driving
By NADDING your GU you control the boost, best thing ever.
you'll never overboost ,the needle valve will control spool up rate
different to Dawes valve. Pop Mudski a PM for pricing on all the bits
required, including EGR block. Then once guages fitted you'll see whats happening
instead of guessing, Plenty written on this subject, search Chaz yellowfoot [guru]
Great peace of mind for any Direct injection zd30
Remove all the IC hoses and check for leaks. Being over 10 years old no doubt the IC hoses will be worse for wear.Quote:

If its the EGR, usually, it will give off a squeal when the engine warms up. Like I said, usually. Some have mistaken the EGR leaking for a belt squeal.
Cheers mudski yeah its squeeling coming from exhaust manifold no 4 cay i just put the car in today the get compression test done as my mech has a gu4 and he thinks mine is only running on 3 i hope notQuote:

I got my money on a warped EGR pipe if its squealing. Actually, which side of the engine?Quote:

Ok got car back compression reads as this. 1) 400 (2)400 (3)100 (4)50
They think its just valve adjustment i took it to hi tech diesel
So yeah now i dont know what to do
Don't want to be the bringer of bad news but no compression on 3 and 4 doesn't look good for the pistons, especially since it is an early 3 litre ......

Yeah i know im hoping its just a head as its using a lil coolant to but yeah i dont know as the engine runs fine at 110 on a flat bit of rdif it was only on 2 it would struggle wouldnt it
That seems to be good news for you as if you have holes in the pistons i don't think that 110 is a possibilityQuote:

That doesn't look good. Lets hope its the head.Quote:

If motor was U/S it would be shaking its head off, may well be valve
adjustment, hope for you it is.
the motor shakes a lil bit but only on idle so yeah hope it is just the valves
Too late for the NAD's TD I reckon. Once the damage is done, its done. Got my fingers crossed for ya mate.
Mine ran fine when it was busted. Ended up needing a complete rebuild. Hope it works out for you mate.

Only way i knew i had problems was that the coolant was getting pressurised and coming out through the hole in the over flow bottle.

Wasnt blowing smoke either. I never noticed any and nobody ever commented on it anyway.

ok so i pulled it down today to find that my intake bolts were all loose and the turbo bolts done them all up and it ran so much better. Then i undone the exhaust from the dump pipe and found out that my exhaust is full of soot hence the smoke. I then put all back together and it ran like new but keept hitting 18psi boost only drove 2km went home and as i was comming up my street it suddenly lost all power and is really non responsive and blows heaps of smoke ??????
has it finally given up and called it quits i hope not ?????
If its spiking up to 18 it could be quickly going into limp mode. Does it go ok once you release your foot off the pedal and go again?
no it doesnt and it struggles to get to 2k rpm but then its fine up to 4 When i first start it every time i cant rev the engine the pedal just wont do anything for the forst 3 mins of start up it just idles could it b a ecu fault or even a fuel pump ?????
Throttle position sensor it sounds like to me. Had any water or muddy feet in the cab. How is your naff sensor boost and egt temps
Dirty - are you near Mt Barker in SA?
Maybe one of our esteemed colleages near you may be able to help. If you can get two identical cars together, you may be able to check for any differences in the setup for the Turbo......it might have been adjusted wrong
Is the cylinder compression tests still all over the place?
Mic
Could be fuel pump. When mine went the car goes into a limp mode. I could just drive it but engine wouldnt rev up.

Yes it may be your fuel pump . I would reduce your boost say 13 - 15 tops , fit egr blanking plate and replace your MAF . For less than $200 it eliminates a couple of things . JMO .
thanks guys no water in the cab i just went out to start the car and it started and then it stalled after about 30 sec i tryed to restart the car only to have it stall after about 5 sec then after the 3rd attemp to start the car it wont run longer than about 2 sec without it stalling im leaning towards fuelpump
