Alright, I was installing my homemade discos tonight, and like a moron I didn't use wheel chocks--though the e-brake was on. I had a jackstand under the passenger side framerail, just behind the LCA mount, and a smallish jack with a block of wood under the axletube. I'm sure you see where this is going now. The car somehow slipped off the block/jack. Nothing looks broken/bent, but after I buttoned everything up and took it for a test drive to see how the new discos feel, I got back and there's a little splattering of oil on the pan. Very little, but my XJ's never leaked a drop of anything before. I feel badly asking this because it's my fault and because this really isn't too big a deal, but I want to know what I should be checking underneath. If anything, the block/jack slipped backwards possibly into the oil pan or I suppose it could've hit the tranny hard lines. I could see a fresh smudge on the pan about where they might have hit it, but that's it. Any ideas?
