When I first got my '82 SC a few months ago, I asked for some engine cleaning advice from a co-worker who has a '90 Lotus Esprit. He said spray it all down with straight Simple Green, let it sit for a few minutes, and rinse it off. That's what I did. Since then I have aggressively gone at this particular section of the block with some Simple Green and a scrubber pad from my kitchen. This whole time the car is just siting in my heated garage, as I live in MN. I have started three times. That's it.
Now, I am noticing a small oil leak. The car could have had it before, but when I had a PPI done they said it was not leaking anything. I'm worried that I may have caused this. In the photo below you can see the leak, it's hard to tell where the oil is coming from. I have spent the last while looking around on Pelican and the internet to find out if Simple Green is a bad idea. I have found some people swear by it, some people don't like it, but no one who says that it will instantly make your motor leak oil. Are the incidents related? I am just freaking out? Either way is there anything I can do about the leak short of taking the motor out? How serious of a leak would you call this?

This is at the very front end of the crank case.

Same spot, different angle.

Back a little further.

The right bank, things look pretty clean.

This is on the front end of the left bank. This seems to produce a second, but much smaller drip

The fresh oil is about 5 days worth. That's about the size of a CD-ROM.
