R12S: Valve check & adjust

Did the 6000 mile valve adjustment on my R12S yesterday. It's just like any other oilhead. I did try for the first time the HanSocket that Bob made me. Worked like a charm and I have perfect 8Nm torques on all my locknuts.

I did use a BMW TDC lock pin (because I have one). To install it, you need to remove the bracket for the rear brake fluid reservoir. Then it's a straight shot in.

Here are some pics for views. Some valves needed no adjustment at all, some were a hair loose. I have an appointment at my dealer next week to check TB sync and to change the final drive fluid again.

Nothing that the sprocket indicator can't do, Jim (for this application). I've used the pin (I made one) and the phillips head in the spark plug hole and the mark on the sprocket to find TDC for setting valves and they all provide the same results. My findings were confirmed in my mind when I watched a Master Tech at BMW Atlanta find tdc using the sprocket mark. If you think about it some, the area on the back side of the cam is pretty wide, so being within 5 degrees either way is good enough and the sprocket mark set at 3 or 9 o'clock is just fine.

I would not go out and buy a TDC lock pin. You don't need it. I scored this one used, I have it, so I use it. The indicators are good enough.

I don't know the precise cam timing, but the intake and exhaust valves are closed for about a full 360-degree crank rotation so trying to get to within even five-degrees is probably unwarranted precision. Doesn't hurt a thing, but probably unwarranted.

On shim-adjusted valves I do always set the engine at a precise TDC point for consistency; I don't want to risk the extra work of swapping a shim just because a borderline valve has gone out of spec due to my setting the engine as a slightly different spot and chasing the variations in the cam base circle. But on a BMW with screw/locknut adjusters, where adjusting is just a minute or two extra vs. checking, I don't worry about it and just get it close to TDC using a soda straw in the spark plug hole.
