It needs cleanup, of course, and I've got a big jug of purple power I keep around for cleaning parts. Whew, that was close! Now I think I'll blast it, wipe it with lacquer thinner and paint it silver. Uhhh...thanks? Sorry about your troubles and good luck with it!
I found out on my last project that Eagle One Mag Wheel cleaner works ABSURDLY well on cast aluminum. I bought a 4 wheeler for my gal and while rebuilding the engine I wanted to clean the cases. They were stained a dull reddish color from southern MO red clay. No purple, yellow, or green cleaner would touch the stuff. I used Eagle One Mag Wheel Cleaner and it made the aluminum look like new with very little effort! It is acidic and smells like rotten eggs while it works, but I'm telling you it cleans cast metals like crazy. You have to rinse it well and in short order so you don't damage the metal and if you use it on polished aluminum it will dull it. It will also eat paint so you have to be careful with it. Any guy that accidentally uses this stuff on polished wheels would be really pissed afterward. Anyway their general tire and wheel stuff won't do it; it has to be the Mag wheel cleaner.

evan_flatt69, this will almost without a doubt work for you but be very careful of the painted parts around it...

If I decide to try to take off the intake and try to clean it my self what kind of tools or replacement parts will I need and should I expect to run into any major bumps in the road?

Here are some pics of the damage:

I went to Lowe's and bought some degreaser called Red Max. I used it to clean my C6 trans case, it didn't stain or screw up the aluminum but it worked well.

The Purple Power I've bought in recent years wouldn't hardly TOUCH aluminum unless it was left on for several hours. This really surprises me!!

Now, the PP I bought back in the mid-to-late 80's would do a number on aluminum!!

Why is it that there's seldom time to fix it right the first time, but there's always time to fix it right the second time???

That's not an oil leak :nono: That's SWEAT from all that HORSEPOWER!! :thup:

give Alumiprep 33 from Aircraft Spruce a try. It removed the oxides (corrosion) and brightens the aluminum
heres the link: http://www.aircraftspruce.com/catalog/c ... miprep.php

its kinda high priced but well worth it.

Hopefully when we get the headers installed we'll take the whole engine out and take the carb, intake, and heads off and clean and repaint it.
