Your oil level can become overfull in 3 different ways.
1) Coolant – intake gaskets, cracked cylinder walls, busted radiator if equipped with an internal oil cooler
2) Transmission Fluid – busted radiator if equipped with an internal oil cooler
3) Fuel – Fuel Injector Sticking or Stuck Open. Leaking fuel into cylinder can wash out rings and fill oil pan and contaminate oil. Usually will cause blue smoke as well. (Most Common)
