3.5L EcoBoost Snakeskin oil pan?

[mrtull]

I changed my oil today @ 1233 miles. Had the truck a month and no serious off road driving. So is it normal for a relatively new oil pan to look like it's a shedding snake? I don't normally do my oil changes so i have no frame of reference. Thanks in advance.

not to worry, that effect results from the casting process.

Agreed. Just something that happens when casting aluminum. Years back I remember seeing the external surfaces of cylinder heads on some Saturns and other GM's looking just like expanded styrofoam used in those cheap coolers you get at the grocery store.

Thank you for the affirmation, @jmh86325 and @Porpoise Hork
