Default Oil Leak Help

My 2007 Monte sat covered in the garage all winter. I moved it out of the garage the other day and saw a small puddle of engine oil forward between the radiator & engine dead center of the car on the floor.

I crawled underneath the car & for the life of me I couldn't see where it would be coming from.

The car was started a few times over the winter and never moved. So I don't know if the leak is only when running or sitting.

Your help would be appreciated :-)

Well, you have a ss with the 5.3? I know that the 3.5 and 3.9 V6s have issues with the oil filter adapter gasket. It looks like its leaking from a loose oil filter, but really its the gasket thats between the block and the part you put the oil filter on. That is really the only leak I could see it coming from the front of the engine if its not a topend gasket leaking. Oil pan too obviously. I changed three oil filter adapter gaskets on 2 G6 and one Impala.

I had the eact same problem that bigmo421 referenced with my 2006 Monte 3.5L. The gasket where the oil filter mounts went bad. I wasn't too bad to have fixed by a local mechanic. Be sure to replace the oil pressure sensor when/if you get it done. It only costs another $20.00.
Good Luck,
