So, last night, it got to about -33 Celsius. My truck officially hated life. Well after 12 attempted jumps, the block heater being plugged in for an hour, and a new battery, she finally started. but my buddy pointed out that i was leaking some oil. I thought the rear main had blown completely, but its more near the middle of the engine on the passenger side. does that maybe sound like the seal on the oil filter? because it only leaks when the motor is running. thoughts??
