We steadily lowered the rpm to about 1100 rpm (Anything under 1100 and it will go straight to about 450-500rpm)
2) The car produces an exponential amount of smoke from the exhaust pipe(we were told it is because it's running EXTREMELY rich) as well as from the oil cap(when opened). We do believe that it's running very rich, but why? The smoke starts as a bit whitish, but turns bluish. As if it was burning oil. It literally pours smoke. It will drip black colored fluid out the exhaust tip, as well as shoot it a distance of roughly 3feet.( Contacted the seller about it as well, according to him it is due to the carbon build up and condensation) At one time we opened the the oil cap to take a look at what was going on while the car idled. As soon as we opened it a pressurized amount of smoke (grayish color) went shooting up into the hood. You can smell a strong scent of gas. The smoke would continue to rise out the valve cover for close two 20minutes. The car idled for only 3 to 4 minutes at max. The smoke would continue to rise out the valve cover from the oil cap opening for 20minutes.When i pulled the dipstick to check the texture of the oil. It was not slippery, more like slightly gripe.
3) Car won't go into reverse.
4) When we turned the vehicle of after approximately 30seconds a knocking noise will start. It continues in a timely manner. In a interval of about 7seconds ting......ting.......ting........ I have no idea what it could be.

1&2: To me sounds like the ECU. Open it up and take a look for a burned spot or goo (mostly near the 3 capacitors).
3: Take the end cover off the tranny, there's a good chance the issue is right there, or it can at least be diagnosed from there.
4: The sound you are describing is just the exhaust cooling off; you may also hear a drip sound which is probably the oil draining down out of the head.
It's going to be hard to properly break in a new engine with the idle/rich issue. As well as being just overall hard on the engine with the possible cylinder wash running that rich (plus contaminating the oil).
Do a compression check as well to make sure it isn't just a non-sealing head gasket, as that will make it idle bad and seem rich. Is the oil milky at all? If so, coolant is in the oil.
As soon as you get it running right, change the oil before even driving it at all.
