First thing, get a compression test on the cylinders.
If it is oil then it could be worn bore/rings/piston. A compression test would rule a lot of that out.
It could also be the o-rings around the spark plug tunnel or the seals between the rocker cover and spark plug funnels. Is there oil dripping from beneath the exhaust port #3?

Well the reason it was not running was because fuel pump was not working.. but i took the head off aswell and it looks like theres surface rust on cyl3?? Im sure it was running on all 4 before it stalled so how the heck is there rust in there... unless it has started to rust when the bike stood for 5 days before i took the head off.. anyway here is a pic
