As some of you may know, I was in the process of putting together an offy 3x1 setup on my 72' Nova 250. I had everything done, new radiator, water pump, hoses, belts, fuel pump, custom bent hard-fuel line, carbs, intake, Langdon's headers, custom fabbed linkage system... ect.
We were putting coolant in, and high-fivin "yes! its finally assembled!" And in the process, coolant filled up the water jackets of the water-heated offy intake. And then we noticed a sizable leak and were like, "oh great". so we wiped up the excess coolant to locate the leak. And to my dismay it was coming from the little "smooth" plugs, which I think are offy cast expansion plugs. I couldnt believe it. I then, despite the steam shooting from my ears, disassembled EVERYTHING, and found, yes, that IS where the leak was.
Now, my instructor and I were thinking about drilling a hole in each plug, and pulling those out, to put in real brass freeze plugs meant for heads/blocks. But I dont know how well that would syn with an aluminum intake.
Help! I need a little guidance! ASHFDkjasldf!!$%@#$
