help!-Oil leak

[chrissyg1984]

Hi, I have a 2007 207 S model. I have had an issue recently with an oil leak. First it was out the head gasket, this was fixed but it has since come from the rocker cover, I have had this replaced 3 times and it seems to be ok now except for some oil coming from the bolts!!!! Is this an oil breather problem and as a novice how do I check this? is it easy? Further to this, there seems to be a lot of oil gathering underneath which I believe is from the rocker cover, it seems to pool around the bottom of the engine on the right hand side (if your facing the front of the car) of the engine on the seal next to the exhaust pipe. Could the main seal have gone?

Any help will be greatly appreciated.

Thanks
