My '30 CCPU was "restored" in Minitoba, Canada. The guy who did it chased the banjo threads and I had that problem but it is easy to fix. I drained the oil, flushed and removed the bolts one at a time, I then used brake cleaner or carburettor cleaner (could use wax and grease remover) on a strip of rag to clean the thread. I did the same to the tread on the bolts, put some Permatex No 3 on it and screwed them back in. now, 9 months after returning the oil to the diff, it hasn't leaked a drop. I think we sometimes get a little precious about how things should be done, especially when we think about how these cars have been treated during their "just another old car" days.
