Sounds like either your running a bit of a rich mixture or some oil is getting up to the plugs..  are you burning any oil?  and what's the air intake side of things like..blocked airfilter? need changing etc..
The plugs should look a browny grey/white ish colour around the electrodes but not wet.. if they're black and sooty looking that's likely an over rich mixture.. if they're definitely wet then could be oil, although i tend to think that's less likely on these engines unless severely neglegted..

Just the leads.. missinterpreted your post sorry,
I guess then unless it's usual grime and grease or wd40 best just run the engine and see what or if anything is blowing/leaking/getting onto the leads..
Also that everything else is behaving normally, engine warm up/running temp, no loss of oil etc..

i don't lose any oil really... engine does look a bit oily at bits but always has done and mechanic has always said it was fine, runs sweetly too.

With mine the dipstick holder cartridge area gets kinda dirtied up, i assume by airflow and heat grime from the alternator and belts etc..that's pretty normal but if you have any doubts about the leads then maybe replace them.. sounds like it's basically ok.
