A little concerned about oil flow - I ran the '41 9N about a half hour yesterday, quite a bit of time at half throttle or so. It was about 38 degrees outside. I was showing 24 lbs of oil pressure on the new gauge and a couple drops came out of the governor as usual (I have more work to do here). So I have pressure and apparently have oil flow. After shutting it off, I noticed the oil filter housing was only warm. I pulled the dipstick and the oil was just barely warm. All external oil lines are clear and filter housing torn down and cleaned up as part of the restoration. Pump gears looked to be in good shape when the pan was off over the summer. Does the oil just not get hot in these engines? As always - thanks!
