if it sounds like a loud lawnmower, or helicopter then its the bottom end bearings.

Had that sound on my old engine, tore it apart before putting in my new engine, all the crank bearings were scored.

Every engine gets some white smoke, and water for the first 5 to 10 mins. beyond that, does your coolant level get low? could be leaking coolant internally.

Later man.
