Stock port with a holley 4 barrel and racing beat intake and exhaust. When it sits it smokes a lot when started and is a white color but kicks out this gray oily liquid out the muffler. . What's Wrong?

It's either bad oil control rings in one or both rotors OR water mixed with oil. Sure looks like oily water to me. Does it smell sweet?

 

Thats not gray, that rust and its from water condensing in the exhaust system and getting spewed out after the first startup from sitting for a period. I wouldn't sweat it too much.

Watch your coolant overflow if you think its using coolant, its always a good indicator. If t he exhaust smells sweet it could be coolant but I doubt it.

 

I don't smell any sweetness over the strong gas/oil smell. Like a 2 stroke concentrated. But these always have that strong snowmobile smell lol I don't drive it often but it had been doing it fora while now.and the oil looks clean but of course had the gas aroma to it but that is to be expected. I had a 21lb rad Cap on it by accident up until about 2 start ups ago and gotta 13lb since then. I premix so maybe it's oil that settled in the tank over long sits? The plugs were darker Brown but not abnormal for these. And it runs what seems to me like normal.

 

Stop obsessing and drive it until it breaks. LOL.

 

Haha! That's what I'll end up doing. I'm not wanting to swap it right away especially since I just got done painting it. It's a quick way to ding it up. Lol

 

This is what I'm thinking as well. Condensation will definitely build up if the car has been sitting outside.
