Swapping Engines
 

I have a 05 Mini with 71k miles on it that has been wreck and a 06 With a bad engine in it. Going to swap the good engine into the 06 and would like to know if there will be anything needing resetting after I do the swap? The 06 engine has no compression on cyl 3. Should the engine run on 3 cyl with no compression on 1 cyl?
