What is causing oil to show up in the air cleaner assembly.

It's like blowing right at the air cleaner from that air breather hose, coming from cylinder head cover.

Take a look at the top on the rocker cover where the Camshaft position wires come out, the oil can run down the wires into the ECU and MAF, many threads on this problem

I'm 100% sure that oil comes from this hose pipe. This pipe is connecting cylinder head cover and part of air intake (between MAF sensor and air cleaner unit itself).

Thanks
