Too Cold for a Valve Adjustment?

I was planning to do a valve adjustment today, as it is the only day that my schedule will allow. The car has not been started for two days. I pushed it into the garage this morning, but the car has been outside and the current temperature is 26 degrees.

I understand that adjusting the valves with any heat in the engine is a big no-no, but is there an issue with low temperatures? I know that laying on the garage floor will be unpleasant and it will take forever for all the oil to drain, but other than that, can I get an accurate adjustment?

If you want to adjust valves and save the oil you can tilt the car.
I haven't seen posted the relationship between lash and ambient temp, there has to be a wide range of temperatures that would be encountered around the world that will produce an acceptable lash with 0.1mm feeler. Germany as a country tends to have temperatures on the low side compared to many. My guess you are fine at 26F.

I don't see any problem doing the actual adjustment other than the obvious unpleasantness, but if it were me I would've ran the engine to warm, drain the oil and then wait over night before tackling the adjustment. The problem is at that temperature, I'm not sure you will get all the old oil out that you should, no matter how long it drains. Cheers
