how difficult is it to swap out the housing? I just cracked mine
doing something stupid.. is it a matter of a few bolts and its off?

I know I have to remove the lower timing cover, but i dont have
to mess with anything else do i other then the connected stuff.

The timing belt pulley doesn't need messed with does it?

 

Gonna answer my own question incase someone else needs to know in the future. The lower timing belt cover must be removed to get this housing off, which involves removing all accessory pulleys
