Hello all This is my first post on here so i hope that this is correct form. So i have a mk2 Scout with the 2.0tdi manual with the CFHC and im wondering what it would entail to take an engine from a mk2 FL vrs specifically the CEGA and drop it in. im just curious as to how similar or different the two engines are and what changes would need to happen. and whether i would be able to do it and retain the awd? the main reason for considering this is that the cfhc in the car has already gone through a turbo which was replaced and now has a loud metallic rattle when hot, and the occasional billows of white/bluey smoke which ive been told isnt worth fixing, because "it isnt frequent enough to warrant it". Any insight would be greatly appreciated!! Thanks Brad
