Hi there,
I think that you need to take a step back and evaluate what you have done to date, firstly as saturntech has stated, there must be a build up of crank case pressure to cause this problem, this cam happen with a blocked PCV, excessive oil in the sump and often engine blow by, this is when engine compression leaks past the piston rings and starts to over pressurize the sump, causing oil saturated air to be forced out the engine seals, and breathers, often you will find that the air filter is covered in oil to some degree, what you first need to do is check the PCV and have a leak down test done as this will be a good indication as to the condition of the lower end,
you can archive the same test results with a wet & dry comp test, this will show any extreme variance in piston ring sealing capability.
