I was parked in a buddy of mines driveway and we noticed some oil on the ground and it was coming from my truck so while i was at work i pulled it in and there is oil residue on the right side below the head. I want to know how much it will cost to fix it. I have only had the truck for a month and i didn't get and extended warranty on it. If possible i want to know if i can fix it myself and what the parts would cost.
