Just a quick post to say -10F weather sucks (with windchill reported to feel like -40F)...
This weeks cold snap means I plug my car in at night so the morning start is pretty normal, but 9 hours parked outside at work resulted in last night when I started it up, it only took about 4 seconds to fire up (good battery) but abnormal loud sounds ranged from;
1st; Screaching metallic whirring sound, my first thought was an oil starved turbo
or power steering pump/ac pump.
2nd; kind of a wheezing whistling noise...air seeping in from contracted hoses to the intake?
I let it idle about 5 minutes before even pulling away or going over 1,000rpm, but could imagine the wear and tear going on...
The whole drive home (30 minutes) was done with moderate driving, as the car just didn't feel like it should but after the first couple of minutes driving most of the noises went away.
I run a 5w30 semi-synth at the car doesn't lose much oil at all between changes, but man, it's cold outside!
