It started doing this after i drained the coolent from the main drain plug on the motor....
Water seal????

 

I don't see how draining the coolant would cause this to happen. Is it coming out of the muffler or just the engine area? If it's in the engine area it could just be residue evaporating. Check coolant seal by opening rad cap. Rev engine to 3-4k. Look for lots of tiny bubbles. A giant burp is fine.

 

the white smoke comes out of the muffler...
i took off the cap and no overflow it will only smoke when
its cold for about 15 20 mins then it wont smoke anymore at all...
and my car doesnt over heat...
but the sweet smell is still their

 

you sure its not burning oil or you have leaking fuel injectors?

 

no its not oil cuz it smells like coolent....
oh forgot to mention the car dose start off running off one rotor
then its like the second injector kicks on....
but it never smoked before just yesterday out of no were
i drove it fine then came out 20 mins later turned it on and
their it was a bigg *** cloud of smoke

 

Pressure test your cooling system. But my guess would be on leaking/dirty fuel injectors possibly overheating your cat (i'm guessing you have a cat since your in CA) then making it smell like overworking cat sulfur-ish smell.

Don't forget to also do a compression test on the engine.

 

How would i pressure test it????
Nope im straight pipe

 

Go to autozone or advance. Ask for a coolant system pressure tester (rental tool). Follow instructions on tool.

Compression test using compression tester attached to spark plug hole.

Now it's starting to sound like you would have a coolant issue....

 

thats wut im trying to figure out cuz im stumped
