Ok I, like many of you mkiii owners had oxidation on my throttle body, and decided to take it off. There are a couple of things to stay away from and a couple of things that work really well.

My throttle body BEFORE




Don't

Dont use any type of Degreaser, or if you do use sparingly.

The first thing I did was let the throttle body soak overnight in a degreasing solution


BAD IDEA!!!

when i removed the TB from the solution some type of chemical reation occured and I had black soot all over the place.

I then hosed it down and put in carb cleaner, and that didnt remove soute.

Then I took it to a sanding wheel and tht helped, but the TB is to intricate to go at it w/ tht... notice the soot on my gloves


DO
After this attemp i decided to use a sand blaster to get everything nice and ready to prep



after sand blasting I applied 3 coats of aluminum colored engine paint , then 3 coats of clear coat.

Here is my final product





Havent put back on car, everything is still in pieces, but when they go back together I wont be ashamed to lift my hood.

I dont think Im going to paint this one aluminum, just going to apply clear coat.... unfortunately I work all weekend so Im screwed..until Tues.

Corrosion has nevr been an issue for me. Perhaps my toothbrush, silicone spray, blue paper towel regimen is not a widely accepted underhood cleaning practice, LOL. Your final result looks great, but remember- it's easier to keep it clean, than it is to get something cruddy, clean again.

Anyway, it looks like your TB coolant lines went to shi+. You live in FL, so you don't need that part anyway:


Heh, looks pretty good. Too bad it's the bottom, LOL.


Take care.

Its true if you keep it clean all the time you wont have to do what I did, but unfortunately i bought the car soon after its 16th birhday, ao I had no choice ;) yours looks great... i assure you mine wont be like the before pic as long as I have my hands on it.

For sake of not starting a new thread.... you may also use this technique for cleaning heat shields... I used a little detergent to break off the big chunks, and carb-cleaner with some steel wool to shine it up... and it makes a big difference when you're done.

:) I love what you have done to your tb.

As far as I've ever learnt, sand blasting parts of the intake is a :nono:

It's virtually impossible to ensure you've gotten all of the sand lodged in the throttle body/intake plenum out. It will eventually dis-lodge and make it's way down the intake track into your engine, into the oil and chewing up your bottom end bearings.

They invented bead blasting for parts like this, IMHO! :cool:

I have my engine out...glad I found this thread. My heat shields look sweet now, debating painting em.

My intakes in worse shape than the one shown above. How would you clean the inside of the intake without sandblasting or beadblasting?

Get it ceramic coated!

Can the throttle body be ceramic coated?

I'm basically getting my whole engine bay done in ceramic coating and silver clear powdercoating so it would be nice to spruce up the old tb!

Thanks

Jason (this ones for you Jared) heh :D

I used kitchen cleaner that had bleach added, and that just took off grease from the intake manifold, thermostat housing, throttle body, turbocharger, ignitor pack without breaking a sweat. You simply spray a few shots at it, use a brush for a quick scrub, and then rinse with water or a damp cloth.

use B-12 chemtool.. it works like a miracle!!

leave it in the bucket for about an hour or two. then presto its all shiny clean.. sometimes u have to wipe off. use carb cleaner or brake cleaner to spray some stubborn residues stuck in the corners. it works damn good!! less work cleaning parts up!

while using that. DO NOT put in with any parts that has electronic parts. or plastic parts cuz it will melt!!

i notice the TPS was removed.. was it difficult to align it when installing?
