Motometer and loose fit/leaking water.

Ah, more of the simple questions.

I have a motometer on my '30 Sport Coupe. When it gets warm, and the engine gets into high rpms, I get green foam coming out of the neck of the radiator. I really thought there was something wrong. Sprayed the radiator shell, windshield, everything. I have water/anti-freeze inside, so I guess that's where the color comes from.

I installed a new gasket between the cap and radiator neck, and a new one between the cap and the motometer. There seemsed to be a cork gasket up under the motometer upper part but I couldn't find a replacement for that, just the neoprene red on the goes on top of the lower half (above the hex screws). The problem is, the meter seem loose when I close it on the cap, like the red gasket isn't sealing. My father-in-law says it's the clips on the meter. "All you have to do is bend them down gently with a hammer so it pulls the cap down farther." AHHHH!


I have two questions:

1. Is this green foam normal, but just usually inside the radiator, Or do I have oil (from the engine) or grease (from the water pump) getting into the water?

2. Do I need to replace that cork sealer, not just the red ring, or should I do like he said (horrors) and bend the clips down to make it fit tighter? I really have reservations about doing that. I hear these are expensive, and hard to find accessories.

Thanks in advnace for the help and patience.
J.R.
