Just thought I'd write up a how-to for replacing the rocker gasket on the saxo 8v engines, this seems to be a common problem.
If there is oil leaking from the rocker cover and running down the engine then you will need to replace the rocker gasket. This can be bought for around £5.50 delivered off ebay, although I bought mine from a Citroen dealers for just under £12.
This is the problem I had before replacing the rocker gasket:

As you can see it's damaged and leaking oil, this all dripped down to the sump:

To replace the gasket:
Step One
Remove all of the pipes connected to the rocker cover. Also remove the two header bolts which hold the rocker cover down.

Step Two
Carefully lift up the rocker cover, the rocker baffle underneath it and the two spacers

Step Three
Remove the old damaged gasket from the rocker cover. Clean the edges of the rocker cover and the surface which the rocker gasket will be in contact with on the engine.
Step Four
Put the new rocker gasket on to the rocker cover. Start at one edge and slide it all on. This is much easier than it looks.

Step Five
Put the spacers back on to the thread and then the rocker baffle. You may want to remove the coilpack at this point to make putting the rocker cover back on easier. To do this use a 10mm spanner on each side of it. Gently lower the rocker cover down onto the threads and tighten up the header bolts. Reconnect all of the pipes which you removed at the start and reattach the coilpack.


Step Six
Turn the engine on and check for any oil leaks. If there are any then you will need to redo the job and find where the rocker gasket is not fitted correctly to the rocker cover.
Job done! Should take under 30mins easily.
Anything I missed out just let me know.
