how to remove oxidation from plenum
Any ideas on how to make my 14 year old intake plenum look new again? I just got done with rebuilding the engine. While I was there I put a new intake and runners on, painted the valve covers, etc. It all looks pretty good with the exception of the plenum. I'm not interested in polishing it, I want it to look stock. Thanks

I taped it up and sandblasted mine.It looked pretty good that way i thought.But i made the mistake of clearcoating over top of it to keep it clean.It didn't peel or anything just has a yellow tint to it. Just make sure to wash it it really good just in case anything got in there.If you decide to go that route.

I first cleaned it with arb cleaner thoroughly. Then I sand blasted it and later primed and painted it with the silver color used for the valve covers offered from ZIP. the plenum and runners look great with the same color as the valve covers. I was very happy with the results. Good luck :thumbs:

Actually,the bets result Ive found so far was having the machine shop boil the plenum in their hot tank or steam tank?I forget what they called it.It came out looking brand new and you could eat off it.
It will oxidize again later after some time down the road but for the most part,without painting or anything,was a great way to make it look new again.

Media/sand blasting. It gets rid of all those scuff marks that simple green can't touch.
In this pic, the distributor cover wasn't sandblasted, so you can see, there's a slight difference in appearance.

When I get around to taking mine all apart, I'm gonna have it all powdercoated black, to look like the factory B2K intakes.

Sandblast with glass bead.
Walnut shell media is good also.
Be VERY careful if you use mag wheel cleaner or any acid. All steel parts will oxidize (rust) when exposed to acid, even when rinsed with water.
For a quick clean up use a brass wire wheel in your drill. Don't get too agressive and use the lightest wire you can find.
I had mine dipped and boiled. Got the inside clean, but still had to sandblast the outside to get rid of all the oxide.
My personal opinion is not to use paint. Aluminum has a great look when it is not oxidized.
