Exclamation 2.0l L Series Bad running need help

hello new to the site i have a rover 45 2.0l L series engine

running fine so i sold it to a friend he had it 3 days and it broke down he give it me back now i and stuck with the car to repair, it come back with the cam pulley wheel bolt snapped clean off while the engine was running.

day 1 removed the rocker cover, moved the cam the find that all the exhaust valves was squashed shut cracking all the caps couldn't remove them to get to the springs underneath.

day 2 brought a new cylinder head with new gasket, head bolts, valves stem oil seals etc fitted the new head put it all back together started the car up lots of white smoke on tick over soo we had a look at the injectors thinking thats the course of all the white smoke two of the four injectors was faulty

day 3 fitted new injectors so now the cars had a top end rebuild with new injectors turned the key thought whoop no smoke running lovely on tick over but when you put your foot down there's no throttle response then after a few mins the car will start to pick up with a lot of white smoke then die down than pick back up again some times cut out so suck it bk in the drive, when reving up pass 2000rpm the engine starts smoking clouds of white smoke and running lumpy.

car starts first time with no trouble with no smoke only when reving up pass 2500/3000 rpm clouds of white smoke and there is smoke coming from under the bonnet around turbo/EGR valve aswell

is it the turbo ?? or have i missed some thing ?? will a EGR valve blanking plate work ??
any way to test if the turbo works ?? help needed thanks

Unplug the MAF sensor and see if the running improves.

If there is smoke - there is a leak. Often the charge pipe that runs over the top of the engine, but could also be the inlet gasket.

Injectors rarely go faulty. It is VERY common for people to get the fuel pump belt timing wrong. Double check the timing pins slide into both the flywheel and pump pulley at the same time.
