I just got my hands on a 2.3 HO manifold....
To me, this is like the holy grail of intake manny's for the 2.4.
Anyways.... it looks just like every other 2.3 manifold.
I'd like to clean it up, and shine, as well as smooth out the outside...
I started playing with some 120 grit on it, and it's slow but working good.
The problem, is the inside is a little gunked up.
It looks like the typical engine grease/oil mess, and I'd rather not have my engine suck a piece of this in, should a piece break off.
Any tips to clean the runners out real good?
Also, is it possible to smooth the inside out, possibly to a 100 grit smoothness, and with luck, a 300-600 grit smoothness?
Thanks in advance!
I know it's JUST a Cavalier, and I'm sorry if I hurt your ego.
well big pipe cleaner, or a wire brush might work for the inside. As far as sanding it i dont really know. For the outside just keep sanding and then when its really good polish it

I'll have to get my hands on a few different wire brushes and pipe cleaners....
Thanks man.
And the outside.. right now I used a little 100 grit, and it's smoothing out nicely...
I'm gonna just keep doing that until it shines up real nice... the aluminum seems to be easy to work with.

watch what you use on the inside you may very well ruin your " holy grail" . Aluminum
in takes sometimes have a clearcoat on the inside. This is used by the factory to help seal the casting and insure no vaccum leaks as aluminum is a poreus metal. By sticking a wire brush or even a pipe cleaner into it you could damage the clearcoat
there by creating a vaccum leak that will stump the best mechanics around. my recomondation would be to use either a throttle body cleaner that says its clearcoat safe or just plain old soap and water with a soft brissle brush.
Good luck.

Ahh good thing you posted....
Thanks for the tip man, I wouldn't have thought of that in a milion years...
Taking that into consideration, I'm thinking about some hot water + normal soap, while using something like a toilet brush (with nylon bristles) and I may even try to hook that up to my drill to get it done faster....
I'm just not sure if nylon bristles (hard or soft) can damage clearcoat....

couldnt you use a pressure washer? or would that cause some sort of corrosion?
I dont think that would hurt it you should be safe. I'm not saying it deff does but I always
say better safe then sorry. If that thing is as good as you say why take a chance on ruining it.
Good luck.

Why dont you buy a throttle body cleaner at an auto parts store!
I know its available and made to degrease them spotless without binding any mechanical parts.
