the way you wrote it, its like it all happen suddenly, check your oil level next clean-up everything and start the car, put a piece of carton under the car so when it leaks you can see from where it came, or put the car on some jackstands and go under it with the car started so you can see from where it is leaking. simple things to do.

Well its probably that it didn't happen suddenly It's just now that I was under the car to see it checked the oil today and it was low not bad but low but now its flung all over the place and its on jack stands right now and there is a puddle starting right at the back of the motor and the tranny. So I have narrowed it down to being that. It's probably never been changed and there is 153k miles on it its time it needs to get changed. And throw a stall in it while the tranny is out

I'd definitely be checking the back of the intake manifold too. Although you don't have a lot of liquid up top, it could still be that. Liquid runs downhill...most of it will be lower, but you'll find evidence up higher. Usually a thin film and/or dusty grungy crap on it from oil attracting junk.

It isn't to hard to take it off right? I have the TB off and its just the open intake took the front few bolts off and then all the plugs and stuff that are in the way that bolt to the intake. That and the injectors I need a curtain tool to take these off?

The fuel rail pops off with the four bolts on top (leaving the injectors in the rail), then just swing it up and out of the way. You don't HAVE to remove the fuel lines, but it definitely makes life easier. You can get the GM tool for like $10 from any parts store (5/16" and 3/8" lines).
