I have a 98 Neon SOHC. I have a leaking oil pressure sending unit and I was wondering how to fix the leak? Do I have to buy a new one or how can I stop it from leaking??

get some thread sealent. It's a white gooey paste. You can find it at places like Pep Boys. Clean off the threads with a solvent (on the sender and the block). Then put the goo around the threads on the sender and install.

I'd replace it. I did on my 95, the part wasn't too badd but I had to also get a big socket for it.

Anyone know the size socket required to remove the oil pressure sending unit???? I am sure it would have to be a deep well. Right now this is my only car and I need to get this fixed any help please??

1 1/16 deep or open end

The thread sealer can be found at pep boys. when in doubt, just ask the sales clerk. Avoid the teflon tape. I'm pretty sure you'll find the permatex brand.

Are you sure its leking from the thread and not round the terminal plug in which case you'll have to replace it.

my stock sender is solid brass all the way to the nut. There's no way oil is getting in or through it. mine is a '95, so I don't know if they changed over the years. It's a binary switch and isn't connected to the PCM whatsoever.

I got it replaced. It was leaking arount the part where the metal and the plastic come together. And FYI the socket required is a 1 1/16 but it needs to be a 6 point not 12 otherwise it won't grab the sending unit. Thanks

not too strange. the 2.4L DOHC in my Stratus is doing the same thing. Light's coming on and everything, but I have oil pressure and the temperature is normal.

I even have the part, I'm just lazy about fixing it right.
