Anybody seen a knock sensor leak like this:
 It's like the back melted off and drip down on the block. The sensor worked when the engine was running but I thought I'd ask. -------------------- 92 Eagle Talon TSI AWD "The Black Golfball" How fast can a 14B go???

I've seen a few of them like this... I think they get hot over the years and the filler melts out.... not sure what it is for sure. I've seen them work too, but I'd be replacing it.

The fluid is a viscous damper, it filters out extraneous engine noises/vibrations. As the sensor ages and the fluid leaks out, it becomes more and more sensitive to both phantom knock and real knock.

yeah it definetly needs replaced.
You can get a new factory sensor from Advanced Auto for cheap. All they do is rebox the factory sensor. It even has the Mitsu sticker on it. -------------------- 1992 TSi AWD, Auto swapped

QUOTE (wortdog @ Mar 12 2006, 08:26 PM) As the sensor ages and the fluid leaks out, it becomes more and more sensitive to both phantom knock and real knock. That could explain some of the knock issues I had last year. Or it was the crank cracking!  Hult250R I take it you haven't had any issues with a non-OEM sensor. I thought OEM knock sensors were recommended. -------------------- 92 Eagle Talon TSI AWD "The Black Golfball" How fast can a 14B go???

I used this one on my GSX and had no problems with it, plugs right into the factory harness, and cheaper than what advance had them for around here.

90GSX, the pic in this thread is a knock sensor, not an o2 sensor.
 I've also seen several of those leaking. That flat-mouthed bastard eclaser has one in that shape on his engine, and I recommended having it replaced, but I wasn't sure if a sensor from the Zone or similar places were worth a crap or not. OEM is always a safe bet, I guess.

^^^^I'll have to try that too.
If I have to replace it later I will. But I need to get the rest of the engine built and would rather concetrate my financial resources on the stuff I absolutely need. -------------------- 92 Eagle Talon TSI AWD "The Black Golfball" How fast can a 14B go???
