Default Vanos solenoid won't come out. Help!

Just got done with a rebuild on my s50 and I had to install the vanos assembly before the camshaft sensor. I was going to just unscrew the vanos sol. And then install the cam sensor later. Well, now I can't get the vanos sol. To come out. Used pb blaster wd40 etc....still nothing. Any other ideas. I don't want to have to pull the vanos assembly considering I just rebuilt the engine and installed.

did you try a 32mm wrench originally? or did you round it out with an alternate tool? PB blaster is a good penetrant. Open, Shut is the best. if you want, you can try to soak where the solenoid and housing meet and WITH A HAND TORCH heat up where you just sprayed the penetrant, this will cause the penetrant to travel further upon thermal expansion of the metal. ABSOLUTELY DO NOT, HEAT IT UP TO ANY EXTREME temp. please use your head and proper judgment as to what may be too hot for the inner O-rings.

Thank you I will try and let you know what happens. Barrowed the socket from one of my mechanics. It began to round off the corners. Went to vice grips...still nothing. I can't believe this thing is this tight. I have taken many off of 98 and up and have had no problems.

Turns out the rubber o-ring doubled in size. Had to use an air chisel to break the solenoid housing and then use the air chisel to get the nut to break loose.

I'm about to replace my camshaft position sensor (2nd time code thrown in a week). Bentley says the torque for the Vanos solenoid is 22 ft-lbs (p. 117-16). This is a total newbie question, but do you use a 32mm torque adapter to tighten it back up, or just estimate the proper tightness?
