The water cooled problem is easy, you just have to find the water outlets from the block and/ or heater hoses the factory water cooled units use.
Fried turbo is a hard one, what do you mean by fried?? Blowing heaps of smoke coz the seals are shot?? Noisy bearing from oil starvation ?? Broken fins ??
G'day, It's leaking black stuff, looks like exhaust, between the air and exhaust chambers, but could it be oil vapour?
wistles like a canary, sounds blowy, and only gets 4psi, previosly was only getting 9psi so I think there was a leak in the intercooler, also the factory boost sensor doesn't seem to be working.
after about 3rd gear and 2500 rpm it gets a bearing noise.
have just bought Boost and MAF sensors and a vacuum solenoid, as I reckon theres somthing wrong with the regulation.
The middle section is cast iron, on top is the oil feed and the bottom is the oil drain most likely the feed is leaking but thats going by what your saying. When it cools down degrease and wash it clean and let it idle up to see where it is leaking from.
Its hard to gauge what your boost problem is without seeing and hearing it and it could possibly be leaking out somewhere thru the system like the intercooler or hoses.
See how you go with those censors for now then get back to us with your results
A thought just crossed my mind, I was convinced that using a water cooled turbo would be the way to go, but now I'm indecisive as the question has come up as to this perhaps unnecesarily increasing the water temp and cuasing issues elswere, so my real Q now is; Wich is actualy better oil cooled only or oil and water cooled?
oppinions please.
Oil and water cooled are a lot better and you shouldn't have any issues if your cooling system is intact mate.
Take the hose off the turbo and get your fingers in there and give the fins a spin. If it feels smooth atleast you know the bearings are o.k. As Alitis said. Give a it clean and inspect.
I wouldn't be worrying about what type of turbo is better until you find the issue at hand. Sounds to me a boost leak but not being at the car who knows.
What engine are we talking about anyway?

Water cooling a turbo on a diesel isn't a necessity. They don't get anywhere near as hot than if fitted to a petrol. I wouldn't worry to much about the "extra load" it may put on the cooling system, a water cooled turbo doesn't require to much water to go through it.
When was its last service? And when was the air filter changed last.
Its unlikely the turbo has carked it, but anything is possible. If its run out of oil, yes, or something has blocked the intake and broken the fins, yeah. But I would be looking elsewhere first. Check every hose for cracks. Remove them and check them. Check the IC for leaks. If it's leaking you will see oil deposits on the core.Quote:

Plus what NN said too about the servicing and filter changes...
@"Scotch" I'd be removing the intercooler to clean and test for leaks first, Sounds like you have poor vacuum to me.
Check all vacuum hoses, question what area are you in?.
Is this an ex Telstra or Mine Patrol
May need to fit a catch can. Clean MAF with Maf cleaner don't throw old one away, maybe still good
I gave it an oil change approx 2,000 ago, replaced oil, oil filter, fuel filter, air filter and coolant, used K&N air filter and Castrol Magnatech 15W-40 oil.
I hardly think there could be any consequences related to this.
it was at 82,000 and the sticker stated next service 80,000.
I'm now 100% positive that there is a leak in the IC and have splashed out for a welded high flow newby, when I fit this I will seal the joints as well.
I'm in the Southern Highlands NSW, yes its ex- mine i'm guessing Mckay or there abouts as its got a Mac's body on it. No real bad rust though, so i'm not sure exactly where it came from originally or how long it spent in the mine, or what sort of mine for that matter.
have already fitted a catch can and have cleaned the MAF to no avail. Won't be throwing anything at this stage, I say if it don't make a difference i put the old one on ebay, only when the probs are fixed though.
