I decided to fit breather kits for my both engines (2wd and 4x4) and leave kidney boxes.
I have two more questions.

1.I want engines to breath also from the exhaust side.
Is this the right plug I should remove and fit a hose nippel?


2. Connecting oil drain hose from oil separator.
Could I use turbo oil return pipe? Would it be under the oil level or is it a bad idea, because it's above the oil level?
The 4x4 kidney box has some oil drain hose, but there is no such in 2wd.
What would be the best way to fit oil drain for 2wd and 4x4? Should I drill the sump?




I will be very grateful for answers
