One hell of an oil leak!

Someone here recently removed and restored their 90PS turbo - they might be able to help?

Generally, apart from removal, the only job that the owner can do himself is clean the VNT mechanism but this one won't have one! Rebuilding is a job for the specialist.

Thanks guys.
I'm abit stuck with the oil feed pipe I just can't get a spanner in there with enough room to turn it. So I've decided to cut it off and replace.
The other issue I'm stuck with is the two bolts holding the turbo to the exhaust manifold have splined heads. The third is accessable from beneath and I have removed the 12mm nut.
I'm just off to have another look from underneath but at the moment I'll have to go and buy a splined socket to seperate manifold from turbo.

Don't worry I have no intention of refurbing it myself.
I'll let you know how I get on but my only thoughts so far are that it would have been more straightforward to remove the engine and do it all on the bench as I feel like a blind trainee gynecologist fumbling at the back of the engine!!!!

Cheers

Ok turbo now off. Although the oil pipe nut was slightly undone by my efforts the pipe was stuck in the union and destroyed the pipe. The two bolts through the exhaust manifold are 12 point and require the correct 12mm socket to fit.
I now understand why elsawin talks of removal from underneath. It is actually possible to attack the two bolts with the exhaust and inlet manifolds still on. The turbo then drops down but the driveshaft needs to be unattached from the engine end to create enough room for removal. Apart from the driveshaft removal that makes it only 7 bolts/nuts + the oil pipe.

Down to Audi today and have ordered all the bits I'm going to replace putting it back and the turbo has gone off to AET for refurb.

I haven't followed the oil pipe all the way back yet, I want to see what the new one looks like before dismantling any more and besides I want a day off.

Hopefully it will all go back on reasonably easily (ha ha)

Cheers

Apologies for the thread resurrection.

My project car (02 reg AMF) has a serious leak down the back of the engine that has resulted in an MOT failure and it seems to be the usual suspects. The pipe that runs around from the intercooler has always been pretty oily inside, and I'm reasonably certain that the oil is leaking out of the turbo due to it being knackered, then accumulating & leaking out of the wee drain holes in the EGR down the back of the block.

As part of the planned refurb, I've managed to accumulate so far a refurbished Garrett AMF turbo, turbo feed oil in and out pipes , an exhaust manifold with EGR pipe and an EGR as well as the various gaskets needed to link that lot together. However, I'm stuck on one significant issue because (for once rather than in spite of) the 7zap diagram.


Although this is a 3 cylinder engine, the diagram shows a 4-cylinder exhaust manifold and turbo, which have a different flange to the AMF one (trapezoidal rather than triangular). This means that the nuts and bolts are I assume not directly applicable. I think I've picked up that there are some 12-point spline-headed bolts (M8x46?) and possibly nuts as well, but I am really not sure about what fixings I should be getting to join the relevant bits together (presumably some or all may need replacing).

Does anyone have any better ideas or suggestions?

It's just a generic drawing. The part numbers should be correct though. The only items that need to be renewed are any nuts fastening the turbo/manifold/exhaust. You should use the special Audi/VW paste with the new nuts; taking things apart may explain why! If the nuts won't shift, use a nut splitter.
