Easiest way to do a leak down test ?

[5teve L]

A mate needs to do a leak down test, whats the best/easiest way to do this ?

Basically he's bought a new turbo (big one) & it leaks slightly from the rear. Spoke to the turbo company & they say it could be the pressure in the sump not allowing the oil to return to the sump fast enough (gravity fed apparently, didn't know that, or due to lack of back pressure) He has suggested a leak down test 1st rather than ripping the turbo off & sending it back (although they have offered to pick it up & return it FOC if there is no prob with breathers/sump pressurising, or it can just be sent back & checked)
I think i've explained it correctly, lol, does this sound plausable ??
BTW, I have no reason to think the guy has been ripped off with a dodgy turbo as alot of other people have bought turbo's from this company with no problems inc. myself.
Cheers

A couple of pics of the turbo oil leak that I took last night so apologies for the quality of the pic.
You can see in a couple of the pics that the oil is leaking from where the core goes into the ex housing (which is held in place with a circlip by the looks of things no bolts)
