Does anyone know where I can find a crankcase breathing diagram for this little engine? I am finding oil in my intake and I am afraid that there is something wrong with the system. I see oil coming out where air should be going in. Engine doesn't smoke and has plenty of power. Compression good. Any help would be appreciated, also if anyone know where the vacuum comes out I could check that. Thanks!

I looked on some other posts and found the vacuum from the crankcase, this is where the oil is entering my intake. When I removed the breather tube and open the butterfly all the way and look down the throught I see oil, some is puddled on each side of the split. There was also oil clear up the other side of the manifold at the second butterly used to split the 123 and the 456 ports. This is too much oil. Any ideas? What is inside that assembly that attaches to the block and the breather tube comes out of? This is a frustrating mess. I have had 4 external oil leaks, now this! Please help.
