    BP & JB, thanks boys. I'll try that long warm up like you say first, and then see. It has leaked with the other seals on, but maybe I didn't warm it up enough before. First I will take the oil collector off and drain and clean it. I'll just run the breather hose to a pan and then start it up.

    I'll stick my finger in the oil bag. If it comes out dry, I'll top it off!

    Fire it up first...your oil bag would be low if the oil sumped and will fill up once you start it...then check the level....the only way I can think of for a pressure build up in the cases is if the crank vent was plugged or restricted...check the vent hose for any kinks or sharp bends
    And Good Morning boys:D

    If you wake up and see brown, it's not gonna be a good day,
    green side up!

    JBob, check the oil level, see if it's dropped or low.

    As BP said, check the breather tubes, make sure
    they are not restricted, could take hose off and make sure you
    can blow through it so that the hose isn't restricting.

    If you have a filter on the end of the hose, take it off
    let the hose go to a pan, when you start
    take cap off oil tank, see if oil is returning to the tank,
    if so, good, if not, you have problem.

    Either the engine is over pressuring and the seal is the
    weak leak, or the oil is not returning to the tank and/or you have
    pressure problems, or you have issues with the seal and the case
    in which case hylomar on the seal might solve the problem...

    Okay, one thing at a time. The breather is off and the breather hose was clear - started it up and it still leaked oil out of the seal area - oil also came out the breather, so I'm assumimg there is no obstruction there. I looked at the oil level in the tank before and after starting it and it seemed to be about the same. Hard to tell if oil is returning - should I see bubbles on the surface of the oil? Didn't see any. I have a brand new oil pump. I know oil is circulating through the engine because I had a leak at one of the upper pushrod covers. Once I got it on straight, the leak stopped. So oil is getting to the top of the motor. So I'm assuming it's getting everywhere else as well.

    I'm going to try and put in a new spacer as soon as I can get one. The spacer I have is a little beat up. Then a new seal - it will be the 4th try with a new seal. I can't get the old spacer off, however. Any suggestions?

    Ok couple of stupid but important question . Are we putting lube on the lip of the seal before we install them ? So as not to run the seal dry on the lip of a rotateing shaft at start up . Next around the outer portion of the seal were it goes into the case are we applying sealant there and once it is installed are we applying a small bit of sealant on the front area of the seal and wipeing it withyour finger just to seal it on the front edges of the case .? Make sure the seal is going in equal as you press it in to the case . I lke to use something blunt and made of wood like a dowel and tap very soft all the way around slow. And soft I try to get them as true as possible first buy hand.

    yes you should see oil returning to the tank

    you shouldn't see oil coming out of the breather, just oily air, I think you're
    holding pressure in the engine cases and pushing oil out every place it can go.

    Disconnect the oil return line at the tank and run a clear plastic hose out of it to a can or back into the oil tank, start and see if oil is running through the return line to the can. Dont let it run a long time but it should drain down the level in the tank and transfer it to the can the line is going to from the return line.

    how much oils coming out the head breathers, what about air amount a little oil is ok and I mean not much, should just be wet air

    something not right in the oiling system and it's forcing the oil out the seal and tube and breathers.

    What does your engine guy say about this? You should contact him
    and tell him about the problems..

    You better watch what you say - Santa might be listening!:D BTW, I let the bike run about 10 minutes.

    BP, I did everything you said except put extra Permatex on the edge of the seal after installation. I used regular motor oil to lubricate the seal before installation - also put some on the spacer as well. This time, I also inset the seal about 1/8" deeper than normal so the lips of the seal would not be contacting the same surface area as before. It is in straight and even. I did that because the spacer isn't perfect - I think it must be the original one that came with the motor.:( I think it's leaking even worse than before . . . .

    HRK, I don't have head breathers - just the crankcase breather next to the oil pump. When I ran it again yesterday, it only puked a small amount of oil out of the breather hose, and a little more oil came out from under the rotor. When I go out to start it this morning, I will run the return hose to a container and see if the oil is returning. Will post again as soon as I know.

    Mornin' boys. Sitting here sucking down coffee and a coupla aspirin to try and shake this headache.

    Anyway, enough about aches and pains. Went out to my shop yesterday and started up the beast - it's returning oil to the bag - but still puking oil out the crankcase breather and still forcing oil out of the seal area. It was 70* yesterday and I so wanted to go for a ride! But there is just too much oil coming out. Also noticed oil on top of the regulator - the oil was coming from a head bolt on the front cylinder. I'm going to check the torque on it today. The leak isn't bad, but is a new development.

    I realize that if I still had my enclosed primary, the oil leak at the seal wouldn't matter, plus the breather would be vented to the primary thus eliminating the puking problem. Oh well, I have an open primary and it is what it is. At this point, it doesn't appear that the EBOC (engine breather/oil collector) is going to work very well. It has already filled up and overflowed several times already, and I think that when it overflows it creates more back pressure on the breathing capabilities of the motor. It is supposed to mist, I know, but instead is sending more oil than air out of the vent - at least, that's the way it looks . . . .

    There are some heavy looking dark clouds out this morning, but it's 66* . . . guess it's gonna rain.

    I have some new seals and a new spacer coming. It will be well into January when they arrive and then we'll see . . . .

    Ok, now that you mention it, did you put too much oil in it considering that you don't have an enclosed primary anymore??? Too much oil???

    The engine and primary don't use the same oil. I'd check with the engine builder, maybe he made a mistake when puting it together.
