CA18DET oil spitting around rocker cover

"ok there is a small oil leak under boost around the front of my rocker covers near no1 spark plug on the CA18DET its as if its spitting it out from somewhere but it is not clear to see where from. i have replaced the rocker gaskets and they are all torqued down i am at a loss its really weird there is also a mist from the exhaust on the road looks like a sludgy oil sort of effect but this could just be the fact the engine hasnt been used in over a year not sure. im at a loss with this all vacuum pipes have been checked for blockages and i have cleaned the pcv valve i simply cant find any reason to cause this. any one have any ideas for what i can try? Pics of what i mean. "

Fixed, it was a warped rocker cover, replaced and oil stays within the engine now
