ATP AT-205 is also a reliable oil stop.

Doesn't surprise me. The ST used to be identical to AC Delco in every way except color. I used them until they switched to something that looked lower-end, about the same time AC Delco switched to their e-core. I'll pop open a ST box next time I'm at Walmart. Thanks for the input.

I use an amsoil eao64 in mine with m1 ESP 0w30. It had better HTHS ratings and better viscosity characteristics than the 0w30 fuel economy stuff IMO.

So after many wipe downs and relooks, the top one seems to be the valley pan gasket but still not 100% sure. The bottom leak looks like the oil cooler bypass block off, which I replaced exactly 1 year ago. Looks like it's dripping down and the wind is taking it to both sides from there. Easy fix on bottom but the top will be a later date it it leaks worse.

Any new update? Did you fix/replace the oil cooler bypass? I have the same exact leak spots, I was told to
change the o ring on the drivers side where the hoses connect. I'll try replacing that on my next oil change and see what that does.

So I have cleaned and wiped many times, I have two leaks. The drivers side seems to be leaking from the aft lower head to block, which I am going to try tightening the bolt a bit. The passenger side is above the starter, which I will look into this weekend but I think it's the crankshaft position sensor seal. Does anyone know if I can only purchase the seal by itself? I've looked everywhere except the dealer.

Thanks for the heads up but, I did clean everything once again and watched while it was running and found it leaking at the rear of the oil pan above the starter. There's no oil around the rear main seal which is really good, but the pan will have to removed.
