So a friend bought a "box-O-parts" engine kit 3 years ago and thought to preserve the parts in Phillips preservative oil. He coated the parts in the Phillps product, placed them in a sealed plastic container along with some desiccant and left them until recently. In the pic below you can see what the cam now looks like. This is not rust, but some kind of goo that formed only in locations where the part was submerged in the Phillips product.
It does clean up with various solvents he's been experimenting with and lots of elbow grease.
He called Phillips and was able to talk to tech support who told him the product is not meant for long term storage, longer than a year evidently (contrary to the product tech sheet) and that the goo was the result of fatty acids in the oil reacting with air/moisture. He apologized for the poor result, and no damage was done other than loss of time. But I have to wonder what this stuff would look like in an assembled engine after a year or three.
Anyone ever seen this?
