Hello,

Okay, so this is a common problem with oil sending units. The best, and really, the only way to fix this problem is to simply replace the oil sending unit with a new one. To replace, unplug the electrical connector and unscrew it from the engine block. Installation is the reverse of removal. In the diagrams down below I have included the Original Equipment Manufacturer[OEM] part number for you. Please get back to us with how everything turns out.

Thanks,
Alex

Hello again,

Okay, I'm sorry. That's my bad, I thought that we were working on something else. In the diagrams down below I have included the instructions for the removal and installation of your vehicle's Engine Oil Level Sensor/Switch. It is from the vehicle manufacturer and is pretty straight forward and easy to do. Please go through this guide and get back to us with how everything turns out. I hope that this helps.

Thanks,
Alex

It's coming from right under the screw that is holding the oil pressure sensor down. As seen in picture.

Hello again,

Okay, well see if you can tighten the bolt up and stop the leak. The torque value for the bolt is in the diagrams that were dent earlier. If it torques down and stops the oil leak, great. If not please replace the oil sender and get back to us with how everything turns out.

THanks,
Alex
