Slow tapping noise at idle with clutch down MK2 4 speed

Recommended Posts

During a long drive my polo has developed a sort of gentle slow regular tap when the clutch is in and first gear is selected. Could this be a case of low gearbox oil or perhaps the clutch release bearing? No whine or grinding and it seems intermittent, as in I can't replicate it on short drives. I'm in the middle of a very long trip but potentially could get some parts shipped out with a friend in a week. Also what's the stock gear oil volume and rating? Haynes says 2.2L SAE80, is that right and is there a modern equivalent?

From my research Sae80w-90 or maybe Castrol ST90.

 

You can't really drain it on the car and even selector shaft rubber bush leak leaves quite a lot in.

If end-plate was damaged low down you'd see a lot of oil and smell it. Gearbox oil stinks.

 

I'd try to get 2x or 3x  500ml bottles. Sometimes they have a long spout that needs snipping - you can squirt the most in while below the car.  If not on ramps or in a pit, then lower the car, top up via a pipe, (very viscous so takes ages)

 refit fill stopper by hand, raise the car again  and tighten stopper.

or fill in the speedo cable hole until it drips out the filler hole...easier access and can use a funnel
