Car runs great but blows soot when you give it gas and is getting fuel in the oil

This can be a leaking fuel injector, check to see which spark plug is fouling up with fuel, that will be the cyl with the suspect injector.

Fuel pressure reg may be faulty, excessive fuel pressure can also cauls your problem, get the rail pressure tested next.
