Frank uses a bottle.
So long as the tube sits at the bottom it'll suck out what it needs and can return the overflow.

Yeah. Would that explain turbo having oil coming from from within?

Wish I knew. I am so utterly dis heartened its un realI wish I had the foggiest about turbos

In that case
No wouldn't make a difference
That'd be a good shout
I'd guess an oil seal has gone

Very unlikely imo mate, the seal is usually a tight metal ring, i would remove the return pipe chris, and check its flowing ok
I thought they were labyrinth seals

Yes it is frank. Right about to detach the feed and get a video

The seals are those spring steel rings on the right then mate, they dont fail or wear as such, they just let oil past if the shaft has movement/play

Ahh just had a thought. Me and andy used sealent on the oil return. Lo and behold. Not that I think it made a huge blockage there was sealant in the return fitting. Got a drill price and pushed it through. I don't think it will solve this one though. Is there a possibility I am pushing through too much oil? Note I have taken the oil feed from where the pressure sender was?

hang in there chris. know how you feel, I've been through those emotions several times before when things go wrong but you just gotta keep on swimming forwards and diagnose the issue logically.
I had the same issue back in 2011 with the worn turbo seals n bearings.
started clear from stone cold and then goes steamy then misty smokey plus leaking oil behind the turbine bit

normal turbine seals are like piston seals with a straight cut gap and gets worn with a bigger gap or starts to carbon up n stick.
I rebuilt it with new bearings and upgraded to a staggered/stepped turbine seal for a better seal especially with a decat, resolved the bad return pipe fitting and it never since leaked any oil or smoked and shaft is tight snug.
http://micra.org.uk/threads/pollymobiles-rebuild.35251/page-39#post-486823
so I'd suggest as guys said:
unplug the oil return,point into a container and check oil is flowing freely out the turbo (careful u don't run too low on oil), does it stop smoking while running a short while?
remove elbow n check for any oily stains in the turbine,
check the compressor outlet ain't leaking oily mist into the inlet,
open the butterfly throttle and check the inlet mani isn't flooded with oil from the PCV (slight oily dampness is norm),
remove the turbo mani and peak into the exhaust ports for any major oil stain drooling down the stems from worn stem seals,
fit a stock manifold and check if it stops smoking,
if all those are fine then the turbo prob needs a rebuild as a last resort

good point chris
you may need a restrictor in the feed pipe (1mm for ballbearing turbo, and about 2mm for sleeve bearing type)

why use sealant on the return line? tis asking for potential blockage trouble. should be just direct screw-on hydraulic fittings.
fluid will flow out through the path of least resistance. long as ur return pipe flows freely enough to allow the pool of oil to escape downwards to the sump without any restriction or built up pressure, it shouldn't leak much out the seals unless the seals are really worn.
doesn't make a difference in feed pressure whether its from the oil sensor or from the front grub screw cos its exactly the same feed route.
