Oil leaking from speedo sincor

I assume you refer to the Mini Moke?

Had to ask because I don't think they made a 999. An 848, 997 or 998, 1098 or 1275.

Visibility for a speedo cable change isn't very good and lots of people remove the cable complete with the drive to avoid cross-threading the cable nut.

Over the decades the range of Mini Spares and applications have been rationalised so a longer cable isn't surprising - some Minis had a speedo in front of the driver (long cable) and others a central speedo (shorter cable).

I expect you managed to lose the oil seal that just sits on the top of many of the speedo drives and is retained by the speedo cable nut. It has been a long time so only I think that is right...
The alternative is an oil seal fitted to the drive housing.

When the oil seal is absent or has failed there is a leak but I never knew one that leaked massive amounts of oil - often oil would be pushed up the inside of the speedo cable and has known been known to ruin the speedo.

Is your trans over filled if not you will need a new speedo drive assembly that goes in your trans. You also may need a new speedo cable. Don't forget to check your trans oil level.

Check the gearbox oil level, it may be too high, the oil is traveling up the speedo cable and entering behind the dash

If you have oil leaking from the sensor you will need to replace it.

hyundai getz.,, if you r in phil. try to call me.. i fix it., anyway what kind of oil leak cause many kind of oil looks a like..

Is the oil you see reasonably clean or is it black. The gearbox oil would be cleaner than the engine oil. Gearbox leaks would most likely come from one of the following:-

1. Drive shafts
2. Gear change lever inputs,
3. Speedo cable
4. Reverse light switch
5. Drain plug
6. Input shaft seal (inside the bell housing).

Pig a piece of paper under the car when you park it at night to give you an idea where the drip is located and inspect the area above that position

Ken Budd's answer is incorrect: There is only a potential engine problem when the oil light comes on permanently.

The speedo/mileometer on thge Majesty normally sends pulses to a counter that switches on the oil-change warning light at 3,000 km. If the speedo/mileometer ceases to function the oil-change warning light blinks steadily simply to let you know the pulses aren't getting sent to the counter.
The most likely problem is a broken speedo cable; a new one costs £5.72 from AJSutton and you can easily fit it yourself: Take off the windscreen then reach through the gap above the headlamp to unscrew the outer cable beneath the speedo.

I've got the same problem as you right at the moment with my 1996 Majesty but in my case its the gear unit on the front axle (to which the speedo cable connects) that has stopped working: I'm currently on the look out for a new gear unit. Does anybody have one ?

Chances are slim that Lucas would solve your problem. Lucas only works in certain very select situations. You need to know where it is leaking from first. They can leak from front seal, rear seal, speedo o ring, and or pan. If it is a minor leak it may work.

is it your oil line going up to the oil guage if it's a manual guage it will have a small plastic line running to it otherwise an electric 1 wouldn't be leaking . if it's not that then mayby transmission fluid coming up the speedo cable could be a 20 cent o ring , if your lucky . that's all i can see leaking oil on that car

Dip stick tube has a rubber boot it slips thru, that seals it to trans. If its got a kick down cable there is a rubber o ring on that too, or front pump seal on trans is leaking.
