Trying to fix three annoying leaks (oil temp probe & speedo angle drive)

I just came across three annoying leaks on the car.

1) The brand new oil temperature probe we installed during the rebuild is apparently leaking. Cannot say of this is the washer of it the oil leaks through the probe, but how would you address such an issue.

2) the speedo angle drive is even more leaky which is quite unfortunate given how difficult it is to source one. Oil seems to leak through the swivel nut, but as with all oil leaks, one never knows for sure. Do you have any hint on how to service these?

3) The last one is the vacuum modulator of the gearbox. Seems like the oil is leaking all round the round "capsule". I replaced the gearbox but did nit service it, so cannot say if the modulators is somehow sealed against the case.

Any help greatly appreciated!

 

1) I had a similar issue - you need to drain the oil and the add a small amount of Febi silicon to the thread and a felt washer. If you continue to see oil, then it is from the body of the sensor and needs to be replaced.

2) No experience

3) They are cheap to replace, buy a new one.
