I was hoping I could get some opinions on an issue I have.
After breaking in and running a rebuilt Pontiac 400, I noticed that there was a little bit of water dripping out of the exhaust. I concluded it was condensation, although I was a little puzzled why there would be condensation from running an engine in a heated shop. I remember before I tore down the engine, it used to drip black sooty water.
To trace down a few other leaks at heater hoses, freeze plugs, etc, I pressurized the system to about 16 PSI. There were no external leaks, but the next day the pressure was completely done to zero. I am scared to death that there might be an internal leak like a head gasket, cracked block, etc. I have a few ideas to check for water leaks but haven't been able to try them yet.
The machine shop bored the cylinders and rebuilt the heads, (they pressure checked them, I'm not sure of the block.) They said the block didn't need decking.
My question is should the pressure remain in the system indefinitely?
