Nick, Usually low oil pressure is a good indicator, but a qualified machinist will bolt the case together and torque and then measure the bearing landings to see if there is a misalignment.
This is a link <http://www.thesamba.com/vw/forum/viewtopic.php?t=461257> to a discussion on the same question. From my memory the case halves need to be resurfaced, bolted together, heated, then aligned bored.
