Gearbox oil through speedo cable

Featured Replies

Hi Guys,

I run a 1998 petrol 'Felicia' 1.3 litre, low mileage, less than 45000 miles. Having arrived home one day I noticed oil in the centre consul. Thinking that it was the headlamp adjustment leaking I removed the instrument panel and discovered that the oil was in fact coming up the speedo cable. It has made rather a mess in the instrument panel and inside the car.

A new cable was fitted but it has made no difference. The gearbox/transmission oil level is OK. A bit low if anything.

Having been in Engineering for nearly fifty years I started to look for a breather on the transmission unit thinking that this might have become blocked. However I cannot find one.

Is there a breather on the transmission, and if so where is it?

Thanks, hopefully.

nope, no breather on the transmission, it's totally sealed!!! quite a common falut that, oil coming up through the centre of the speedo cable..

There is a breather tube and plug on the top of the gearbox, these get stuck up and then the box pressurises.

?? i thought that breather was for the clutch to allow the air to circulate more freely??

It's under the clutch arm.

What a horrible design, a bit of plastic on top of the gearbox. Done for cheapness no doubt. I had a hell of a job getting the bloody plastic to move where it had rusted in, even with the clutch pedal fully depressed (jammed it down with a piece of wood) and using 'PlusGas'. Unfortunately the damned plug had rusted in and broke off.

Solution was a piece of 8mm copper tube (fitted exactly) 'cut and shut' in a right angle and soldered, the short leg 20mm the long leg 80mm and locktighted into the breather tube. Makes a better job than Skoda's original.

The plastic plug came out when I changed the gearbox oil, so all's well.

Hi Guys

Also having problems with oil coming up the speedo cable. Have located the breather and managed to move it so that it's proud of the gearbox; it was originally flush with it. But it doesn't move up and down as I suspect it supposed to? WD 40 not done anything, any ideas to get the bloody thing working?
