Major oil leak, help!

So I'm not exactly sure why but the case is pushing a lot of oil into the air box and then it dumps out of the air filter. In 20 miles it dumps an entire quart. I have no clue why. Thanks in advance.

 

Stop riding it.
The simgle most likely cause is that it is not just dumping oil. It's dumping a mix of oil and gasoline. Give it a sniff.
If the oil does not smell of gas then the crankcase was overfilled with oil, and what is coming out is the excess.

If the oil smells of gas then you will need to service the carburetors, and test the petcock for leaks (may as well just rebild it though).

 

Have you done any work in the engine recently?

I worked at a Triumph dealership some years ago. Repairing a bike after a crash, the left side cover (over the stator on this particular machine) was ordered and replaced. The service manager who ordered the parts did not notice a seal located in this cover, nor did I as I swapped it on. The end of the crank ran into this cover, and there was a breather going to the airbox. Long story short, after the work was done I had the bike running on its kickstand while I put my helmet and gloves on to go for a test ride. It started to stumble and sputter, so I whacked the throttle to clean it out- BANG rod through the block and oil on the ground. WTF? Apparently, that missing seal allowed the motor to pump oil right into the airbox, and when I opened the throttle it sucked about a quart of oil in and hydro-locked it.

If @k-moe is correct, you just have a small amount of oil and a large amount of fuel from a leaking float valve and/or petcock (or severely overfilled crankcase). OR you could have a crankcase that is getting pressurized somehow (ring blow-by, for example).

 

There has not been any work done on it. Its not gas either, it's also not overfull. As soon as I put the oil in it spits it all out. It seems to be a ton of blowby in the case for some reason. I'm not very engine smart so I don't understand why.

 

Make a compression test, that will reveal if you have bad rings.

 

I had no problems with mine then I blew the head gasket and I got oil in the air box constantly. so like Big swede said check your compression, you may have a leak, rings or gaskets...

 

Thanks guys, I will do the test and report back

 

How much oil did you put in? Full drain and filter, or just fill and drain? Oil cooler or no?
