Oxidation question

Hi All - I know aluminum oxidizes, and I've seen the posts saying don't fret, but I guess I'm looking for confirmation. Is this amount of oxidation any issue? It's a 2108 with only 4K miles. Thanks all, Jakester

That's normal. Climate/area of the country will make a difference in how fast that happens.

Spraying it with WD40 or similar product wil help.

What part of the country are you in?
In Texas that isn't normal but we don't have salty roads. Never use Simple Green on your aluminum motor or it will really be oxidized.

My engine has the same appearance as seen in the OP's photos. I think it is because they might store some of the engine components outside or it could be from sitting in an impound lot prior to delivery. My Challenger was built on Jan. 3, 2018, so I am sure it was subjected to winter weather before making it's trip to So Cal where I reside.

When aluminum corrodes, the surface appears as an unsightly dull gray to powdery white color. This is not harmful structurally. What many people do not know is that this aluminum oxide, a very hard material that actually protects the aluminum from further corrosion.

it depends on the climate you're in.

A friend here in NC "winters" his Scat Pack in South FL and its parked outside under a car cover.
- the aluminum engine front cover, water pump are oxidized.

My late father lived in SE GA (near the FL border) and anything aluminum really gets cosion / oxidation

I've noticed this is areas where roads are salted.

I lived in (very rainy) Oregon and my vehicles get driven year 'round - no oxidation. Even my now 18 year old 'Benz (all AL engine and magnesium cast parts) doesn't have oxidation.

If you're also in a coastal climate and parked outside - its likely to happen with all the ambient moisture in the air and the salt.

If SF, if you lived near the beaches - you need to use brass or stainless fasteners on everything on the exterior of a house. Otherwise, you'd see rust streaks running down light fixtures, siding, fences.
-eventually fasteners such as screws and bolts would shear off if you had to remove them to service something on the exterior.

Asian makes of cars that weren't garaged - you'd see the weak spots where the salt air / fog would start rust to develop.

Clean off with a small wire brush then then use Liquid Wrench L512 anti corrosion /anti rust spray . it will keep raw aluminum looking new for years . dries clear like it’s not even there

Awesome thanks everyone! I live where there is definitely a lot of salt on the roads in the winter. I might clean it and use anti-corrosion spray, but first a CAI and catch can.
