Hello, and thank you in advance for your help!

2007 Ford Freestar 4.2 190,000 miles

Recently head gaskets and water pump were replaced. Now, 2 mos later it SUDDENLY has begun to lose oil massively. Workers at a local machanic shop kindly had a quick look underneath to see where the leak might be. It is near the serpentine belt, under that area, but could not see exactly where oil is leaking out. Now, more oil than gas is needed to drive it, so it’s parked. I put a large piece of cardboard underneath when I parked it yesterday, to get the drip pattern and location where oil is coming from. Today I can take a pic to share, if that helps.

Thank You for any ideas!
