John found a chunk of metal in the exhaust side behind the turbine, thinks its a bit of shaft , must have been a litre of oil poured out of turbo compressor side when I took it off.

Also turbo support bracket had snapped so thats being welded tomorrow, ain't paying frauds prices.

I'm renewing oil feed pipe, all copper washers on water / oil feeds, gasket to manifold and oil return gasket plus a few bolts that where rusty.
