#278069 White smoke out of exhaust is burning coolant which means blown head gasket or cracked block (less likely). If the smoke has a blu-ish tint, it was burning oil which could mean rings or valve seals.
If oil was squirting out of the dipstick hole, you've got a lot of pressure escaping your combustion chamber, making its way to the bottom end of your engine - usually a sign of shot rings. Either way you might as well start by pulling the head off to see the damage.
Did you check the oil and coolant to see what it looks like?
