.....hmmm, the 400 small block that I used to have in my '32 did this. So I'm interested in what others say about this. Everytime I'd get on it oil would be ALL over the place! I never really knew what the problem was as the motor blew up before I got it figured out {I'm not saying that's why the motor blew up}. Although when it did blow it broke the camshaft in half because of a bearing seezing so this could be an oil issue. I didn't have baffles in the valve covers so I put them in but it still did it {I tried two different types of baffles but still blew oil out}. Do you have baffles in the valve covers? Twice when I got on it the oil fill cap blew off & once the dip stick flew out! Someone told me it could be because the rings weren't seated so pressure was getting past the rings & into the oil pan. Then this pressure would release up to & out of the oil fill tubes. But what this was have with replacing a cam is beyond me.... Again, I'm interested in what others say..... good luck... Bill
