Q: Oil leak on 1995 Cadillac Seville STS

I have an oil leak but the smoke come out through the front grill (mostly on the drivers side)I have had some tell me this couldn't be from the oil pan. I have tried to look
under it. My thinking is it seems to run down the bottom rail of the car toward the front and then gets hot if that makes any sense. I am now having to add oil pretty regular
which I usually added a quart or 2 between oil changes which they told me was norm for this Northstar engine and mileage 165,000 miles on it.
Wonder what your thinking is about this leak???

your car has a oil cooler on the drivers side of the radiator. Check radiator or two oil lines running to the radiator. Lines could be leaking
