Other way around peeps.
First facing down hill
Reverse Facing up hill
Driving an engine over backwards with timing chains is a big no no. With no oil pressure to hold chain taught with tensioners there is the potential to jump teeth. You'll get no more resitance putting it the other way around either.

Anyone care to explain the difference between forward and reverse in these situations
. Call me a blonde but there really shouldn't be any difference whether you are in forward or reverse, the only thing stopping the car is the compression of the engine.
Either I, or you lot should hang your heads in shame.

According to my old man - the car should be in the lowest ratio gear so maximum effort required to move the car the smallest distance. This is normally reverse for uphill and downhill. However can see the argument that an engine should not be turned backwards. Fortunatly in Lincolnshire not a big issue!

I agree with this.

Not "driving" as in
, but driving as in turning the engine if the handbrake fails and the car should start to roll. Which it won't anyway if anyone who has ever tried to push a car in gear with the ignition off will know.
What we mean is any force acting on the gearbox and transferred to the engine when stationary. When the handbrake fails it is better if it acts on the engine/gearbox in the direction it is designed to be. For instance it is better pushing with the gear than against.
Either way it the car won't move.

You must be still having a blonde moment. If you park on a hill facing uphill, it wants 2 be in first. If you are pointing down hill, then put it in reverse.
