Upper Engine Cover - '05 9-5 Wagon
I took a look under the bonnet over the weekend, and found the plastic cover that sits over ht oil bin was capable of coming completely off.
Not the dipstick lid, mind you. Something like this:

It looks like there are two clips underneath, which secure it to the oil pipe. One of the clips is broken, and it appears someone tried gluing it on.
I'd just replace it. That link above look correct for my model? $50 sounds pretty reasonable.
