Hi, I'm looking at topping up the gearbox oil on my 106 and have done a bit of reading around - I was hoping to top some up through the breather hole on the top of the gearbox, which I know isn't the best way to do it, but I'm hoping it works just for this once. I'm only thinking of putting in 0.5 litre to see if it helps with a noise I can hear, so not much danger of overfilling it. Garage recommended oil could be the culprit. I just wanted to check that I've actually found the breather hole though, and I'm not just going to be tipping oil in the wrong place! I've taken a couple of photos, does this look the right one?
