DIY: Dual Oil Catch Cans 370Z

37Z · 07-02-2012, 08:29 PM

[QUOTE=sixpax;1787627]... back in March at roughly 7,035 miles I had installed this dual oil can catch set up ... today at 7,915 miles I decided to empty both of the cans just to see how much was in there. Was more than I expected, but more unexpected was the fact that the driver side can probably accounted for about 70% of what is in the bag ... 30% from the passenger side can. Weird, I would have thought they would be somewhat even.

Any update on the amount of oil from each of the oil catch cans is appreciated. Is the passenger side oil catch can routing a cause for this oil catch can to trap less oil compared with the driver side one?

Tip: Add a hose from each of the oil catch can drain valves to the bottom of the engine. When you change your engine oil, drain the oil from the oil catch cans.. no need to remove the oil catch cans!

PS: Another oil catch can setup is Speed Force Racing - Your forced induction specialists that was designed for a twin turbo 350Z setup with custom dual intake plenum with dual throttle bodies. I am not sure they are still in business though.

I am not sure why the volume captured on each side is different. Great tip, but I assume you would have to drill some holes in the motor to attach the lines ? Not really hard to drain them the way it is now. Nice set up on that 350Z !

No need to drill holes in the motor! Add a hose of sufficient length the the bottom of the plastic engine belly pan cover. Route the oil catch can drain hose to an opening through the engine belly pan cover.

Very nice write up!

Those are excellent OCC's -- I had one for my old SC'd Celica, and it worked beautifully.

I like them ... I think his design is great. Way better than just an empty can.

that is an awesome idea man!!!! ^^^^

That's not what the original set up called for?

Nope ... the original post, pictures and installation are only trapping the blow by, not feeding it anywhere. It's a great idea, and seems like a few different ways you can do it. I have not done it, and am content at the moment with just emptying mine every 1,000 miles or so.

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)

1. Not sure. I have the Micro Style which is a cylinder 2 inches in diameter and 4.5 inches tall. Not all of that area is available for "storage".

2. Didn't measure it, but I would guess around 3/4 of an inch at the bottom of one and about 1/2 inch at the bottom of the other.

3. Like a baby on the street, like an old fat guy on the track (only twice) ... car is not a DD so does not get driven every day.

4. Great idea to recirculate, I think. In looking at the stuff collected in my cans I don't think I am very interested in shooting it back into the block. Condensation makes it a little "watery" in texture and appearance. I'll just dump it out and be thankful I am keeping that out of my engine.

Ok. so this is were I get confused. My 2012 is a daily driver (120 miles a day). I drive in all kinds of conditions; sit/go traffic, fast highway speeds, and back and forth between the two daily. Now I've got about 18k miles on my ride and have seen almost no oil consumption issue from day one. So either:
1) Im lucky
2) the 2012s have fewer issues
3) I'm thinking that you drive you car pretty hard to have the much blow-by
4) am I missing something here....?

Also, Love the setup. Just some advice if it matters. The SS hoses seem to be sitting on top of your intakes? Over time they will grind the steel down if you don't have something between them...lesson learned from my last set up.

How did you break the motor in? Or did you not and it was a test drive car a few others drove first? How often do you change your oil? How do you know you didn't lose any? Do you measure before and after a oil change? Every car will have blow by, just depends how much so you will lose some oil over a period of time.

Power and consumption are directly related to break in...Break In Secrets--How To Break In New Motorcycle and Car Engines For More Power. If you're doing good on oil than I bet the motor was done right. Hell maybe nissan broke it in right on the assembly line testing the motor to full power. I know one of the Japanese bikes (Suzuki?) does this!!

Great point ... and one I recently discovered emptying the cans. Rubbed a swath of paint off the intake tubes so going to remedy that.

Don't recirculate the catch can fluids back to the oil pan, it's a bad idea. It's not just oil trapped in them, it's also blowby gas and other vaporized crankcase gasses, which means it's got a high amount of both raw fuel and combustion byproducts (carbon, etc) blended into it. Just smell it once when you're dumping the cans and you'll smell the fuel in it (and as noted above, it picks up a bit of water vapor too).

(Also: you'd be creating a vacuum leak and/or another PCV flow path if you hooked up open drains back to the oilpan, too).
