Vauxhall Corsa Oil Problems

[adtyke]

Got a 51 plate Corsa,having to put approx 1pint of oil in per week to keep topped up.There s no oil on the ground so unsure whats happening.Had a new oil sensor fitted a couple of months back also had oil change done at same time.Any ideas out there?

If its not leaking its being burnt. you dont say what mileage you're covering but to use a pint a week I would expect you to be doing at least 1000 mls. a week. Several things could be causing it including worn valve guides and seals, piston, rings or worn bores. Was the HC reading high at its last MOT
