Major oil leak! I'm about to set this thing on fire!

[Jonin]

Right gsJack, but if the rings were getting blow-by, wouldn't there be a considerable amount of smoke exiting the exhaust? And I took the cylinder cover back off and I didn't see anything that looks like a rag inside the case. Also I have another question: Does this bike have an oil wiper that is supposed to wipe excess oil coming off of the timing chain? All I see are chain guides.

[gsJack]

Any chance the top chain guide inside the valve cover is missing?  The holes for the screws that hold it go up thru to the area under the breather cover and that might put a lot of extra oil in there if they were missing.

Yes one would expect a lot more smoke from the exhaust if ring wear was bad.  It's customary to block that center slot in the head with a rag when changing shims so they aren't dropped into the sump. That's why I asked about a rag.  Don't think there is any cam chain wiper as such.  Just front, top, and tensioner rear guides.

Roger that, the top guide is there in place and I'm not getting any smoke. I can't figure this out. What else could cause the pressure to get up that high? I appreciate everyone's help by the way

.....................No leaks from anything until the revs get above 6...Then oil starts shooting out of the breather hole, like, a lot............................Also, before I gave it the revs I put my finger over the breather hole at idle and there was quite a bit of air coming out. Then when I gave it some revs the air magically changed to oil,lol

So where is the pressure coming from?  Blown head gasket, hole in a piston?    Time for the compression test I think.

Agree with getting a compression check but would be interesting to know a couple of more things about the problem.

You say it starts leaking at 6000 rpm:  Is it because of the rpm or is it possible the it starts leaking when the engine warms up to a specific temp?  I'm wondering if there might be a crack in the head that expands once it heats up or when the pressure builds up.  It would be fairly easy for the head to  crack around one of the bolt holes or at the point where a hose connects.

If for some reason the bike was overheated in it's past life that may have cracked it.  Do you remember what the oil looked like or smelled like when you first changed it?  Burned oil has a smell that you never will forget.

Good luck with the problem....and do let us know what you find.

[Jonin]

Well, if the head was cracked where a hose is connected or where it is bolted on, wouldn't it leak there instead of coming out of the breather? I just changed the oil at the scheduled time and it looked/smelled normal. As far as it leaking at higher temperatures, I don't think that's it because once I back the throttle off it stops shooting out of the breather. I will get a compression test as soon as I can take it to someone since I have no way of doing it myself and don't have much money.

ill send you a tester if you want

[Jonin]

That would be the most amazing thing ever,lol.

address?

[Jonin]

Sent ya an email with the address.

Buy a can of Brake Parts Cleaner, and douse the motor in it. It eats up oil and crap in no time. And it's very quick to evaporate. After you've got the oil off it, you should be able to trace where it's coming from better
