Hi guys, I got a Tahoe 2007 5.3 LS Flex for restoration from the auction and it's a first day. So far, I got this crazy hole in the oil pan (should be an oil pan).. And some strange debris that I found under the engine bay after I moved the truck. Car actually drives and doesn't sound crazy (4 cyl, I was afraid to turn into 8) so it shouldn't be crankshaft or whatever. I hope. Will try to remove whatever is left of the oil pan and look further.
