By not having enough oil in the car, would that create a popping sound? Have a 2001 Grand Cherokee Laredo that was working fine and the next morning it started popping. Put it had one quart in and put 2 quarts in and it still popping. Changed out the spark plugs and still popping. Hello!

If I understand your situation, you are saying the engine was run with one quart and you added 2 more quarts of oil. Now you have 3 quarts which is less than what it takes to make it full. On some engines it takes 5 quarts of oil. You will have to check the dipstick to see where you are now compared to the full mark.

If it is still less than full, it may cause some noise, but depending on how long you ran it with the oil low, how hot it got and other unknowns, you may have a serious problem. Try adding oil to the fill mark and pray that after you run it awhile the noise will go away. The noise may be the lifters trying to work with little or no pressure. It is possible that after the oil top off and a bit of driving they may pressure up and start working again.
