Trying to reinstall the distributor body back into engine and it doesn't want to go past the new 'O' ring.
Every thing lines up to all the markings I have made before removing the distributor and the gears feel like they line up inside the engine, but it won't seat because of the seal. It goes as far as the seal.
The p/n is 91160210201 and it fits snug, just in case some one want to know. Engine is a RS.
Any tricks to get it to seat?

hi BC ..very easy just do not use WD40..any lubricant on the o ring will do .Use a little-litle force and it will slide into it..

Used VR1 very liberally. Just does not want to move past the seal. I twist and push using alot of weight behind it, but no go.

The old one was orange and the new one is black.

hi..well i did have similar problem back couple of years ago....I suggest to you get the green o ring...btw the old one was orange;-)
and one more thing..use if you have the old Bosch grease or the the new Sachs grease..

No Bosch grease. Wouldn't plain old VR1 oil do the job?

VR1 is Valvoline Racing Oil recommended here for the 911.
The 'O' is from the Porsche dealer so I don't think it is old. Anyway my Porsche mechanic said that is the ring they sent.
His tip was to take the rotor off and place of block over the shaft and hit it a few times. That indeed worked, so I am guessing it might last even longer than the 'green one' because it is much tighter.

You need to put grease on it. Get it started, then take a long thick screwdriver and a mallet and tap it in using the bracket to strike on. Gentle taps.....it will get it past the o ring.
