2005 Subaru Legacy engine problems

Dt*: the contact stated while driving the vehicle was hit on the front passenger side, near the bumper and wheel. The other vehicle impacted the vehicle at 40 MPH. The airbags did not deploy and the engine did not shut off. The manufacturer determined due to the angle of impact the airbags should not deploy. The contact was wearing a seatbelt, but sustained whiplash. There was a police report taken at the scene. The vehicle was towed to the dealership.

Check engine light came on, pulled over immediately and checked oil on the side of the road also looked through owners manual. The oil was a quart low, turbo making suction noises, pick up from a stop or quick throttle to pass on high way was gone. Added a quart of oil and had an oil change & check engine light diag done the next day ( drove maybe 60 mile with light on). After the oil change metallic noise from passenger side of engine could be heard and exhaust was pouring out thick smoke.
