I recently put five quarts of oil in the engine just for it all to leak out. I noticed the leaking when I was pumping gas, the leak is underneath the front of the engine. I just can't figure out where.

Hello,

For a large leak like this you should be able to look under the vehicle and see where the oil is dripping out of.

You can also use oil dye and black light, which can help you pinpoint the leak.

Take a look at this helpful guide. Go through this and let me know what you find.

Thank you, that was helpful. It's the oil pressure switch. It's so small I don't understand how so much oil can leak out of there. How do I replace it?

Glad you found the issue. Replacing the oil pressure switch is fairly straight forward. The pressure switch screws into the engine. So, all you will have to do is first disconnect the wire then get a correct size socket to fit over the sensor and loosen and remove.
Most auto parts stores will have oil pressure switch sockets that you can either buy or rent to use. Unfortunately, our catalog does not mention the socket size.
