Good morning guys and ladies its 06.30am South African time.I am having a problem with my freelander1.8 petrol cylinder head,which i recently bought from a local engineering company. According to my parts supplier it could be that the head that he sold me is a rover 1.8 cylinderhead instead of a freelander one that is why the hydraulic lifters are making a racket and the car has no power since installation .Is there a difference in the cylinderheads that is causing this problem?:fencing:
