left hand engine seals.

[Bretty]

I changed my gearbox over, over Christmas. I replaced all of the gaskets at the time but reused all the seals on the left-hand side of the engine (clutch rod, gear shift shaft and gearbox output shaft seals). They all looked to be in good condition at the time, so I put gasket seal on the outside of them and stuck them in.

I now have a slow leak / drip coming from that side now, which I think is likely to be the output shaft seal.
I've bought a whole set of seals and plan to replace them. I'm now trying to get my head around... How easy is that to do without splitting the engine? I'm hoping I can just pull the shafts out then hook the seals out? Output shaft might be a bit trickier to get out? Will I need to drain the oil?

Hmm
