Knock Sensors??

[macx]

Anybody know of a knock sensor that will work on a Windsor?

Even if it does nothing more than light an indicator light.

Guess it might have to be adjustable for sensitivity somehow?

Thanks for any info / experiences!

Knock sensors are really simple devices. It is actually called a piezoelectric device. It is a generator like an O2 sensor where it sends an analog AC voltage signal in which the frequency changes with vibration. So you would have to run a device to read frequency and watch what it does.

-I read this out of a dianostic manual.

-money making idea- someone make a aftermarket universal knock sensor with a meter to mount in the car.

The 302s do not have one. My brothers 3.8L out of a 94 does. Goes in the freeze plug hole if I am thinking the right part.

I think some aftermarket blocks have a boss for the piezo sensor that Jason mentions.

The easiest sensors to use are mounted on the sides of our heads.

My 94 Tbird SC has one, and I hate the damn thing. Anything can get it to retard timing. If you would tad the exhaust manifold with a wrench, while pointing a timing light at the balancer you could see the knock sensor kick in and pull timing. I know EVO guys have issues with their knock sensors too.
MSD sells a knock alert part # 8964; I have no first had experience with the device, so I couldn't tell you much about it. Good luck.
