Need help finding oil leak…..

Young Guy said:

I have an ‘07 Tahoe with an oil leak. I replaced my oil pan, but there’s one more leak. After investigating, I find that it’s leaking above the starter. I wasn’t in a position to remove the starter, so that’s as much as I know.

Based on this information can anyone give me a possible diagnosis, before I take it to a mechanic.

Any info would be greatly appreciated.

Check the dipstick tube o-ring, where it plugs into the block. Also, does your oil pan have the old-style oil level sensor threaded through the side of the oil pan, below the dipstick? Like this:
