I replaced those and they looked dry, but I'll inspect them again. It looks like the oil is leaking out of the plastic U-shaped air intake tube (and my air cleaner has a cyclonic air separator, so I doubt it's blow-by). There shouldn't be any leaking from this area because the cylindrical rubber gasket in the tube is fairly new, but the aluminum mounting surface of the front of the turbo is very worn and has a concave instead of a flat surface for the gasket.
