Mudski GU Build Thread

[jay see]

Sorry mate can only suggest the way it comes off is the way it goes on. I know not much help. Have a search around the Goggle machine, might find some tips.

Going to replace it or going different brand/size?

Is it a ball bearing or bush turbo? Bush will have a little play as standard.

I didn’t put it in so....

Not sure what to do here. See if I can repair it first. I don’t like the idea of spending big $$ on a new turbo. If I did though. I will go a smaller turbo I think. And something that can just be bolted in replace of what’s there. I cannot be arsed mucking around.

Definitely not burning oil somewhere else mate? I would have thought the oil would collect quite significantly in the intercooler ect if it was using a noticeable amount of oil. As in, I would expect oil to be running out, not just residual build up. You're talking a couple of litres missing over a service period aren't you? Should be pooling in the pipes everywhere. If it was being pushed past the exhaust side then you should be noticing it burning/blue smoke.

Tried running it with the intercooler side hose off the turbo to see how much oil is being spat out? Again, I'd expect it to be significant if this is your issue. The one I recently swapped off the patrol had quite a bit of play and was quite oily but I never noticed it 'using' oil.

Not saying your wrong, or it's not at least contributing but most used turbos (at least from my experience) have a bit of play in them without significant issues.

I've experience with just the one turbo leaking oil and it leaked a lot, shit everywhere. There was no doubt.

Dunno mate. Just spit balling.

I had a compression test done last year when my first concerns about it came to head, and was all good. The only smoke from the exhaust is soot. No white or grey smoke at all. One of my customers is a Garret dealer and I spoke to him a while back and he seems to think it the turbo.

Most of the driving this Patrol does its towing, and I have notice this is when I find the intercooler see’s a lot of oil.

I am going to ring my customer tomorrow and have another chat with them anyway.

So I’ve gotten as far as everything is unbolted from the turbo, just the four nuts that hold the turbo onto the manifold.
These bastards won’t budge.
Am I better off removing the manifold with the turbo on it?

If I can...

There ain’t a lot of room there.

Give it a good soak at least overnight hopefully will do the trick. Can't remember the name of the place but when AB had dramas with his turbo they had the facility to do full bench test with everything hooked up. They're in Baysie from memory night be worth getting them to have a look. . Has it done it from new?

Well, turbo is probably the easier of all the possibilities to fix anyway.

Probably less headache to deal with the 4 bolts/studs at the turbo. I'd avoid removing the manifold unless you have too, just a whole bunch more studs to risk breaking. There's a couple painful manifold studs too from memory, one stuck right near the firewall with limited access. Did mine not that long ago.

Just on that, I'm pretty sure one of the turbo studs on mine took all the thread with it and I ended up just drilling it through and replacing with a bolt. They were stuck tight.

Thanks. I can't even see one of the nuts holding the turbo on. So stuffed if I can get to it. I'm assuming I can. It hasn't done this from new but its probably been a good three years I reckon when I first noticed this.
I'm going to have a chat with Peter at RM Turbochargers today and try to gauge what I should be doing.
