Knock Sensor

sleepydsm · 08-01-2005

After pulling the head, I inspected the knock sensor. The back of the sensor seems like it exploded. There is a trail of the melted backside on the back of the block. I am assuming that is not good for the sensor (to have the back of the sensor gone, its like this black stuff)? Anyways, what caused that, and how much does a new sensor cost? Thanks!

That's normal after a while. The goo they put in there melts and the thing is shot.

So if I have a trail of what looks like hardened blood coming from my knock sensor bleeding down the back of my block the knock sensor is bad?

i'm gonna go with yes. stick your finger on the back of it, and it it's not there, then yeah, i'd replace it and get a spare for later if it was 5 bucks. can't even see a movie for that little anymore.

I've got a knock sensor on a 90 block that has no insulation visible, guess i should get a new one? Anyone have any for sale? And then i have to find the right way to attatch it.
