    Crankcase preasure and oil leaks.

    I'm leaking oil and it seams to be getting worse. I know stuff wears out and gaskets fail but I'm wondering if there's to much pressure building in the crankcase. When I first bought this I checked the drains. One plug was missing (stuffed a stick in is what was gong to be a temporary fix), the other was there and had some sludge. I checked them today (almost a year later and lots of cold and hot weather riding) and nothing.
    If this could be part of the problem, how much will I have to take apart to clear the lines? A 1-5 difficulty would work for me. If it's removr the tank, carbs, cylinder heads or the whole engine, forget it.
    Thanks, Eric

    is your main breather hose from the back of the motor still hooked to the breather box?

    if it is you should be ok

    Thanks for the reply murrayf.
    No, not a lot of highway, maybe 2 hours in a year. I like the back roads better.
    I'll check the tube. Do you know if the engine side has a screen? I had an 87 Volvo that started leaking real bad in several places (blew the valve cover gasket too) . It had one and it caked closed. That was an easy fix.
    I can't see the PDF version of the FSM well. One picture looks like it connects somewhere behind the timing hole. I try later to take it off and see if it's blocked and trace it around. I also thought maybe just the O ring on that inspection plug, that should be doable with everything else in place. Hoping it's not the front cover gasket, OP switch, fan seal or anything that's a pain in the....
    Wouldn't NOT having to take half the bike apart be GREAT!!!!!
    again.

    If YOU are leaking OIL I would say it's time to go to the doctor



    From the description, I can not imagine where it's leaking.
    Out of a rubber line/tube under the air box ?

    Front cam seal will get right to the underside at the back too if bad enough.

    The fairing and radiator are in the way but somewhere on the front and it seams mostly on the right side. Gravity, wind and the front shape may just move it to that side.

    Remove fairing and radiator and fan to come to the leaking oil seal.

    You have to buy: Two oil seals (cam and tach drive), one gasket.
    The part numbers You can see here.
