I'm replacing the head gasket on my 01' s80 2.9L and I can't figure out how to remove the rear cam cap on the exhaust side to put the rear cam lock on. I don't want to damage anything. Was curious if anyone had an easy way of removing it? This is my first Volvo to work on so I'm kind of going slow as not to really fubar anything. I've tried a pick to see if I could catch it and pull it out but had little to no luck with it.
