Mine did not. But the oil leak followed a similar pattern as yours. Appeared to come from front. I re-did the oil cooler lines, checked the oil sending unit under the filter housing. Re-sealed the left front corner oil pan bolt, finally using a Doti washer. Sometimes I would take car out and drive it, then park for days and no leak. But when I'd get on it, that's when I would smell a whiff of burnt oil coming into the car. Then I had a small pool of oil by the cam cover bolt right next to the passenger side vent tube. I had used the Scotch Brite for the vent. Finally removed cam cover and replaced w Haibeck's foam material.
No more leaks. No burnt oil smell. That was my experience.
The pressure was causing multiple areas to leak.
