Hello, I have a 91 Camaro with a 350 carbureted engine. I recently have incurred white smoke at start ups and then it would go away. Now it white smokes all the time. The smoke smells like gas and oil burning. My exhaust tips have turned a dirty brown/black also. When I turn the car off it smells like gas for quite a while too. If anyone can assist me with what might be the problem I would greatly appreciate it. My guess is valve stem seals, but not sure why the gas smell?

Thanks,
Dan

 

pretty sure that means you are running crazy rich

 

my car smokes bad like that too! white/greyish smoke from tailpipes and stinks like hell! if I stand near it for too long, about 5 seconds, it feels like I may carbonmonixde poisoning.... real strong odor like when u pull a car in a garage then shut it off and u get that lingering exhaust fume smell... ;-)
my car is an 85' with only 86,000 miles .. could it still be valves like mentioned above??
