NEED TO CLEAN MY ALUMINIUM INTAKE

[WILMASBOYL78]

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.
