Sounds like the crank had a failure. Instead of welding the journal they hard chromed it.
The preferred method is to weld the journal, grind the crankshaft and nitride. Nitriding stress relieves the welded area and rehardens the entire crankshaft.
Call Armando at C.C.R, 650-342-0568 he specializes in Porsche crankshaft work and can give you the details.
