Help Identifying Oil Leak 2008 4cyl

Is it common for the 2TR-FE to have an oil leak around the timing chain cover? After inspection, there looks to be oil on the bottom of my cover on my 2008 with 125,000 miles. Has anybody else experienced this?
Here's a picture...it's from the bottom (removed skid plate) looking up. You can see the oil pan at the bottom...thanks for any input!

 

Sorry I'm a bit confused on the orientation

 

I'm confused about the orientation, too...but to answer your question, I've had an oil leak there, also. But we live in a very rural area and the little 2.7 travels about 50% of its total mileage down dirt or caliche (or no) roads and when it rains, muddy roads in and out of pastures. 4 wheel drive is a necessity for any pickup we own. Your leak appears to be the common problem with these engines of a blown or seeping front crankshaft oil seal in the timing chain cover. If I remember right, you've got to remove the crankshaft pulley and then the seal you need to replace is accessible. The repair's not that difficult. I used the Toyota OE seal, although parts stores can get name brand aftermarket seals. While you're replacing the seal, check your water pump seep hole. Mine was seeping a bit, so I also changed the water pump at the same time. Because the pickup had 90,000 miles on it, I also changed the coolant and used Toyota pink. There wasn't even a hint of corrosion or discoloration on the original anti-freeze The super long life Toyota Pink must be good stuff.

 

Great info! Thanks so much...I'll look into the front seal
