Jim,
It's the float valve(s) in the carbs. One or both is sticking open and
allowing fuel to flow up into the carb, down the intake, past the valves,
into the chambers, then down past the rings into the oil pan. You need to
pull the carbs and replace the valves. It maybe that some crud just found
its way into the valve, that the valve is shot, or that it is just not
adjusted properly.
In any case, the easiest fix is to replace the valves (either stock or
grouse jet- I've heard bad things about both, so I assume that they are
pretty much the same). As someone who tried a simple adjustment as a fix,
then had to drain and waste 5 quarts of new oil, I'd just do the value
replacement first.
It's not the fuel pump. That will always allow fuel to flow towards the
engine, even when the car is not running.
Oh yeah, don't start the car again until it's fixed. The explosion might be
fatal.
