DIY: Dual Oil Catch Cans 370Z

Japanjay

Super interested in this since I think I am getting tons of blow by and there is a good possibility Nissan will be giving me a new short block due to severe oil consupmtion, which I think is just blow-by and will happen with the new short block. Was talking with a good friend who is into the STI scene and he was saying that they experience severe oil consumption once built with higher HP in mind. Same thing I think the motor I have is doing since it has already been replaced once, and looking like for the third time. If I am getting severe oil consumption again I am going to go this route with a dual catch can system.

1: How much volume do these hold?

2: You stated after ~900 miles you were surprised by the amount of oil caught. How much was there exactly in each one?

3: How hard are you driving this car honestly? (Comparing to my driving style so I kinda gauge an increase or decrease in total consumed volume)

4: My friend mentioned he knows of several kits that are designed to recirculate the caught oil back into oil pan so it is not wasted, most important point so as not to run low, and no need to constantly empty, another plus. Have you thought of that, and if so do you a possible way, ie: tapping a bung on the oil pan? Only reason I ask is because I was talking to another friend who is a mechanic on some trick cars and suv's and I think he going to do this for me if a: the dealership changes the short block and the consumption is not corrected or b: they figure out som skeezy way of avoiding the replacement (which I dont get the vibe they will attempt after talking with them about it)
