4 into 1 without tuners

from what i understand of what the fella telling me was saying was that if it is way rich the excess fuel will wash the oil off the cylinder bored then as you say run out the exhaust. he was talking super rich tho so i doubt this would ever apply to a factory setup with a pipe. i guess by washing off he meant partially disolving the oil with the fuel but who knows. he may have jsut been pulling my leg. sounded serious tho and i can see it might happen
