Right been over to the inlaws' house to actually get it off the road and on their drive. Can't tax it as already mentioned so its off the road until I get my V5c which will be January, plenty of time to mull it over.
It starts and runs, checked the oil and it just about registers on the dipstick but on a hill, figured it would be enough for now and drove it up the drive. No issues there.
Had a look underneath and oil's dripping just above the PAS ram and down the subframe, which confirms my suspicions regarding either turbo or oil line failure, the fact oil's in the exhaust is telling me a seal's probably gone on the hotside, the inlet's clean. If it IS the turbo, i'll buy another one one day, but given that I can't drive it anyway for a good few weeks i'm in no rush to get out under the motor in the cold. There's no oil on the top of the turbo, it's all on the return hose underneath. It COULD be that the return was too restrictive and pressure has built up in the turbo, don't know yet though and no point speculating.
When it goes back on the road i'm turning the boost down. Remember I was having actuator issues using the T2 one so next time i'll be going all out with the Kinugawa actuator and getting it set for 30psi max, and turning the fuel slightly. Think a contributing factor was the boost spiking, I saw the gauge hit way over 30psi a couple of times on the run and there was no smoke on boost. I had fuel turned right up on the T2 but was an old fuel filter, got much more smoke when I replaced the filter and cleaned the pickup, so I think it's overfuelled for the application, spiked the boost and maybe whatever else.
Still, on this more extensive test run, i KNOW the turbo's epic,roads were a bit damp so not a good indication but the thing screams, an estimated 30-70 pulling onto the motorway (on a slightly uphill sliproad) just before it went pop was about 6-7seconds, two up with my tool bag and a quarter tank. Pulled at silly boost all the way through 3rd, only went pop when I matted it in 4th.
And i've decided that 1st and 2nd gear are now irrelevant. Just end up going sideways
