Has anyone got a recommendation for a turbo repairer in the southeast Queensland area (preferably somewhere around Brisbane southside, Logan, northern Gold Coast)?
Car is a 2002 GU, ZD30Di
Pretty sure it's the water cooled type turbo, hense would prefer rebuild over a new non water cooled.
I'm guessing it's done an oil seal. School run this morning seemed to start out as normal, slight noise that I thought was one of the boys imitating the increasing revs of the engine.
Then noticed boost was low and a little white smoke (strong burnt oil smell).
Was still driving ok and not making dangerous noises so pushed through gently to get the boys to school (it's a short trip and I was in a 'I don't give a stuff if you blow up' mood).
By the time we got to school there was a billowing white smoke screen behind us. Still sounded to be running fine though.
Engine didn't run-on like I've read others mention. Shut down as normal.
No visible external leaks.
I guess I'll be learning how to remove/replace a turbo next! ☹😫🤬
To be fair, as far as I know it could be the original turbo, and the car is approaching 300,000klm.
Generally a new Centre Housing & Rotating Assembly is cheaper than overhaul and balance of an existing item. You just add your own turbine and compressor housings to the new CHRA. Is the turbo original? Most aftermarket turbos have water cooling facilities but they are often not used on diesel engines.

Water cooling on the ZD30 turbo finished around mid 2002, if you do have it I would recommend retaining it, dropping water cooling was just a Nissan cost saving exercise like many other things around that time. If you look at the passenger side front of the head you should see a banjo bolt through an 8mm water line if you have water cooling, it also bolts to the back of the turbo against the block whereas the oil lines bolt to bottom. If it is water cooled it is a pain in the arse to get off, I've done it several times while playing. There was a young guy here on the sunny coast that rebuilt turbos, I'll have a look and see if he's still around and doing it.
Yeah fair point JFF45. I just assumed turbo from the burning smoke and turbo noise.
What are some other possibilities? Holed piston?
I'm working midnight's at the moment so can't get too deep into things during the day or I don't get enough sleep.
And she's out in the open at the moment so the rain is stopping me from having a decent look at things. I've got almost all Friday free and almost all weekend so I'll put her in the shed Friday and do a bit of probing before any major surgery.
I'm no professional but I like to do all my own work where I can. Had too many disappointing results from "qualified mechanics".
Had a chance this morning so thought I'd do a quick look inside the hose from the turbo to the intercooler, then the intercooler to the throttle body, and found heaps of oil! My catch can isn't 100% but it's better than that!
Intercooler inlet and throttle body inlet.
Puddle of oil inside hose from intercooler outlet to throttle body.
That grabbed my interest so decided to spend a bit more time pulling the bend off the intake side of the turbo that Geeyoutoo mentioned. No noticeable endfloat on the compwheel (by hand) but HEAPS of sideways movement. I took a video but it's too big to add.
Are there contact marks on the housing throat that would indicate the the compwheel has been rubbing, you may also see contact marks on the compwheel, can you feel it touch the housing when you rattle it side to side?
Maybe clean it up and drive for a week and pull the front off again and check for oil. You can also temporarily run the breather hose into a milk bottle or such for the same period just to rule out catch can/breather, don't forget to plug the hole the breather connects to.
I got a screen grab from the video, definitely looks like rubbing to me, and I'm pretty sure the vanes aren't spose to have that curve to the back half but this is my first dance with a turbo so I could be wrong.
You can hear it tapping in the video when moving it from side/side and up/down. Will keep trying to get the video up.
I pulled the breather hose off that goes from the catch can to the intake hose when I was removing the front bend off the turbo and no oil came out of it. My catch can hose is clear and does have some staining but looks the same as it has in a long time. And there is no oil in the little clear pipe on the side of the catch can which means it's close to empty. Where as this was the pool of oil in the hose from the intercooler to throttle body.
Btw, when I checked the oil level after the tow home it was off the bottom of the dip stick (it's the shorter dipstick) and took about 1.5-2L of oil to get it up to about 3/4 healthy range on the dip stick.
Going to start it tomorrow to move it into the shed so I'll get a pic of the smoke screen. 😉
OMG that is screwed, the still photograph didn't give that impression, one of the worst I've seen, luckily all that oil in the system will have trapped the particles of the compwheel that got sucked into the intercooler, do not drive it. Remove IC and all pipework back to and including ThrottleBody and clean.
