about two days ago i was visiting family in another state, i left later in the night and about 4-5 miles in to my trip i noticed power seemed down(car was not hitting sixty like it normally did), shortly after getting on to the highway with a speedlimit of 65 mph my low oil pressure light came on, i started to pull over immediately and then the engine started making a very loud noise and the check engine light came on(this all occurred in a matter or 10-15 seconds). i shut the car off and call roadside assistance. i checked the oil and saw no metal and the oil level was still near full. the flatbed comes and despite me telling the fellow not to start the car, he starts it, throws it in to drive and stomps on the gas to get it on to the tilted back flatbed. fast forward to today i had to call the dealership(they didnt bother calling me for some reason), and was informed there was metal all over inside the engine, i was not informed what caused this but that they needed my oil change records. the first oil change was around 7200 miles, and the second was around 14500 miles, both at the chevy dealer. the next two were done by me, at 21,000 miles and 29,000 miles using quaker state full synthetic oil. i have receipts for when the oil was purchased and work tickets from the dealership for warranty work done(the car has been a nightmare since ive bought it). the oil is dexos approved and the filters were not cheap. at this point the car has around 34,500 miles, i should be finding out tomorrow whether the car is covered under the power train warranty, which is 5 years/100,000 miles. so im looking for insight on what might have caused this problem and what to do if chevy wont honor their warranty, as i cant really afford to replace the engine. my thoughts on the cause would be the oil pump failing, i figured since the car was already making horrid noises before the tow truck driver abused it, the engine was already damaged. i would appreciate any feedback, thanks.
