Rust under the hood normal?

[14SLTZ71]

My rust is better than your rust !

Mine is not only better then yours, it has a mind of its own. It's flaking off because it's sick and tired of all this vibration. The undercoat said it will follow the rust anywhere.

Yeah, its bad when the rust is abandoning ship. Maybe the rust will run to the Ram's.

[14SLTZ71]

Maybe I can get the truck to vibrate all of the rust off, get a new coat of undercoating and then get the vibration fixed and then it will be like a brand new truck. Oh wait, it is a brand new truck and there's no fix for the vibration or the delayed throttle response, or the goofy shifting, or the brakes dragging, so I guess it's SOL.

Edit: oh, that's right. There's nothing wrong with this truck. It's all normal and operating as designed, within the normal characteristics of the truck as designed by the engineers, or of course it can't be duplicated consistently enough to diagnose so it's "normal". Ding ding ding

Whats bad is I am working on getting into my THIRD 2014. And the one I picked out is starting to rust already. I figure that is the one thing I could live with. My main concern was checking

for vibration. All the drama is getting old. I kinda feel like fool for even wanting another one.

How does that definition of insanity go?

I agree. Edit: Lol

LMAO! How could we ever forget that? Is that REALLY how they say it in TN? Cause we say it a whole lot different up here in MI.

 

That is a CLASSIC!

The exhaust manifold were rusty when I first took it home with 9 miles on it. Haven't noticed anything else lately. What I figure it's just morning dew that collects under there.

 

The way your title says I was assuming the hood itself was rusty on the bottom and I was confused because the hood is aluminum.

back on topic OP mine has rust in the exact spots as well no worries

Yes, and this reply of yours justifies why GM is selling new unpainted differential covers with rust spots on them already in the parts bag. An iron casting , if unpainted will rust of course and other than being visually unappealing, the rust will not hurt anything. But not painting a stamped sheet metal cover that will be visible from behind the truck when installed?

 

In case you do not know, marine cast iron water cooled manifolds are painted after they are cast and machined, and they look a lot better when installed than they would if they were bare metal and got all rusty. So do not give me that crap about "it will rust if it has iron content." Yes I know. Especially when the company is too cheap to have these parts painted.

I get what you are saying, but now you are comparing different application marine and road vehicles, which fresh water boats are never subject to salt, and marine engines typically never get the use that vehicles on roads do.

 

Im not saying your crazy, but your still trolling. With vehicle manufactures its pick and chose, every manufacture has its downfalls, if a manufactures proofed everything against everything vehicles would cost more than most of us could afford. As I said before metal with iron content will rust anything else will corrode to a certain extent, some worse than others. If you live in an area where rust is an issue i suggest undercoating or painting.

I use my boat in salt water, and so do thousands of other boaters here on Florida Atlantic coast. The marine environment that boats see here is brutal. Even small stainless steel fittings corrode and break in sea water after some time, as i experienced on my jet ski reverse cable.

Again, that has what to do with the original subject? Nothing. Your posts are no more useful than any other form of spam. A cast iron exhaust manifold is rusting...that must mean the 2014 GM's suck.... Grass is green too, does that also mean 2014 GM's suck? Because they're made in China?

How about this genius: A cast iron exhaust manifold is rusty because they are too cheap to paint it, if they painted it when made with high temperature resistant paint after it was made, it would not be rusty for a long time.
