Engine Coolant Pressure Test Procedure

I have reason to suspect one of my cars is leaking coolant from the intake gasket, just like the horror pictures on here where you can not see it until you pull the manifold. I bought the coolant pressure testing kit - with the adaptors that go between the radiator and cap, and a pressure pump and gauge. But there are no instructions! Rather than make it up, what are the right steps to use my new toy, I mean tool set?

Thanks! I will get pics after I get some paperwork caught up. I bought a kit off of Amazon, but the big red case does look familiar. It is a Forgemech 21 piece radiator pressure test kit. Cheap, but the pump and gauge seem better than the Stant brand.

The oil looks great. I still need to inspect the plugs. If it is parked for a few days or more, I get white smoke for a bit and it runs rough at startup while smoking. The longer it is parked, the longer the smoke and rough running. After it is warmed up, it runs great. When run every day, it does not smoke etc.

I also have a mystery fluid that builds up in a dip on the manifold that is right below a bolt that is supposed to be blind and dry. (Was that run on or specific?)

Just in case I can not tell white smoke from black smoke, I backed the electric choke way off and have checked the float levels while parked (via sight plugs in a Holley). It does not seem to be fuel related.

I will post again with results, hopefully before it snows.
