Knock Sensor Question
Buddy has a '98 VERT. His car has been throwing a knock sensor code (P0327 - Front Knock Sensor) and he wants to swap them out. After calling FRED BEANS there are apparently two different sensors for this year. There is an old style with a locating tab and then the newer sensor that replaced the older style sensor from mid-90s. Is there a way to tell whether you are running the older style or newer styles without removing the intake? VIN check maybe?
Will it hurt the car to run the car with a bad knock sensor?
Anyone have any feedback on this? Thanks in advance.

There is most likely water/moisture in the well for the sensor causing it to short out. You may be able to save the old one. Either way, I recommend using RTV Silicone sealer to seal the well plug and prevent water from getting down into the well. Washing the engine is risky cause water frequently gets in the sensor wells. When you remove the manifold there will be lots of sand and dirt in the space between the manifold and the valve valley close out plate.

Also add a small "dam" of RTV around the front side of the sensor to keep water from pooling around the sensor when washing. When you drive the car, the water will drain from around the sensor and run out the back. It seems to work and GM has this as part of the TSB.
