Oil leak and engine
As I was driving home the other night, I swerved into some gravel. Not thinking anything of it drove on. Stopped to fill up with petrol and noticed that a great deal of oil was leaking from the sump. Stone must of caught it. Had driven for about 15 miles. Took it to my nearest garage, another 5 miles. He has repaired the sump with chemical metal sealer, put new oil (Selenia). drove it this morning and the engine doesn't sound right? Drove fine for 3 miles home. Any ideas what couold be and how to fix it?
