    There is a small little hole in the middle of the engine. After a hot ride in a trafic jam , I noticed drops of oil in my pants. After inspection I saw oil leaking from that hole in both sides of the engine, one in each cylinder. Does anyone know what are this holes for?, is it normal a small leak on it?
    Thank you.

    There are apparently allen key type grub screws that blank off the oil ways after they were originally drilled.
    Perhaps you have one that has fallen out. Check the other cylinder to see if you can spot one in a similar position.

    I have no idea of the diameter or thread pitch of the grub screws. If you can get the other one out, you should be able to match it.

    Or it might be something else of course.

    Thank you, I will compare the other side and if it didn't fall out I will unscrew it just to see the part I need. I will give you news as soon as I know something.

    I did compare to the other side and the small hole exists just the same but it is not leaking oil. I wonder if I've lost two screws or it is the way it has to look. I worry about the oil leak in the right side. Any opinion about this issue?. 20180611_010842.jpg 20180611_010758.jpg 20180611_010842.jpg 20180611_010758.jpg

    If it's an oil way blanking plug (via a grub screw) and it's leaking, I'd clean the threads out with some solvent and compressed air, unscrew it, put a little sealant on the grub screw threads, and then reinstall it. It shouldn't leak.

    I believe that is the weep hole for the spark plugs. You may want to check that the plugs are fully seated. Or, you may have a leaking valve cover seal.

    Hope this helps.

    Hi David, my 2013 California recently developed the same problem - only done 16000 kms. Have you identified and solved the problem?

    Hello Chris, yes I finally got the solution. You have to replace 4 gaskets where the spark plugs are in the head unit. Not for beginers because you have to unscrew the tower. Now it's no issue. 20190612_214021.jpg
