Outer Limits 4x4 Board

My 3.0L GUTD has developed an annoying oil leak on the left rear side (passengers) of the engine I have can't see where its coming from.
I don't want to take it to my "friendly" Nissan dealer, I have no faith in their diagnostic capabilities following recent dealings with injector pump (that's another story)
The only place I can see that it seems to be coming from is from near the turbo but can't get cover plate off.
Any one got any clues

could just be blow by from your crank case being forced through the turbo and it leaks out the rubber joins i have had this prob with my 4.2td.

Spray with degreaser, hose off, go for a drive and look for fresh oil.

Do what Bazzle said & then check the oil filter housing for tightness as they are a cartridge type & can be fiddly.

Have checked around oil filter and housing, it seems to be coming from the turbo. I haven't been able to get to it yet as I've had trouble removing the cover plate, it would appear the you have to remove cooling hoses intercooler and hoses, the workshop manual is of no use at all
