Hi I had repeted oil pan craking and leaking, last week I had to change the power steering pump and now it's keep leaking from the oil power steering reservor and oil pan, the oil in the power steering is black so it's telling me engine oil pressure to high in the pan and it's goes true the power steering reservor due to hight pressure.

I'm wandering if there is and check valve or blow-by oil filter that may keep oil pressure inside the oil pan.

any help would be appreciated.

Is it possible that the turbo leaking air pressure in the engine oil?
I just had my turbo rebuilt because the seal was seated wrong and was boosting into my crankcase. I had tonnes of blowby and now I don't.


Check your blowby and check your crankcase filter if you have one and make sure your blowby tube isnt plugged because if it's plugged and your boosting into your engine, you'll have seals blowing out
If you are getting black oil in your power steering then you may have a bad power steering pump. You also need to check the blowby pipe coming from the front of engine to make sure it is not stopped up. It can cause pressure to build up and force oil back into the front of the power steering pump
The power steering pump was bad thanks
