So its 10 - 15 below for about a week now. My 1999 is in the garage at night and sets out all day. Let truck warm up for 10 minutes as it was on a timer and was plugged in for 3 hrs. Drove home tonight pulled in garage got out could smell oil on exhaust. looked underneath sure enough oil dripping down. Go under truck oil everywhere look under hood oil behind and rearward of power steering pump but its not power steering fluid I double checked. It is not squirting out any place i can see. Also continues to drip for quite a while after being shut down. Not very much easy access to the block on this side. I still have oil pressure by the gauge. Please give me your best ideas. thanks for any help.
