I've got a similar problem on my S2 Cab.Oil leak apparently on the sump gasket blowing onto the exhaust manifold , creating lovely smells.Having messed around for several months trying to cure it ( to no avail ) , I had the nearside of the car jacked up and engine running and saw oil peeing out of the rear of the lower balance shaft housing.Turns out that there is an O ring sealing the rear of the housing around a circular plate.The plate was loose !!. The O ring is £2.95 from an OPC , but to replace it you have to:
1. Remove the exhaust manifold
2. Jack the engine up and remove the O/S engine mount
3. Remove all belts and sprockets from the front of the engine
4. Remove the plastic backing plate behind the belts
Only then can you remove the balance shaft housing to replace the O ring.
So far I have had two attempts and got to the end of stage 2!!
Aiming to do it next month when I sorn the car and replace the belts anyway.
It is a pain in the £*&%* but am fairly sure that is where my problem is.
Might be worth you checking this , as the oil seeps out and runs along the sump gasket to the rear of the engine where it drips onto the exhaust.
Good Luck!!

Cheers Toby but as I said: I have a (partially) rebuilt engine ready to go in.
All seals bar the front end crank shaft oil seal has been replaced*, new water pump, every conceivable bolt and jubilee clip in stainless steel. new belts, new rollers (Continental kit), rocker cover/cam carrier gasket, inlet manifold gaskets, exhaust manifold gaskets, thermostat, oil pressure sender unit, sump gasket, all O rings, new cork gasket at rear of camshaft carrier, engine coolant sensor, oil cooler gasket... etc etc. Basically everything that I won't have to worry about for a very long time and I don't have the concern that the engine will need pulling out or cross member removal for jobs like replacing the sump gasket.
The problem with one of the balance shafts was a) one threaded bolt hole which required re-tapping - I tapped it to 7mm b) the Loctite 574 was a pig to apply - horrible applicator. I wasn't happy the first time, lost half a night's sleep, took it all apart and re-did it.
Those balance shafts are sooo much easier with the engine on a work stand.
You can borrow it if you want
*Could not remove the crank shaft pulley. I figure that if I need to, I can do it when the engine is installed at some future point. There's no sign it needs doing. I have a flywheel lock. I bought all the fitting tools for doing cam and balance shaft belts.
