had this thing basically rebuilt (new pushrods, machined crank, new valves, blah blah blah) and after sitting for two weeks it puts out puffs of white smoke when i give it gas in neutral. it was having some problems staying at idle a couple weeks ago so i put in a new carb, but i don't think this is part of the problem. what's going on? oh, and i noticed an oil leak in the passenger side heater box (under the car where the two parts of the box come together at a seam). could this be related? anything to worry about? it seems like there's always something with this car...
