I was rotating tires today and looked inside the passenger wheel well and saw this leak. This is near the rear of the engine on the passenger side.




I'm pretty sure it's a valve cover gasket leak, but could it be a cam tower leak as well?
Any input would be greatly appreciated.

A few more pics if it helps.

Looks like cam tower leak. An big job to reseal, I would not worry about it unless oil starts dripping on exhaust manifold.

I would clean up with some brake cleaner if you want to be positive

You could use some baby powder as well
