my upper intake is off my car and while its off, i opened the inlet hole to 75mm instead of 72 or whatever it was before... now i know there are some medal shavings down inside the intake....

anyone know of a good way to get all that out of there?

my thoughts were dumping some gasoline down in and shaking it around and dumping it out. doing that a couple times until i know all of the shavings are out....

any other ideas?
 
fill it full of brake clean and throw a match in it!!!!

let us know what happens and take lots of pics.

seriously, +1 on the garden hose. or fill it full of chemdip and let it sit a day. that will remove all the carbon in there as well.

water wont hurt it?

Water is in the air you breathe, and so does the engine. As long as it doesn't get water poured into throttle body, it will be fine. I would recommend soap and water, with a really long bottle brust, then rinse it with fresh water, then take compressed air and spray it out to get the majority of it out.

got access to a hydraulic press and a bead/sand blaster? Press the freeze plugs out of the ends of the upper plenum and blast all that stuff out of there after solvent cleaning it. When your done, press new freeze plugs back in.
 
I use Gunk foam engine-brite myself....just douche it down with that and let it set a few.....shake it around some, then hose it out....It will remove 95% of the Black crud....blow it down with compressed air...
If you been porting and have it full of slivers and filings then soap isn't gonna cut it to me...I want something thats gonna cut thru the crud and get the filings stuck in that crud...
