Default Where is this oil coming from???

First off... When my vet was in blocks when i got it i noticed a little oil in the same spot.. Cleaned it up and nothing until now.. month later maybe.. The reason the oil is so long. there was a long piece of grass that the oil formed around..

Ooh that's a good one.

First I would jack up the car, get under it, and look inside that side of the frame. See if there is any oil INSIDE that frame rail. Maybe it's entering the frame further up, and while driving it moved backwards, and drips out to the floor.

Check the whole frame all the way up to the front.

The only fluids at the back would be brake fluid, gasoline, or shock absorber oil. Depending on the shock...that may be the case...but it's not int he right place.

Did you happen to smell the fluid? That's usually the best way to finger a fluid aside from looks. VERY bad and dirty brake fluid can sometimes look like engine oil but them still smell different.

It does look like engine oil. You're also right, and nothing else seems to be leaking. That cross member LOOKS like it's saturated...but how it got that way is the mystery.

any chance it could be a small gas leak up above picking up the softened undercoating from the frame, tank or crossmember and dripping on the floor.

Hmmmm - small gas tank leak coming from the top of the tank, picking up gunk running down side of tank and dripping on floor. Maybe check gasket around input to gas tank.
