Question about some odd rust

sounds odd from your description! i think this is a perfect opportunity to work on your pic posting skills---- because i what to see this! maybe i'm just still half asleep yet reading this, but sounds weird

If you can't do it with you computer Don, you can email me the pictures, and I will post them for you.

Microsoft has finally screwed all 3 computers so this is the best I can do to get a picture up. The shine is lost but the rust or corrosion can still be seen. The truck was Zbarted and I wonder if that is what caused this because they just sprayed everything. I couldn't get anything with my camera that wasn't a blur from the PS pump. This is an exhaust manifold.

FYI, Helm said they are doing whatever they can to keep WIN 10 away from IDS.

Yes, it's an exhaust manifold. Scale rust? It could be but I always thought of scale rust as being like fish scales where the metal erodes away in layers. I wish I could get a better picture but if the picture is taken too far away you can't make it out. Too close and it blurs.

This is all solid and hard and there is no scaling to be seen. It's shiney which can't be seen well in the picture but you can see at the bend the rust\corrosion stops and the manifold changes color to the typical orange rust color and leaves the rust dust on your hands. Where the pitted, barnacle look is at nothing is left on my hands when handling. It's hard, smooth and clean (looking). It's on a lot of components which I didn't start to get a good look at until I pulled the PS pump.

I'm thinking it was caused by something that got on the engine and reacted with heat but it's nothing like anything I've seen before. It's why I wondered about the Ziebart treatment which was sprayed on without much thought to how much or what it got on. The sticky, tar like stuff is on everything and can't be avoided.

Whatever the cause it's more detrimental than the typical rust.

I do a lot of work at a site where they spray the roads with a salt mixture that has an additive that makes the salt stick to the roads. It also makes the salt stick to your car. I think it's a beet juice extract...

"Beet juice" is a new one to me and I'd tend to agree with you except this is only where there is a lot of heat. That's something I couldn't originally see until I started taking the truck apart and did some cleaning. What rust there is to areas like the springs and chassis is typical unlike this. The one thing that heat hasn't effected is the SS exhaust and the aluminum engine components. Although it's not limited to cast parts that's where it's the worst.

I'm convinced this has something to do with the Ziebart or something else that got sprayed under the hood at some time. Like John adds, "chemical." It's odd how it seems to have encased the parts.

Stanman, I lived most of my life in the rustbelt and this isn't the typical salt effect. I've never heard of any salt additives used here to explain it. The trucks entire life has been here also so it's not an imported effect.

what?????

Right through the block. When I was letting my buddy work on the truck here we knew the problem was either a cracked block or blown head gasket. We hoped for the head gasket but I'd guess now it was the block. Obviously something extremely unusual happened. It went through something, somewhere or something intentionally malicious was done to the vehicle.

Never seen a block rust thru before.
