Hello single Mom....

These engines are renowned for rear main oil seal leaks...
and crankshaft position sensor which is just above the starter...
The CPS is located in the side of the block above the starter...

There is also a GM Service bulletin on porous block conditions on some of these engines...

GM BULLETIN #05-06--01-034L: 5.3L, 5.7L, 6.0L, 6.2L, 7.0L - Engine Oil Leak at Rear Cover Assembly Area (Engine Block Porosity RTV Repair Procedure) - (July 23, 2010)

DOCUMENT ID: 2506955

Hope this helps...
