you do not need to remove the engine to replace the inlet manifold gasget on a ford ka
just remove air intake box and assembly then remove throtle cable and brake servo pipe then the fuel pipes then the heater hose which conects to the inlet manifold which is a quick release connection there may be some wire conectors to release it may be a good idea to mark these connetions with tags with numbers for aiding reassembly
then release inlet manifold bolts then manifold can be removed and a new gasget can be replaced
