Drained Oil pan, Gasoline in OIL!!!!!
1993 RX7 13B with about 40k miles on rebuilt motor.
Has been blowing white smoke and barely stays running at idle. Won't run when shifted into any gear.
Went to drain the oil and found it to be very thin in consistency and strong smell of gasoline in the oil itself, which explains the thin like consistency but how could that much gasoline end up in the oil???
Any thoughts???

What mods do you have done to your car?
Seems pretty normal for FD's to have thin oil and a strong gas smell if it's running rich or is modified heavily. It also depends on the motors build tolerances. I recommend changing your oil more often in this case. How many miles did you put on this oil change? It sounds like this is a new occurrence though so this may be indicative of something else. Did you modify the car any during the last oil change period?
White smoke is normal at first startup - it's condensation in the exhaust. If it's a lot of smoke and it still continues after warming the engine up, it could be coolant. You may want to pressure check your coolant system for leaks. You could also try running the engine with no radiator cap to check for bubbles and to see if it runs any better.
If it's a a greyish white smoke, you may have bad oil control rings. This would explain thin oil with a strong gas smell because any gas in the combustion chamber could then get into the oiling system. Check for oil on your spark plugs.
It could also be a stuck injector like lduley said.
If it's possible, a video may be better for troubleshooting this issue. Try to get the engine idling, the exhaust smoke color, the coolant radiator cap off and the engine warmed up in the video.

Black smoke = too much fuel, with fuel odor
Blue smoke = burning oil, with burnt oil odor
White smoke = steam, coolant, vaguely sweet smell
Some fuel dilution over time is normal, especially in cool temps. But from what you're describing I'd suspect too much fuel...a stuck injector, or possibly really bad side seals. Pull the plugs and see what they look like. If one or more are damp with fuel, that might confirm. Otherwise I'd probably do a compression check.
