So with the engine in and all plumbed up, it was time to test it all in the vehicle. At this point I'd not finished rebuilding the transfer case, but having run the engine previously without the gearbox output flange in place, I knew that if the rear was not sealed, there'd be another pool of oil on the floor! So, in went the gear and tube nut that I'd made. Once tight I was able to run the engine and test the cooling system. Good job I did... I found two probs (linked). With the engine running, the oil from the gearbox started to track up the center of the modified gear.. This led me to check the gearbox breather, which was also blocked!
