You will likely find oil puddles, from the size of a quarter to the size of your hand on your driveway in the area that corresponds to about the back of the engine compartment where your car has been parked.

However, in some cases if the leak isn't bad yet, it will only leak while the engine is running. To tell for certain, use a degreaser/solvent on the oil pan and all around it - wherever you see oil. Then, let the vehicle run for a good 15 minutes and see if you can tell more clearly where the leak is coming from.

If it's dripping out of the seal and/or off the bottom of the bell housing towards the back of the oil pan, than it's very likely this is a rear main. Also, validate the oil is black and not red. Black is engine oil, red is transmission. If it's red, then you have a transmission issue and it's not the rear main.

Can you use an oil stop leak to fix an rear main seal leak?

rear main seal must be replaced. also, is it leaking because the crankcase is holding pressure? your PCV is supposed to prevent that, to keep the seals from bolwing oil. if it got clogged, the rear main was the first to give, but wont be the last. once a seal blows ANY oil it is all done. Is PCV clogged? Are other seals leaking. Replacing seal not complex, but plenty time-consuming. The transmission is backed out or removed completely. The torque converter or clutch is disconnected from the flywheel or driveplate, and the flywheel is removed. the rear main seal is removed and new one drifted in. 3 hours in a shop. good time to replace clutch or torque converter if problems there, too. Oil stop leak is not a versatile chemical. It can do as many bad things in there as it can do good things. Most people will tell you they have never used it and gotten the result they hoped for.

Water pumps fail due to a bad bearing and/or shaft seal. Look at the bottom of the pump. There is a drain hole in the casting below the shaft. If the seal is bad then coolant will be leaking out of this hole.
