The wire to the 02 sensor wore a hole in a power steering line. Dealer couldn't tell me for sure what thee line was called but one end screws in the back of the rack and has gaskets with it. The other end screws into the rack on the passenger side. The end closer to the passenger side looked like a flared end. No gaskets came with that side. Replaced the part and it leaks. Looked for help from a lot of different places, hope to find some help here.
