I need to replace my manifold, got one off ebay, for some reason its black. What would be a good way to clean it (Inside and out what products to use) w/o f*cking it up at all. Also if I decide to paint it, what kind of paint and what do I need to block off so I dont paint something that shouldnt be painted.

 

youd think in almost ten years someone would have an answer for you

 

hahahahahahahahahah

 

 

I have never seen a board where so many old threds are always poping up. I guess lack of new topics will cause that LOL!

 

Since my engine bay is getting painted in the future, I was thinking about using this durable, made for aluminum product for painting the plenum and runners. Thoughts?

just to add to this thread im currently on a project where i took my injectors off for replacement. Well it turned into a manifold plenum runners new egr mat sensor and water pump neck and polish all parts since i have the upper part of my engine off then i plan to powder coat clear for a lasting finish. Do it right do it once right? Well im polishing now so im 1/4 way thru......

 

majobis... youd be surprised how inexpensive powder coating is...... given its a bit more than cans but less than a paint shot.... it depends is you plan to go back to the same spot you painted and see the ugly flakes comming off and to top it off layering that... i really recommend powder...

 

Posting this for posterity

had my intake manifold off so I figured I’d clean it up and make it look nice.

picture of manifold as removed:



Had it baked to remove the oils and then glass bead blasted. It came out looking like new.


from there I was thinking to either paint it or apply a clear coat to it. Powder coating crossed my mind too, but from what I heard it insulates the manifold and retains heat. Probably negligible, I went with the paint since it was cheaper.
Ended up using Eastwood 2k high temp ceramic paint. It’s rated for 650F with no baking required.

first time doing something like this. And I’m happy with how it came out. Also did a water pump with the same paint and turned out nice too.

 

much easier to have it powder coated.
you drop the part off nasty and dirty and pick it up whatever color you want.
easiest $95 youll ever spend
