There's an oil breather tube under the inlet manifold connecting the crankcase to the inlet
It has a spring on the bottom so you need to push that tube down as the manifold slides off the studs

Obv disconnect the fuel rail and the Injector loom underneath the mani

Breather pipe needs two new and well lubricated O rings when refitting.
There's a bit of a clearance issue getting the manifold past the water/thermostat outlet elbow, but it can usually be wriggled by.
