Removing oil pressure sensor, again

Removing a/c compressor and the removable part of its base still leaves little room to get at the oil pressure sensor nut. There is a support bar for the a/c behind the sensor that prevents getting a crow foot around it from behind. In any case, the 2 crow feet I have that will fit (1" and 24mm) seem to be too thick to grip the nut with out also gripping the block below. Even getting a crow foot around it, it will not budge.
So now I have loosened the camshaft oil feed line and hollow bolt that goes into the block, causing the loose block to flop over to the rear of the car. To complete the job of removing the nut that holds the camshaft oil line on to the hollow bolt that goes into the block, I am going to have to go off to Sears to forage for a 14mm spanner with a ratchet end, to give me enough movement to unscrew it. Sorry to be so long winded about this, but I have two questions before I take a leap of competence and detach the camshaft oil line:
1. Once I unscrew it, can I just bend it to one side to remove the hollow bolt that goes into the block? Seems to me that bending a metal oil line might not be wise, so how do I get it out of the way?
2. When I reattach the oil line, should I use something to prevent leaks? I think someone suggested teflon tape, but isn't that for plumbing and would not stand up to heat?
Since I am taking the car to my Porsche mechanic on Wednesday for an a/c recharge, maybe I should just ask him to install the sensor, particularly if I am risking damaging the lubrication system. Its that stubborn "I can do this" mentality that has got me into trouble before ...

you can do this. you did the right thing by getting the AC stuff out of the way. forget the crowfoot. once the sender/block are in the vise, you just need a long open end wrench. they are bloody tight sometimes. loosen the oil line at the cam tower to allow easier movement of the line. if you have late oil fed tensioners, the little metal oil line needs to come off at the upper connection to move the line out of the way. don't bend it. you can loosen the AC support bar and move it for more room to work. just remember the angle the pieces were on. no teflon tape. just tight fittings. on alloy cases, be careful to not over tighten the long fitting that goes thru the sender block or the threads can be damaged in the case. use new seals if you have them, but the old ones will do if you don't.
