Clean Intake Manifold


Recommended Posts

I'm having to remove my intake and exhaust manifolds. Long story that I won't bore you with. Since I have the intake off, what is the best method of cleaning it and protecting it so that it will be easy to maintain in a clean condition? I have a few ideas, but I wanted the advice of all you experts out there. '71 240Z Thanks

have it bead blasted or walnut shell blasted then have it clear powder coated. Have them use a semi-gloss clear so it doesn't look too shiney and it will be easier to clean off later. You need to remove all the bolts and studs before you have it done though.

If you want the added benefit of reducing heat transfer you might consider a metallic ceramic coating, which is available in a variety of colors and textures. Not much more costly than powdercoating either. Just like powdercoating, you will have to remove all studs, but temporarily install bolts to protect the threads from being coated. They prefer to do the cleaning and prep work.

That reminds me, if anyone is planning on getting some ceramic coating done I'll pass this along. You would have to send more than just intakes though to spend the required $200.00, to use the coupon.

You can get the single stage reflective chrome powder coat from Eastwood at the following url:

its not as good as it seems. It discolors if you get any type of engine degreaser or other solvents on it, just like the 2 stage chrome. I did a couple of motorcycle foot pegs for a guy and he brought them back a week later after he got degreaser on them, and they had turned gray.

Also, on my 240, I did the accelerator linkage, right on the firewall part and left it on when I pressure washed the engine compartment. Zep Industrial Purple turned it gray too.

2003z,

Can you recommend another product that will hold up to the underhood enviroment most engines will see? (I.e. - Name brand, Item #, Vendor) I think he was kind of thinking along the lines of powder coating....

you can use that single stage chrome, but I would put a clearcoat on over it. Since its the same price and both really need a clearcoat, I use their regular reflective chrome, because it shoots out smoother from the gun and doesn't get silver veins if applied a little too heavily.

2003z,

How about JetHot? I know that it is pretty much used on headers...etc...etc. How about the intake and heat shield as well? Would probably be a little bit of overkill...but from what I've seen of it...it should hold up quite well under the hood...

I think that would be an awesome solution. I have an old hooker header on mine that was extremely rusty. I got it ceramic coated in black and it looks great. They first do regular ceramic (jet hot) inside and out, then put a black ceramic topcoat on it. Haven't got the engine running yet though.
