It's blowing black smoke and fuel smell in oil. I'm guessing rings. I was thinking about replacing with v6 if it can be done or if not can I get a step by step to rebuild the motor, please?

I would stick with the original engine, much easier than doing an upgrade. Also, the engine can be okay, you probably have a fuel injector that is stuck open. I would pull the spark plugs and see if one is flat black, this will be the cylinder that the injector should be replaced. How does it sound when cranking over? If you upload a short video of the engine cranking, I can tell if it is hurt or not. Let us know how it goes.
