I had the tray off of the underneath of my Classic the other day, and noticed that there is a rubber hose that leads from where the oil filter fits, this tube had an oil drip on it, is this normal, and where does the hose take the oil to....

The hoses going to/from the "filter mount" actually carry coolant (the filter mount is a heat exchanger). Thus, if you see a drip of oil on one of them, it can't have come from inside the pipe concerned.

It could be from a number of places (leaking down from a camshaft seal for example), but the likeliest source (especially if it's the lower pipe) is from the filter seal itself, so it may simply be that the filter needs tweaking up.

Alternatively, it's possible that the gasket sealing the heat exchanger to the block could be leaking, allowing oil to drip down. The heat exchanger and filter are held on by a single hollow stud which can sometimes work loose, so this is an area to check.

If you get under the car with a torch, you should be able to follow the oil to its source without too much difficulty.

If you find the leak is from the heat exchanger/block joint, remove the filter and you'll find a hex machined into the stud, which you'll be able to check for tightness with a dogleg ring spanner or similar.

Cheers Greasemonkey,
I guess I should change the oil since I did a trackday recently, I'll check it out properly then.
