You just reminded me of something that I always wondered about... and you answered my question too! So maybe 20 years ago, Chrysler put out an updated oil pressure sender pigtail for a lot of their mid and late 90's cars. They had problematic and leaky oil senders. But anyway, the updated pigtail had a tiny little hose coming out of the connector. I always wondered "how the hell is that supposed to improve anything"? I thought it was really dumb.
But now I know why! That hose vented the leaking oil and kept it from pushing up the strands of the wire and ruining it. Of course, I guess it still didn't matter much because those cars were terrible with underhood wiring anyway, lol.
I had a 1992 Escort (essentially a rebadged Mazda) that had the speedo cable wicking oil into the panel and down onto my leg problem once. Never seen anything like that before.
And of course anything British just leaks oil as a matter of principle. My current 1970 British project drips oil on the shop floor (4 to 6 drops a week apparently) despite not having actual been run in well over a decade and the engine being dry for that time (its the transmission thats leaking and replacing the gasket likely to be the issue would involve splitting the entire transmission casing, for 6 drops a week I'll live with it for now).
My parking space under my Suburban used to look like a crime scene from transmission fluid until I replaced the vacuum modulator, now it just looks like a bad circular saw accidedent happened under there.
