Why do my speedo cables puke gear oil?
I put a new cable in my daily and just like the last one and the track car, they puke gear oil out the fittings at the cluster, all over my pants. This one lasted like two months, now it bounces. WTF?

I had an internal leak on one not in a miata but in a civic. It did almost the exact same thing. First I drilled a small hole very carefully in the cable housing about halfway up the fire wall to let all the oil drain before it ever got to the gauge it helped a little I ended up replacing the speedo drive unit on the trans from another one I got used and it went away. I had replaced all the o-rings I could find and it seemed that something internal to the drive unit has a seal on it that went bad. Still going strong to this day that was about 4 years ago.

There is also a seal inside the sender thingamajig also I would bet. The round seal is really only to seal the female part of the cable to the male part of the sender so that fluid doesnt leak out of the trans that way. If its traveling up the cable then the sender seal (internaly) is compromised or (I would have to look at it) but the cable might also have a seal in it?
I could be crazy though.

This doesn't help The Hustler much, but I just want to thank him for exposing all of the car's weaknesses for us. Have the engine and tranny pulled right now and, since it's so accessible, I'm refreshing the speedo cable O-ring and oil seal and checking the vent. Makes me sleep better at night.
