I have a 2013 Silverado 5.3. I changed my oil and I noticed that I had an oil leak right above the drain plug. It was dripping off of the two starter bolts. I looked around and I could not find where the leak was coming from. It’s going in the shop on the 3rd to have them look at it. The head gasket is dry. What do you think it could be.

Check your oil pressure switch. Should be at the back of the intake.

find another auto repair tech . smart mechanics use a dye in the engine oil UV .. then the leak will be found quickly.
you said the oil leak is at the starter motor so did he remove the starter motor check the CPS sensor ? possible the rear main seal could have a small leak ..
