Possible Turbo Trouble, anyone know a good patrol mechanic in perth!?

Gday everyone after buying a Patrol a few months back I've taken it for a run, and came home with an oil leek from my turbo, both the oil in and oil out seals were practically non existent (upon inspection no oil was found to be leaking into the air system), after having that fixed i took it out again, over Avon weekend in some very hilly terrain and found it to be sluggish as a granny on a zimmer frame. on my way home from the camp site, the engine reached its operating temp and then the engine light came on and it seemed to me that the turbo stopped working all together, it was then seriously sluggish, it would take for ever to get to 100km/h and im fairly concerned. once at 100km/h the engine seemed to slow down and then speed up buy about 5 km/h on the flat straight hwy (i was using the cruise control)

so can anyone give me an idea of what im looking at here, and if anyone can suggest a mechanic in perth that specialise in patrols or someone that is seriously good and reasonably priced.

ive also spoken to the mechanic of the guy who i bought the car off, he did allot of work on it, doing a replacement long motor, replacement fuel pump and fuel chip basically a brand new motor, and he had suggested to the guy that the turbo be replaced and the intercooler aswell, as the intercooler had a leak, im not sure if the turbo or intercooler have been replaced. but im starting to think probably not, just patched up and flogged off to me.

PLEASE HELP!!!

What year ,need all the info, First off I'd disconnect the Battery, Remove the engine cover and check all hoses to make sure they are tight,
You haven't mentioned if you have NADS fitted as it may well be going into limp mode from over boosting, is it billowing heaps of black smoke???
?????????????????????????????????????????????????? ?????????????????????????????????????????????????? ????????????????????????????????

Sorry mate its a 2003 gu Di, no NADS fitted yet as the money i keep allocating for it keeps getting spent on trying to figgure this turbo out. it doesnt seem to be billowing any smoke once in limp mode. the only smoke i see is a puf of grey smoke when i start the car.

ive just removed the engine cover and theres oil residue all over the front end of the intercooler, so it would seem that the intercooler has not been replaced, as the mechanic said it was leaking... and there doesnt seem to be any loose hoses

Cool next I'd be cleaning the MAF sensor. SCA sell maf cleaning spray
You might try fitting a catch can first to stop all the oil residue.
I'm of opinion you need to fit NADS asap to control boost and therefore EGTs.
Seems you can't hold boost, so a change over intercooler maybe in order

ok so i looked up how to check fault codes ect, and the last stored fault is 0707 Injection Pump injection timing control what does this mean?

i do know one thing... i know warranty will cover this issue! WEEEEEEEW!!!!!!

Royce,

Clear the codes, if you can, and see if the same one returns.

Sounds like the car has gone into limp mode, as I have had that on mine, and it would cruise at 100, but if you hit a hill, it would die in the butt.

Mine was nearly good as gold once I turned the key off and restarted. Now I've fixed my problem totally, it is all back to normal, and is as good as gold.

It could be a whole host of things, but there are a lot of faults and reports that I have read that say it could be one of the following :

A leaking Intercooler will result in power loss.
The Turbo Actuator is stuck
The MAF
Split Hose or hose come off from the turbo to the intercooler.

Check the basics first, before you jump to any conclusions....

Mic

Cheers Mic, will look into all of the above, i do know that the intercooler is leaking for sure and i will be replacing that as soon as i have exhausted all other avenues, although it did not start doing it until i had the seal replaced in my turbo. since then its done it 3 times, and im too affraid to drive it anywhere else but the mechanic.

how did you fix your problem mic? mine sounds almost exactly the same, as soon as i turn the car off and it cools down i turn it back on and its fine until it gets to optimum temp and then the engine light comes on, and it goes into limp mode.
