2010 ES350 Oil Seepage
Hello, i was doing an oil change today and saw some oil seepage on what seems to be behind the power steering pulley. You can see it above when working from underneath above the oil pan to the right. It looks like engine oil but maybe it’s power steering fluid. Any thoughts?
Here’s the picture from underneath.

I think it is driveshaft grease. Your deiveshaft boot is leaking.

Is the PS fluid level low? Probably not. Looks similar to oil seepage in our 07 ES350, and it is the common timing cover oil seepage. Seepage never leaked to the ground. I just clean it up every oil change. Also went to the slightly thicker 10w/30 oil to help reduce the seepage. Have been using that weight oil, full synthetic, for almost 100K with no noticeable issues.

Mine had a more clean vertical line of grease, so it was clear it was splatter in all directions. I ended up cleaning it off with a degreaser and monitoring. The splatter hasn't come back yet, so I think it happened when I was accelerating a bit too aggressively.

I was thinking the same thing - CV axle boots. I found some splatter around the power steering pump similar to yours when I was doing a fluid replacement. Notice how in your photo the grease/oil made it up on the firewall near the brake lines.
