Car accident, car flipped upside and remained in that position for over 30 mins-will my engine need replaced?

"Year?" With the Newer Cars/Engines the ECM will Shut it Down when it Detects a Problem. Yeah Engine may be fine; need to Drop the Oil Pan, Pull the Head(S), Flush the engine, Replace Plugs & Wires, Check for Distributor Block Damage and then see how it runs. "Good Luck!"
