ok so the chevy dealer said they fixed the oil leak and replaced the oil pan gasket----it has started leaking again, same place on the side of the engine in the rear where it attaches to a spacer plate and then the bell housing---------they have it torn apart again ----- been in the shop for a week

I've had the oil pan off an LB7. It's glued on with RTV/Silicone - no gasket. Not many (if any) gaskets are used on the aluminum crankcase, (part between the pan and the cylinder block). There might be a defect in the aluminum (crack, burr, hole, etc.) that is being missed. These engines are pretty oil tight.

Also, an oil leak source can sometimes be hard to positively identify. A leak farther up on the engine could appear to be originating at a lower portion of the engine.
