    Compression yes, leakdown maybe

    See WC Engineering : Compression and Leak Down Testing

    You want to first establish that you have a healthy engine there before tossing parts at it.

    Keep in mind you three things for the engine to work too..

    Air - Plenty of that around

    Spark - You can move plugs and coils pack around to validate there is spark

    Fuel - Check the rail to make sure there is pressure. If so, then move around injectors to make sure they all work.

    Welcome!
    Sounds like it has some issues...
    +1 for making sure the engine is healthy internally before throwing parts at it...
    My guess is if the car was sold at auction, and will nor drive, it was more of issue than a small dealer with a part-time mechanic wanted to dealwith.

    Welcome to Motoring Alliance. Thanks for joining.

    The first thing I would do is a compression and leakdown test on each cylinder.

    But I can't move the car. Won't drive. Is that something I can do at my house?

    Misfire usually means a mechanical fix is needed...sometimes it is a plug, wire or coil issue, but often it is a valve or piston issue...
    You can move plugs or replace...the coils can be moved to see if the issue follows the same coil....can be done...
    A compression test will tell you if the cylindar with the misfire is mechanicaly sound, and with a bit of skill and a bit of extra info if the valves, headgasket is ok or blown.
    Good luck, interesting project car....i hope that was what you wanted!

    Sounds like a valve cover gasket failed. Those spark plug tubes go down though and that is where oil would come in at...

    Or, even worse ring failure... thats a rebuild!... would also make sense why you got a $6K 08

    Best of luck to you!

    If you're good with cars, I'm sure the car ended up in great hands. Great project by the way.

    I can't remove the plugs. I tried all my tools on it and can't find the size. I tried 14, 1/2 and others. Is there like a special size for these plugs? On my 300C I used 5/8 to remove the plugs. Do u know the size for mini?

    I believe it is a 14mm 12pt very very thin wall socket. I don't think you will find it at the parts houses. You might have to chase down a Snap-on or Cornwell truck.
    I am sure others will be able to give you some more solutions.

    You can obviously sop it up with some shop towels or something... Maybe some electrical friendly cleaner like MAF cleaner? WITH THE PLUG STILL IN. I wouldnt chance getting anything into the engine.

    It's just going to fill up again if the valve cover gasket is shot.... Maybe check that the valve cover is tightened down enough...

    Hey! Had the same issue with my 2004 Cooper S. Compression test showed nil compression in Cylinder #2. Leak-down test was super bad. $2200 for a valve job or $5500 if it's more serious than that. Right now, I am weighing my options for a salvage motor for $2500. Sorry to hear it. Sick Minis are sad...
