Seems my run of bad luck is continuing. The fourth problem in the last month or so is now car related. I'm getting a nasty grinding noise from the turbo area on my ZD30. Seems to quieten down when it warms up a bit but doesn't go away. Boost seems pretty normal (according to the Torque gauge) but not sure how accurate it is. Power is pretty crappy. Anyone know where I can get it looked at around the Penrith area and how much a replacement would be?
TIA.
Check the intake for oilQuote:

Just curious whether it could be the cracked EGR pipe behind the motor near the snail. My noise was first diagnosed as a turbo. It almost sounded like it was spooling up with a heap of sand inside it. But in fact it was the harsh air gushing out of the split EGR pipe.
Thought i'd mention it as it's an easy check and a cheap one to tick of the list.
As above and check your intercooler and piping too. Our old zd30 had a similar grinding sound on start up but would quiet down after a minute or so.
Ended up being a crack in the IC, crack closes up a bit when engine heated up and was hard to diagnose.
Noticed oil residue on side of the intercooler.

Seems it's an exhaust manifold leak....
If thats it its a good outcomeQuote:
