Sean,
Not got the manifold off yet, ran out of light today. Got the fuel filter, bracket and all the pipes off, the solid fuel pipes that run through the manifold off, power steering tank and pipes off and most of the fixings but at the rear of the engine the loom and the gearbox dipstick go through between no.4 and 5 ports, i take it i need to completely remove them to gain access to the fixing bolts and allow me to remove the manifiold?

Also, once it's off, should the flaps move freely? or if there's nothing obvious with the flaps / linkage, is there any way to tell if it's definatly the motor?

Cheers, Gary.
