Thick milky white smoke with a sweet smell usually means coolant is leaking into the combustion chamber from a bad head gasket.

Do a compression test for the smoke. Where is this scraping noise coming from?

In that case, I'd do a compression test first, to see if it is the head gasket that is bad.

As far as the scraping noise, I don't know. It would be best to pinpoint exactly where in the motor this noise is coming from.
