Howdy again,
I did the job on a bright Saturday monring, with lots of light, so that the sun (in the southern sky here in Texas during the winter) shone directly into the engine compartment. Having lots of light really made the difference. The first time I started on this job it was dusk, and I soon realized that it was not the right time of day to be working on the car, especially on this job.
After unbolting and removing the two 13mm bolts, and removing all the flame trap plumbing, I managed to get both hands down into the area under the intake manifold. I carefully wiggled the oil separator while at the same time gently lifting. When I had lifted about 1cm, I stopped and looked under the oil separator (with what little room I had, I found a perspective somehow) and saw the "lip" of the top of the oil return tube. I noted how the oil separator had an extension which was still halfway inside the return tube, but I continued to gently wiggle the oil separator while still gently pulling up and watching the return tube. The tube did move just few microns but still stayed in place. Once the oil separator was free, I simply maneuvered it out of the cramped space and set it aside (on a side note, it weighed a bit more than the new oil separator I was about to install).
I set up the wrench so that I could work with the long extension through the spaces in between the intake manifold passages, up above the manifold, but I removed the air intake hose so that I could see and also to grab the 13mm bolts once they came loose. Once again, lots of light helps.
The o-ring I bought at the dealer is a little green OEM o-ring which goes on one of the returns under the oil separator. That is the only o-ring I replaced.
Getting the oil separator back on was the harder part--manipulating it around underneath the intake manifold was not easy. I had to use more force to put it back in place than I did to remove the old oil separator.
