knock sensor leaking
I have the passenger knock sensor leaking. Can I back it out a little and use thread sealer on it? Can it leak through the housing? If I remember correctly it is a solid screw and should only be leaking around the threads. Any help is appreciated.

Thread sealants are specifically discouraged with the knock sensors. Use of sealants can interfere with the sensor's frequency or amplitude response.
The sensors come with a special treatment on the threads to seal them. If you can't get your KS to seal properly when tightened to the recommended torque (14 lb/ft, if I recall correctly, but verify that), I'd suggest you spring for a new KS, and that should solve your problem without creating any new ones.
Be well,

Folow that direction and get a new one and don't overtighten the old one USE a Torque wrench.
Thanks,Matt
