i have had this happen to me before i 2 different cars,
1st the oil light comes on,
u check ur oil but its ok,
drive down the road and it goes bang!!!
i would be worried if i was u and i wouldnt drive the car because if u get it fixed before it goes bang then it will cost u less ,
everytime a car has blown up on me i have had theese exact symptoms,
usualuuy its because the oil is actually low, but it reads ok on ur dipstick because the oil isnt actually circulating to the bottom half of the engine only the top,
get it to a mechanic quik m8, could be headgasket or bottom end related but in my experience oil problems lead to bad things
