Hi pal,
Do you have the following part? It's the rigid pipe (and connecting nuts) that runs from the power steering pump all the way nearly to the back of the engine bay.
My garage says that the pipe/nut has seized at the point where it connects to the pump (see pic 3) and as they try to undo the nut it starts undoing at the pump casting itself ..... they can't get any heating equipment in the confined space to free it and if they put any more pressure they say the pipe may snap leaving me without p/s.
Two more pics showing the route of pipe (all needed).
Thanks,
Rich
