So before i drop my oil a couple of questions, new valve has arrived the f102 without the adapter, do i definatley use the fibre washer that comes with it or use a regular copper washer? and does anyone know the torque setting to install it safely?thanks.
I used a copper washer (I use new ones every time) but when I had the older system I used the fibre washer between the adapter and the valve. I never had any leaks on either so your gut is your guide. I set the ole' torque wrench to 20 ft/lbs and then gave it a little nudge farther (probably 22/23) since it just didn't "feel" quite right at 20. Again, no leaks or threads stripped after 5 changes, so I must be doing something right.
Oh, and I verifed the depth on the adapter-less model against the stock hex plug and the thread depth is identical, so there's an sound reason to use the copper gasket (slightly thicker than fibre and has the exact same penetration into the pan as stock). I wouldn't think that cutting it down to 2 threads would do anything other than put a lot of strain on those two threads. After all, it's the threads that hold things tight and if you change the surface area, your nominal torque needed is altered as well.
P.S. if you're super paranoid about exposure, the nipple on the -n models DOES screw off. I accidentally unscrewed the wrong part when I was removing my original. You can keep that detached while it's closed, I'd assume, and reduce under-pan exposure.
