The Ford Barn - View Single Post - INSERT ENGINE FROZE UP ! 31 Model A fordoor

2 different engines with the same problem. Rear main seizes after start. Both engines tore down and redone by the machine shop. Could not find out why. Then I was told to fill the valve chamber with oil prior to start. Pour oil down the distributor shaft hole with oil and a bit of MMO a day before starting. Since I started to do this pre oiling I had no more problems with rear main bearings seizing.
