Ah, I know this. I was just confused on what you said before. It was on a flat surface when I put it up and drained it

 

Yeah I thought that was maybe overly fundamental.

 

Thats about the stupidest advice ever, are you trying to get the guy killed??? Never crawl under a car that is on a jack, especially the crappy scissor jacks that come from the factory. If your just changing a tire or something a jack is fine, but if your under the car wrenching thats a totally different story.

Invest in some quality jack stands.

 

Or at the very least post and see if you have some F-Body locals in your area who might be able to help you out
