340 break in question

Well, got through cam break in, no fuel leaks this time but have a good oil leak thought it was the 1085 NAPA oil filter but it's tight, with engine at 3k it's a good stream. Hard to see at the time but between oil filter and oil pan. Checked pan bolts, they're good. Valve cover seeped a little, don't see any oil trail from that high on the motor. Bob was pretty sure there's no passages low near the filter. Im perplexed, gonna replace filter for good measure and keep hunting. Im open for suggestions y'all
