    Hi All

    I have a mini one 08 in Thunder Blue with silver stripes. She’s beautiful but has some issues!

    It has started jumping in low rev bands and is now more frequent and happening at higher revs as well. I bought it 9 months ago and had O2 sensors replaced then with similar issue. I wondered if anyone knows it’s that or something else. It has an oil sweat the garage recommends re-sealing sump.

    Hope someone can help.

    Thanks
    Steven

    Welcome to M/A Steven. A little more information would be helpful. Mileage for one. Do you have any previous service records? The more you tell us, the better we can help you. And, pic's are always appreciated. :)

    Thanks for replying.

    It’s done 85k and only a couple of stamps in the book from a few years ago.

    It runs well but needs oil more frequently.

    No visible signs of oil, would I have to get underneath it to take useful photos?

    Cheers
    S

    Welcome to M/A, Stephen! My MINIs are all Gen 1s so I cannot be of help here. Even so, there are a lot of guys here who have the experience with Gen 2s and hopefully can be far more helpful than I.

    Good Luck and welcome again!

    Is it a Cooper S?
    If so these are signs of posable carbon build up on the intake valves. The S has an N14 engine that is direct injection. Because the gas is injected directly into the cylinder It does not keep then intake valves clean from the oil vapor from the PVC system. Once it starts to build up in the valves the engine starts to run rich due to decreased air flow causing ruff idling/running and oil consumption goes up. This is fixed by having the intake Walnut blasted around 50,000 miles. This can cost anywhere from $300-$800. If the car does have carbon build up in the intake and you don't address it you will destroy the motor.

    If the car is a non S just a Cooper none of that applies. If you don't do your own work and need to find a shop close to you that knows how to work on MINIs someone here may be able to help.

    Welcome to MA.

    Post pictures of your whole car so we know what we are dealing with. We don’t really need shots of the underside, just pictures from the top of the motor and car.

    Where are you located? USA ?
