I think it was Ted who theorized, at one point, that my cooling system may be "too efficient." I went for a drive over the weekend when ambient temperatures were in the mid-to-upper-40's. Despite driving 25 miles in about 30 minutes it felt like the car never really warmed up. My cruising oil temperatures would drop below 140 degrees (sensor below oil filter). It wasn't until idling in the driveway for ten minutes afterward that I got the temperature up to 170. Usually my driving oil temperatures are between 150-170 degrees on more temperate days but I don't think I've seen more than 175.

I also found out my catch can line has been plugged all along. It's fixed now, and I didn't notice any immediate differences in how the car drives, but I have no idea what can of effects that could cause.
