Stainless Steel Pipe VOD Rusting?

[1batt4u]

Hi all,

My S/S pipe in the VOD is rusting. Does that make sense? I bought the pipe from John Hervey. I just installed it 2 months ago. Car is under work. I checked it out today, it is rusted all over. It has rust spots all over. Why would that happen??

Cheap stainless with a very high carbon content. Or it is actually mild steel. I have replaced a number of those and ditch a number more years ago.

So you have the better ones now?

That pipe is totally optional. Its only purpose is to locate a barb on the backside of the engine to speed up assembly line manufacture. You can replace it with a length of hose no problem. One owner has been running a hose in place of that pipe for nearly a decade now (about 10,000 miles per year).

Are we talking about the heater return pipe?

Yes that pipe. Mine has rust spots all over, and it is a new part.

Some stainless will mildly rust hence the name stainless and not stainfree. You would hope that it would be just as nice looking as the day you installed it but depending on the environment it might begin to rust right away. Call John and ask if he will send you a new one. I bought one this year and installed it and if I'm lucky I will never see it again and it will not rust through or collect inside corrosion like the steel pipe did that was replace. Stainless will always last longer than steel, it will not rust through like mild steel will.

Hmmm... I'd be more concerned about what the inside looks like right now. I redid my valley last summer and the inside of my original was heavily corroded and build up had blocked most of the flow through.

Use a magnet to test if it is stainless. I bought one of those pipes from John but never installed it. I installed a hose to replace it.

So I used a magnet and the magnet sticks right on easily!

So what should I do, ask for refund?
