I need to remove the cylinder head (with the engine in-car) and so must remove the inlet manifold before getting to remove the exhaust manifold.

Access to all the bolts is very poor, but one of them needs me to remove the EGR unit first, as Haynes says. BUT I am finding it impossible to get a hex key to the front EGR bolt because the inlet manifold is in the way.

Is there a way around this or is there a special tool? I am thinking of bending an Allen key to a useful angle (in frustration??). I thought of just removing the EGR pipe which might give enough room, but the clip is crimped on and I can't get access to cut that off.

I have never worked on such an awkward engine. Can anyone help?

Thanks, Phil
