This is the first time I've ever posted here, but I've browsed this site before for advice and what not.
This weekend, I noticed a slight oil leak. I don't know much about cars, but I studied mechanical engineering in college and I generally can figure out how things work and what the problem is.
I climbed under the truck, and right above the leak there was a bolt that had oil seeping around the sides. It is almost directly under the engine and the bolt is perpendicular to the ground. I need help in identifying what this this. Do any of you know ? Do any of you have access to a drawing that identifies the basic components under the truck ?
I've got a really crappy picture I took with my phone that I can post, but figured I'd see what you guys think first.
