I have never seen anyone mention this, so I'll assume no one else has seen this.

I popped the bonnet and I saw rust on the block. I'm not very technical when it comes to cars, so I may be describing this incorrectly. But I do know what rust looks like :smile:.

How bad is this, and what can I do to get rid of it?

Ideas, thoughts...

Is it on the cast Iron part? The Block, this would be normal, you could have the Engine removed dismantled and painted, but some people would think you are just a little ****

 

rust on the engine block? It's iron, so DUH!
There is no need to worry, it will take about 100 years before the block rusts through (seriously!)

Cheers,

Once a thin layer of rusts forms on a bit of iron the rust will probably prevent any extra rust for forming.

The layer of rust keeps any more iron from being exposted to the air and so it can't rust.

This works as long as the rust is not distrubed.

 

Thank you all for your input especially the "Duh Alert" from Ryephlie . I'm not **** so I won't be dismantling anything in the future.

Thanks again.

Not trying to be rude, but... Chemistry 101 would refute your theory. If it were true those little tiny rust spots on old cars would never get any bigger and we all know that's not true. Personally, I'd point out the engine block rust to the dealer. It probably has a defect in the anti-corrosion coating.

 

It only works for solid parts like axels and driveshafts. Sheet metal is too thin and rust can form on both sides.

Look at the axel or driveshaft on any older vehicle. They are almost always covered with a thin layer or rust but never fall apart. Chrysler usualy ships these parts type of parts uncoated to save money because the thin layer of rust ends up protecting them.

 

The rust (oxidation) is normal on iron blocks. In fact, if you crawl up under the car you may see more parts that are oxidized. You can clean them and paint them, but what for? You can't see them and they really do no harm in our lifetime.

 

As a matter of fact, the USX tower (US Steel Tower) in downtown Pittsburgh was designed using this principal! The exterior of the building is a certain type of steel for the the specific application. It was never painted and has developed a light coating of rust that gives it a very distinct look and protects the rest of the metal!
