weird grease in electrical connectors

[atarimike]

I've been checking some electrical connections that seem to have failed, and I've found they're stuffed with a weird grease. It doesn't seem like dialectric grease, its more of an axle grease or something. I think as the grease ages, the connection gets shorted. I found this is in the EGR plug before, and now in the overboost sensor plug. Neither worked.

Ford didn't do this, right? This is "prior owner syndrome"?

it should have the white grease in it, not anything that looks like wheel-bearing grease. In all my connectors, it's still white after 20 years.
Maybe a Previous Owner just figured grease was grease.

Could be cosmoline. It is mainly used as a waterproofing and barrier and not as a rust inhibitor and I have found it on several connectors on several cars.
