i have been collecting information on the -fte engine for some time now and maybe i am not looking in the right places because my searches haven't been very fruitful. i have not found a document with all the engine information needed for a standard rebuild. i do have one for a 5e-fe but not for the -fte. many have said that they are basically the same engine despite a few differences here and there. my concern is whether i can use values such as the ring end-gap, main end bearings and crank tolerances from the 5e for the 4e.
i'm guessing the reason i haven't been very lucky finding out this is because most upgrade to the 5e block anyway..?
