New start up after rebuild

[Lefty Lawn Man]

I just finished putting my truck back together. Had it down to the block.Did HG,ARP Studs, STC fitting, BPD oil cooler,erg cooler,oil pump.Did blue spring kit.Cleaned and bluffed out exhaust side of turbo.Heads were machined and valves adjusted by machine shop.New Radiator(leaking when all got reinstalled).New batteries,belt.Banjo bolts(6.4),turbo feed tube...I'm sure I left somethings out...

Truck will start after long delayed cranking. I have good oil pressure.White smoke(air in system?) Should after several minutes of running...Next crank just after a few minutes stil is a 15+ second delay in start up. I had an exhust leak at turbo exhaust pipe(fixed ). Now at exhaust manifold..Is there supposed to be a gasket there? Don't remember one.. Now I'm worried abou my FICM... I got about $6k already and still need to recharge my A/C When I put the turbo back together (big clamp) I heard a pop as if I broke something.(im hoping the clamp popped over and sealed) Im getting no Turbo reading when I rev engine(new socket replaced and 2 wire were joined off the old connector wires/they weren't same colors and unsure if it was done correct) Hard puffing and white smoke ....
Any tips are appreciated...Thanks!

Before project started I had oil in the degas, lost about 1qt a week in coolant and was getting increasingly longer start times.....
