Had the same thing happen to my B1, put clear line on the returns to test it and my engine was pulling a vacuum up the return lines. Dropped the return below oil level in the pan fixed it.

Area wise, one .040 feed hole to each head is about the same as eight .014 size holes(as if you were pushrod oiling and restricted the feeds to .014).
