I was changing the oil on our 2010 this weekend and I noticed a lot of build up on the front, passenger side of the block as well as below on the front skid plate and rear one below the engine. I thought it was an oil leak at first but the dipstick did not show any loss of oil and there is fluid slung on the lower area of the passenger cylinder head. My guess is a shaft seal leak on the PS pump. Has anyone had this happen on their 5th gen?

I've found some low mile used pumps but it looks buried in the accessory setup. I can change the pump in 20 minutes on my 4.7L Dakota but this looks like a frustrating job. The PS reservoir was only down about 1/8" and was barely below the "hot min" line and was recently driven. I don't know if the expense and time (read frustration) is worth it for such a minor leak. I don't see any drips to completely diagnose this issue either. Thoughts?
