Default Re: Cleaning an early aluminum intake

I expect this has long been outlawed by the EPA, but in the late 80's this Ks boy found himself working and living in the SoCal high desert. Purchased an off topic 67 Merc ex sheriff's car with a factory Hipo FE and rare aluminum intake. Car had over 200K miles. Disassembled the engine and the intake was so bad the heat riser crossovers were caked solid with carbon. Took the intake into R&E racing. They did what they termed a "cold tanking" of the intake. It cleaned out all the carbon and the intake came out perfectly like new!! To this day I have no idea what they used, but sure wish I had been wise enough to ask at the time.
