It depends! Where's the oil coming from? Front seal or rear main?
Im not sure its not coming from the gaskets they said something about the the main seal but its leakking like 4 inches away from wear i drain my oil from and it looks like it been leaking for a long time, its caked with oil everywhere. The cuy before me im guessing was putting 15w40 in their to slow the drainage i guess.
Start the engine look at the harmonic balancer see if it's vibrating if is that will cause the main seal to leak (front)
Look for the serpentine belt that is the front of the engine then look straight down at the bottom pulley that is the harmonic balancer
Mine is leaking very little it's about 400 total to repair . How many miles on the car?
The only thing I can say is get a can of decreaser put the car on ramps and clean the underneath then drive it for while. Also check the oil if it's low fill it then after a month ck it again see how much oil you lost. You can try bars stop oil leak that might help
