Help.........please before I hit it with a big hammer. How do you get the big plastic bit of the engine of a 1.2 3CYL 12V engine? I only want to change the plugs and air filter and I've been stumped by the stupid cover!! It's the girl friends so I don't want to force anything! Also any ideas on why the handbrake ajusters in the drums work or why not in the case of this car? All advice greatly appreciated!
