Thanks for asking your question. I will try and help you out.
Can you tell me what engine you have?
Thanks for the information.
There are three things I have seen cause this.
The first is wear in the cylinders or valve guides. Even though the engine has good power. It can still have wear in the cylinders and valve guides. Most often when there is wear in the cylinders causing blowby. The engine will also have some smoke from the exhaust.
Second is a worn air compressor. Just like the engine, the compressor has a piston. When it wears, it can elevate crankcase pressure.
Lastly is a faulty turbo. They can fail and allow exhaust gas to go down the oil drain back tube and elevate crankcase pressure and cause oil to be pushed out of the engine.
Please reply back if you need more help or have more questions. I am happy to assist.
