Stainless steel exhaust elbow

I have my Volvo elbow off this winter, which is 3 or 4 years old, only to access my turbocharger. All these OEM cast iron pieces of junk corrode quickly. Itís amazing how much material is flaking off inside, over such a short window. It was still very serviceable, with a cleaning, but I decided to buy a 316 Stainless aftermarket elbow, from HDI. Itís already clear itís a superior product, since it doesnít have all the plugs in it for the various other configurations the OEM part might be used in. Iíve heard they should last a lifetime. Even if it didnít, it was less than half the cost of OEM, so I canít really lose.

Would you paint it? I almost did it out of habit, but then wondered why I would paint stainless and introduce the potential for crevice corrosion inside scrapes, etc. The stainless isnít polished, but I also wondered if the engine paint would adhere properly.

Don't paint it. Paint does nothing good for stainless steel. You might as well leave the bling showing.

LOL. Thanks. Glad I paused. Almost happened on autopilot, as Iíve never had a SS part on an engine before.

Doubt Iíll get much curbside bling credit for this matted hunk of steel in the bilges.

Re: Stainless steel exhaust elbow

I agree - painting stainless is not a good idea. Any peeling/delaminating paint would create a low oxygen environment, which would allow corrosion of the stainless.

Half the cost of cast iron and a chick magnet. I never realized the extent of the value.
