i have a question about that say if i borke the sensor on the car and drove it would it cause a major oil leak? i drive a 1998 pontiac bonneville

It depends, it most likely will eventually leak, and if does then yes it could cause a major leak, and without knowing what the pressure is when it drops if the engine keeps going the results could be a ruined engine.

Also if yours relies on that as a fuel inertia switch also as mine did, then on occasion the car won't start.
You can replace it with the best OE sensor for 35-40$, for less you could go with a BWD or something, but I like AC Delco for Oil Pressure Sensors on our 3800 II'*.
They are not hard to replace, I have found an open end wrench is best used on it, as the so called sockets made for it seem to always break them, at least they break them coming out..

thanks for the input will ill look at it when i get to work just gotta see if i should tow it there or fill it wit oil and drive it i hope thats the problem and not something esle

Very welcome.

To be sure I better understand your problem, you did break part of the sensor off right?
Is the red light on the dash gauge?

Have you checked your oil level via the dipstick?

For replacements if not AC Delco I meant to say SMP and not BWD..

I know it costs considerably a bit more, but if you can get this sensor over the SMP or Airtex Wells.

i dont know if i broke the sensor havent looked fully just got home yesterday to a trail of oil coming from it i looked at the dip stick and i was bone dry but i dont know how long i was leaking or anything im bringing it to work now to look at it

To better get a look at it you are going to want to jack the passenger side up, remove the tire, and pop off the fasteners holding the wheel well splash guard in place, then you can see the sensor, and have access to replace it.
