Good luck in resolving the issues. Purple smoke is more than likely oil though so don't expect that to clear up. IMO the OP at least owes some answers to Alpha D regarding who rebuilt the engine, etc.

When selling a used car please be as up-front and honest as possible. When buying a used car, especially a modded one, be sure you know exactly what you're looking at and ask the questions that require detailed answers. If either party is getting a bad vibe then just walk away.
