I have a 2009 Chevrolet Colbolt SS Turbo with no obd codes. I was blowing blue smoke from the exhaust, which smelles like oil. When I first start on the turbo, it emits a siren sound that sounds like it’s going up and down. Won’t exceed 5 psi. I recently had a rear-end crash. Is my turbo fucked?

Yes blue smoke usually means turbo is bad. Is there play in the intake shaft? How many miles on the turbo?

120k miles. 2 bar sensors, zzp down pipe and zzp tune. I’ll check that, I haven’t had time to inspect the turbo yet just getting some knowledge about what I’m about to tackle lol

As a former owner of an SS/TC, simply flee it now. Go as fast as you can.
