It happens. They dry out and weep.
Four bolts on top to remove, no water jackets or anything crazy. Heres what you'll see when you pull it off:
WARNING: Those four bolts that hold the cam cover on... DO NOT OVER TIGHTEN. They are only tightened to 5nm which is less than most will do by hand. They have a stop/step build into the bolt but you can easily shear them off if you try and over tighten.
Ideally you'd replace the cam cover gasket and the four seals for the bolts. Something isn't letting that gasket seat and seal. It may have dried out or who knows.
Some have ran a small bead of RTV around it. Not a bad idea if you need it running ASAP.
When I swapped mine (before the engine build) I lubed it with engine oil (like you would do on an oil filter) and just tightened to 5nm. It was fine till I pulled it off this last time and it sat in the garage for a month.
