1Zz-Fe Injector Removal Precautions

[Dmitriy]

Hi All,

Before I replaced bad cylinder head cover gasket some oil leaked through it and accumulated in all 4 injector bays.

Wiping it away without removing injectors is quite challenging. Can I remove the manifold together with all 4 injectors as a single unit to avoid disturbing the O-rings at the top of injectors? What should I be especially careful with when removing and re-seating them back and in particular what is the easiest way of discharging fuel pressure beforehand? (The official manual recommends disconnecting fuel hose from the pump at the tank and running the engine until it stops - is there not an easier way e.g. carefully disconnect fuel hose somewhere under the bonnet and collect the fuel that comes out?)

Many thanks,

Dmitriy
