Why do you feel you need to do a leakdown test. The process is just the same as any leakdown test on any other car.

I need to see where all the oil that the car looses (and its not dripping) goes, is it lost through the piston rings, through the valves, where?
Can the leak down test show if its leaking from the valves?

Leakdown test isn't really for finding oil leaks it's to basically show how airtight the combustion chambers are and from there you can identify if the valve guides are worn or the piston rings and what the variance is across the cylinders.

Wikipedia link sill save me from typing it out.

If there is a piston ring sealing issue can't that be a reason to where all this oil is going?

If you are burning oil you can usually tell if it's valve guides when the give it some beans and then back off suddenly and hit the throttle again after a few moments you will get a guff of burnt oil smoke out the exhaust. Usually notice this if you are coming of the motorway onto a slip road and stopping at the junction before moving off again. If it's getting past the piston rings an engine usually burns the oil under load/hard acceleration.

Though this isn't always down the worn components and can be something as simple as a blocked breather system. Also you can burn oil through worn turbo or supercharger seals.

Some oil use is acceptable, the factory guide on my 911 is anything from 0.5l-1l per 1000 miles is within the accepted limits.

Thanx Nige but if this is so, why wasn't there any oil consumption before the 40.000km mark?

Are there visible signs of oil burning from the exhaust?
