On a related note, does the belly pan behind the crossmember make much of a difference? You know, the one that covers the oil pan? I havn't had one on either of my S4's, and was wondering if I should.

(Sorry to jack the thread)

Won't an aluminum pan make for some loud/annoying noises when any debris hits it?

Maybe I completely mis-read the original post, but are you saying that your car does not have any type of underpan below the rad? All FCs came with a stock plastic underpiece that bolts from the front bumper, all the way back to the crossmember right in front of the engine. If that is missing, you just need to find one used. Most people parting out a FC will just about give them away. Also, on S4s equipped with the "aero" package, you also have an aluminum pan that bolts behind that, and covers the engine and tranny. If you are talking about something else.. then nevermind this whole post .

Doesn't on my Insight. The front underbody pan is aluminium, while the rest of the car has a plastic undertray.

Either way, I think some people are seriously overthinking this when posting. Go to the metal store, buy a random sheet of aluminium about 1-2MM thick. Make a cardboard template for fitting, then cut and bend your aluminium. Alu that thin is easy to work with. If you have issues, heat it up with a torch.

Aluminum does rust in the form of oxidization (which hey... in chemistry is rust). Next time you have an alluminum wheel at a wheel shop that has recently had the tire off, look at the internal bead, covered in aluminum oxide.

The outside of the wheel is usually sprayed with some ion coating to resist oxidizating. The ions fill the valence electrons on the outermost aluminum atoms so they resist further hydrogen reactivity. Until they get chipped that is.

On a side note aluminum oxide is whiteish grey, so its not as noticeble as iron oxide which is brownish red. Steel contains iron, hence brownish red oxide.

Peace.

i tohught the proper trem was corrision^ could be wrong though and it'd be painted, **** o dont care . . . at this rate i'll wrech it again before i need a new one < today = not a good day

Remove a hydrogen or add an oxygen (or ion of) and get oxidation (rust).
Remove an oxygen or add a hydrogen (or ion of) and get redox (reduction).

Really you can take any metal(well.. hydrogen too technicaly) and remove hydrogen or add oxygen (or ion of) and you've got oxidation or rust.

Consider H20... Water right
Remove a hydrogen. Result: OH-
Technicaly we just "rusted" water.

And I bet you were going to tell me you couldn't rust water huh?

BTW, OH- is Hydroxide...
Steel rust is called Iron Oxide
Aluminum rust is called Aluminum Oxide...

Interesting eh?

On a side not corrosion is a poor term. Something that is corrosive however usually is an oxidizing agent, in otherwords it causes rust. But... If you take Aqua Regia (High concentrate NO3/HCl- [its used for depleting gold out of ore]) and put it on your hands, you'll defiantely know about it. The Hydrogen will be pulled out of your skin and replaced with oxygen. It irritates the skin and blood will try to rush to the epidermis to try to replace the hydrogen and flush the oxygen. When blood touches oxygen it turns bright red (otherwise, CO saturated blood is blue). When the blood nears teh surface of teh skin, it appaers bright red due to instantly be saturated with oxygen.

Damn that was a mouthful.

yeah i'm heading there in the fall, i hate my dead end job and thier bullshit

WOW kenteth you just managed to make my chem intro classes usable in real life....now only if i could remember anything i learned in those classes...Looks like i won't drop out of college anymore. thanks bud.

I worked for john Q Hammons at a local hotel, doing computer network crap (reservation reconcilation and crap). I honestly though it was going somewhere. I quit and went back to school teh following semester.

I sometimes question it. I'm an Environmental Engineering. Originaly started mechanical and then changed a year later. Honestly, as much as a dislike school... After atending an engineering school for about a year, you start to look at stuff differently. You look at your car and start to see all the dynamics and what not.

But.. when some kid at McDonalds says he wasted 3 paychecks on a gun and is all proud... Ask him if he actually knows any of the dynamcis in play. After he tells you to **** off, tell him you can detemine bullet velocity, gun power efficiency, how far the bullet will go, curviture of its target implosion... well.. you owned him without needing to spend 3 paychecks on a gun to joke yourself into thinking you have a bigger ***** then other people.

Knowledge is power, its fueled me ever since I decided to return to school.

You worked for my grandpa???

Kenteth

And all you have is an FC? I'd be asking for a FD if I was you :P

Speaking of which, you should hook me up, I need a place to stay May 17th in Omaha

jhammons01

No, I am just kidding. I wish I was related. When ever I do a search on my name John Q pops up everywhere. Again, wishes was related.

Kenteth

Come to think of it, I new a girl with the same last name. Wasn't a Sarah though, know that for sure. I think it was Brittany.

EDIT:

Anyhow, back on topic, as stated the belly pan really is required. It keeps the air flowing to the radiator instead of up and under the car.... err yeah.

Anyone have picts of a homade setup?
