I was once told to try a small detail stainless steel wire brush. Don't know if it works or not.

Eagle 1 makes a real potent aluminum etching cleaner. You spary it on and let it sit for a while then hose it off. Should clean the intake up.. Not something you want to use on your vehicle's aluminum wheels however. The stuff is very strong...

If this does not work you may want to consider painting the intake. Alumiblast paint works excellent on the intakes and holds up very well after time...

We have a reskinning-tumbling process. Have done thousands of intakes, valve covers, trans parts, blocks, heads, etc. A wopping $120 plus shipping. Meets NCRS standards too.

Bill, is that yellow "tinge" from leaking fuel..??? I have seen lots of aluminum intakes with fuel stains, but that looks like the whole manifold is tinted. For spot cleaning, I use a little spray carb cleaner or brakeleen...spray it on rag and try wiping a small area and see how it looks. Don't spray all over the engine as these things may take paint off...I have also used a small brass brush with something milder like wax & grease remover, WD-40 or Simple Green...the brass brush won't hurt the finish...go slowly and see how it works. You may want to remove the carb, plumbimg, etc....tape off the valve covers, painted areas of the engine and kind of secton off the intake while you are cleaning...don't forget to put some tape over the carb area on the intake. Good luck...

PS....one other thing...check the bottom of the accelerator pumps and other common leak areas on the Holley...I know from experience they can leak and cause this kind of problem...if in doubt, call Eric Jackson and have him go thru it while you have it off the car...he does GREAT work.

Manifold looks like it has been cleared

They often turn yellow like that.

Looks like a cleared intake. I see alot of street rods and street machines that people do that to. The enamel from the the clear gets hot and turns color. I am also not crazy about a bead blasted only intake. That is not the right look to me. Brass brushes are less abrasive. JMO
