Help! What I done did?
 

It's a 72, I removed/cleaned/painted,etc the oil tank and lines, although I did not remove the breather lines from the body. Upon restart I've got a massive leak from the air cleaner housing. Could I have reversed the breather lines? I'm just getting the car ready for the painter and don't need to be messing around with an oil leak!:(

Is it possible you overfilled the oil tank?

I think that's what I did. Thinking back, I didn't drain the sump, and when I finished the job I put 9 quarts back in! The oil, before more leaked out, was nearly to the top of the tank! Goes to show the danger of starting a job and not finishing it until months later. You lose track of where you were. Thanks.

I did the same thing...no one here is ever alone.
