Cam position sensor help

[boxsterg]

I'm having trouble locating my cam position sensor. I have a Bentley which states I should be able to access them from the top of the engine, left front and right rear. I can't see either of them on my 2000 2.7. I've removed the air pump and hoses, and the top aos hose to help visibility. I still can't see them even with a mirror. Ii replaced the crank position sensor in about 10 minutes but I'm having trouble finding these. Anyone out there replaced these. Do I need to remove more things to access them?
Pics I've seen are such extreme close ups that I can't get my bearings. Seems
Like the right rear one may be hidden behind the aos. Any help greatly appreciated.

Thanks,

Garry
