Knock Sensor Sealing TSB
Is the RTV bead that's shown in the TBS running along the actual interface between the rubber seal and the valley cover hole? Or is is just a damn around the rubber boot but not on the rubber boot?
Why are they leaving the back part open? I'm assuming there is enough slant to the engine that water will only run from front to back?
Why not seal around the entire boot? What about where the wire enters the center of the boot ... is it water tight enough?
I see the foam pieces under the intake manifold are removed so they don't hold water like a sponge.

I usually don't wash my engine, but since the intake manifold is coming off this weekend I might as well address the knock sensor TSB.

As far as total sealing the grommet, I believe the intent of leaving some breathing room is to allow any moisture to escape. I think the biggest issue is freezing of any moisture that might make its way around the knock sensor and doing major damage to the sensor.
Following the TBS might be the safe thing to do, but just my personal opinion, but if I washed my engine a lot I would be inclinde filling the senor area with dielectric greese. It would be pretty hard for water to damage anything if there is no place for it to get in around the sensor.
