Yep. Clean breathers, then replace gaskets. Easy enough job. I managed it

If you want to 'walk tentatively' or even economically - the issue which causes the leak is breathers are blocked, which causes excess pressure inside the camcovers, causing an oil leak/weep. So..
in theory this being the case, you can unblock the breathers, the pressure is reduced significantly, and the leak should stop.
In theory.
The general consensus is to clean breathers, take the camcovers off and replace the gaskets, however, I'm going to go all renegade here and propose an alternative course of action. The price of these gaskets seems to have rocketed in recent years, so I'd get your breathers cleaned - which many recommend as an annual thing, make sure the outside of the engine is
completely clean of oil,
that includes the plugwells, then check back in a week, see how you're doing. If you've even a trace of oil, get them changed, if however you're ok, then you may have got away with it. I'm not advocating doing half a job, as it were, not at all. A gasket failure will kill your DIS pack, which is a 'derrière' of a job

. I just remember my gaskets when they came off were supple and spongy, and in hindsight wonder whether they 'needed' doing. To check your gaskets is simply a matter of pulling an HT lead out and shining a torch down there, so 'no biggy'. You should be checking the plugwells for oil after doing the gasket job, just in case even the new gaskets aren't sealed and require a further 'nip'.
Obvious things like make sure the covers are torqued up correct etc goes without saying, if you choose to do the gaskets.
I suggest my 'renegade' course of action purely as you mention 'short term' and also the leak appears to only be very slight at this stage.
