Stan,
I assumed you meant to say conductive, instead of nonconductive, since 3M makes
a conductive silicone grease. Is there also a nonconductive version? (I know little
about this stuff, but plan on getting some tomorrow if I can find it).
I always figured it was better to have a conductive grease, as it can possibly lower
the resistance at the connector by increasing the contact area. But this only applies
to single conductor connectons of course. For multiple conductor connections as
many of the FI ones are, nonconductive makes sense.
In my case, I find any of the FI connectors with the spring release sealed boots (ie:
the fuel injectors, AFM, temp sensors, etc) are *very* good at sealing out the
elements. My van has an incredible amount of corrosion in the engine compartment
in general (300k km of its life spent in Ontario), yet all of these connectors seem to
have no corrosion when pulled apart. The exposed ground connections are a
different story. I snapped the ground bolt to driver side body off a few years ago, and
today the ground bolt to the driver side head broke off as I tried to remove it to clean
the connections. I used the adjacent allan-head bolt holding a metal coolant line
instead, for now. I'm going to get some heavy gauge cable tomorrow & try to
establish a solid ground from the alterntor to the body on the other side, so this
ground should be less critcal.
