When we arrived at the site this morning, Omelan noticed that there was a lot of oil on the ground below our north generator. After switching to the other one, we investigated as well we could. The dipstick showed that the oil level was very low and we concluded that we have a major leak — about four gallons have leaked in only a few days. The curious thing was that we could find no obvious places where the leak might be. At any rate, that kept us busy for the whole morning and part of the afternoon. I think that we will need to get a technician in to figure out what is wrong.
We had a longer lunch break than usual because our new neighbours from up the road came to visit us. We had lunch together, and then we gave them the grand tour of our instrument. They had come up using the ALMA road and had been given a large, flexible "ALMA" magnet which was stuck to the hood of their truck.
It wasn't until later in the afternoon that we could work on the grease sprayer system. The grease was still pretty soupy, so we left the can as it was. As for the malfunctioning sprayer, we discovered that its airflow is much less than the other three. We realised that we would have to disassemble it to make any progress and by this time we only had an hour of daylight left, so we have postponed it until to-morrow. Thus we arrived back in town having been busy the whole day, but with little really accomplished on the mountain.
Dinner this evening was new: some kind of curried chicken with a good dish of rice.
