Default possible engine leak?

I decided to check my engine's oil and do an oil change. I decided to also check out how my zipties were holding up too lol. then i noticed this...


this is right next to the oil pan




heres a farther shot... Not sure where the leak is coming from...

Any idea guys?

You can grab a I believe a 10mm and check to see if all the oil pan bolts are snug. Then spray everything down with carb cleaner or degreaser. Then I would check it in a week or so

hmmm it does kind of leak around but this is where the majority of the oil is coming from... I'll take another pic next time, I'm not entirely sure what that thing is next to the pan is could be engine mount. but its leaking from the top which is a guess. plus that sealing looks a bit off as if i had engine work done on it... which has never been done before unless the recalls had to get into the engine.

look around the timing cover area which is on the passenger side of the engine. I usually look up through the oil filter access panel once I remove it. You can see it pretty good from under the car with a flashlight. also check valve cover gaskets. If you had the cam recall, they should have replaced valve cover gaskets with that.

that was near my filter which is on the driver side... could be different I'm not exactly which recall i did but the most recent one hasn't been done yet... i checked the dip stick and it still at a good level... curious question... i drove 5000 miles and my oil still a decent, should i still change it or the synthetic for mobil 5W-30's are just really good? I drive my car pretty hard too :O
