I have a 2002 golf mk4 estate with a 1.6 sr petrol engine. Recently discovered a big vacuum leak coming from the intake manifold. Bought a whole new manifold second hand. To my surprise I am struggling to find a garage that will fit it for me. Not got much money to spend on the car and very close to attempting replacing the manifold myself. Anyone know if this is a difficult job or if there is much specifically that can go wrong? Any advice would be much appreciated!
