Default 1 question on new ac system

2004 5.4L

I am replacing the whole system, compressor, condenser, evaporator, accumulator, hoses.

Anyway my question is, If I put oil in the system before I vacuum it down, wont that remove some or all of the new oil I just put in? Or should I put it in after vacuum with the r134a?

thanks for any help.

Hold its vacuum good to be sure of no leak, for some time and then charge the system with refrigerant.
