wrecked my four wheeler down a hill it fliped multiple times and bent the rear axle so I replaced the axle right off the bat looking closer i bent the frame bars and broke the black ring around the tank. ok I can live with that. but hears my "big" problem. i changed the oil and straned it through a paint filter I got a large piece about a cm long of steel along with a bunch of smaller pieces that were hard to see. it was ran for about 10 min after the wreck before I changed the oil the first time. after I put the new oil in it I ran it lightly for 5 min and checked my dipstick and my oil is black already. I think I have a bad crank and piston rings. And I know its not runing right. will this become a money pit like I think it will be? What shouild i do?
