I need some advice. I live in Phoenix, AZ and it has been super cold here over the last three days. I usually drive my truck about 3 miles a day too and from work. This afternoon, however, I drove my car about a mile and it started to rev a little funky as i was pulling in to my destination, as I was slowly backing up, the idling would rev up and down and almost jerked around the car ever so slightly.
I popped the hood, check the coolant (seemed slightly lower than normal but remember it has been super cold here) and then I checked the dipstick. There was a white, almost milky residue or hue to it. The oil was changed back in October. I turned the car back on and it was making ever so slight idling the variations, then the check engine light briefly flashed... so I shut everything off.
Any ideas whats wrong here? I read something about it being condensation becaue I don't run the car enough in these very cold temperatures. could I have a blow head gasket?? Please help, Im afraid to start it again and don't want to damage the engine. Thanks.
Truck: 2001 Tundra 4.7V8 with roughly 170k Miles. (barely broken in..)
