So I was out yesterday almost home an the stop light came on with oil light, so got back carefully checked oil it was low so put a litre in that I had, let it settle for half hour then when of out via the garage a mile up the road got another 2 litres put it in, fort nothing about letting it settle jumped in an away I went fort about a mile down the road I should have let it settle .
So couple miles later with stop light on it got rough an wanted to die so stopped an left it till today then started in wouldn't idle went again with slight rev an was fine but fair it of smoke from exhaust and tapping a lot
What's likely to be the damage
