    You can get a partially blocked cyclone which is the breather on the drivers side, the blow-by will then assist oil leaks. A seal is likely, but try and replace the cyclone block breather, the replacement looks something like this

    Depends where the leak is originating, the breather is sealed with o rings and easy to replace.
    If you have oil running down the block and dripping, it is more likely to be valve cover or vacuum pump
    Clean and degrease, then check where leak is coming from

    I had oil showing up in the air filter which was a worry. Replacing the cyclone fixed it. I had previously done the suction test to make sure the diaphragm in the cyclone was sealing ok, which it was.
