If there's no oil on the dipstip. I'd be concerned.
Don't run it till you confirm you have oil.
If a head gasket goes you can tell by pulling plugs and inspecting them.(One very clean one compared to the others)
It may also be noticed, if you have a lot of pressure in your cooling system (bubbles in the rad when running),
I'd do a compression check too.
Condensation is normal in this type of weather.

Car has been sitting for approx: 3 weeks, without any engine starts. "Right away, I figured Blown Head Gasket?? BUT, Dipstick shows no evidence of oil in the system. Engine was professionally built and Dyno'd. All that has been done is changed Tunnel Ram Intake for Edelbrock. Any suggestions would be appreciated.
