Funny, but gravity works just as well down here as it does north of the equator <img src="/forum/images/smilies/968/tongue.gif" class="smilie" alt="" /> .
The biggest "real world" problem is that we drive on the [English]left side of the road and our cars have the steering wheel on the right. This also puts the pedals, pedal box, hydraulics and so on on the "other" side of the engine bay, so a bit of care needs to be taken when using "foreign" diagrams, web postings etc.
When I get to Memeber status I'll post a pic of my engine bay and you can play spot the difference.
