Engine oil catch cans?? **UPDATED** see my last post
 

I keep hearing about people installing these engine oil catch cans, does this motor burn oil that bad that this mod needs to be done? I did install a catch can in my 2000 Z28 way back 13 years but the LS1 motor was notorious for being an oil burner.. If this is a needed mod to do, where can i purchase it at? Thanks

Vacuum lines go from the crank case to the intake manifold. It will help keep crank case oil out of there but that's about it.

iS THERE A KIT TO BUY SOMEWHERE? i saw on aam's site a very nice kit to buy, but 500$ thats just crazy. ( http://www.the370z.com/diy-section-d...cans-370z.html ) I would love to buy that setup....

Where have you read that people run catch cans on these cars? I've heard about it for the boosted folks but for a normal N/A car, I really doubt you'd benefit from running one.

its beneficial for a NA car and a boosted car.

During normal operation of an internal combustion engine, there’s a compressed air and fuel mixture inside the combustion chamber that is ignited and as a result, forces the piston down. A small amount of that ignited mixture leaks past the piston rings and ends up in the crankcase. This leakage is often referred to as “blow-by” (leakage past the piston rings), as well as oil mist.
Some of the oil mist and other products settle along the engine intake and over time form a “gunk.” The oil catch can collects the oil mist and condenses the fuel vapors while allowing “cleaner” gases to be passed back into the intake.

It will keep your engine a lot cleaner.

I know what blow-by is. I'm just saying the cars are designed to run like that from the factory so I seriously doubt you will see any benefits from running one on a lightly modified Z. Money can be better spent elsewhere.

For a NA 370Z engine, a catch can is not really needed. As per EVOHUNTER's great explanation, it will help keep the insides a little cleaner, but that shouldn't be a problem with a NA DD.

But, if properly installed/maintained, it won't do any harm. Go for it if it will make you feel better.

Not everything from the factory is good as is (fuel tank, CSC, steering wheel lock), you are right there is little benefit to it but it can help keep things like TBs and other parts of the intake cleaner and less loss of power over time. 500 is worth it for a show car, but really one can just get a generic catch can system and mount it somewhere, there should be a DIY if you google search. They are "cheap" and easy to install.

Our engines have two oil/air separator from the factory. They are located above the valve cover and connect the valve cover to the intake.

An aftermarket catch can will have a small benefit of keeping the throttle bodies a little cleaner, BUT they still will need to be cleaned.

Keep in mind: if not installed properly they can introduce an un-metered air leak.

guys, i know what a setup like this does, and i understand a pcv system.. I do not want to come off sounding cocky by any means, but can someone point me in the direction of buying a setup or does one not exist as a "kit"... i appreciate y'all

Where did I say you didn't know what blow by is? smh.

Only posting to help others understand what it does, and how its beneficial.

My z06 was stock, I had problems with the runners building up with crap, catch can solved this, its all over the z06 forums. Just because it was designed from the factory doesn't always mean its always the best.



theres not really a kit beside AAM, just buy 2 mishimotos, they have Lifetime warranty if they leak.

Mishimoto Compact Baffled Oil Catch Can, 2-Port, by Mishimoto

I bought 2 of these.

Saikou michi makes some nice stuff.

can i buy 2 of these and make them work? S1 350Z OCC Page

little update... I reached out to Saikou michi and i have their custom made to order dual tank setup coming. Pretty happy about this purchase. Wasnt to expensive, will be very benificial, and will have a nice appearance when hood is open as i ordered them with red powder coating with white labels! Said it will be here in 7 weeks, as they are seemingly very busy this time of year, at least that is what i was told. Here is a pic of what their dual setup will look like..

Might be a really stupid question, but is a single or dual catch can setup needed our motors?

dont think anything we do as enthusiasts to our cars is "Needed" but we have these cars to tweak them and do upgrades too. So, needed..... no, not really, but will it hurt anything, absolutely not :tup:

Going the custom route.... Sumn similar to this one...

i ordered the saikou michi 370z oil catch cans too.. i ordered it around 4 weeks ago and i was given a 5 week estimate time before i receive mine.. looks promising and i cant wait to get mine!

How much is it for the 2 from Saikou Michi? Any discounts for forum members?

updates about the kits?

He doesnt have them on the site yet.

i would check this guys stuff out too, I actually have one of his cutom coolant tanks on my car, and he makes coolant tank/catch can combos.

Great quality and very good customer service from him. You'll notice my alpha air/oil separator on there w his coolant tank.

But why would I want to run my oil vapors and PCV through my coolant tank??

Sarcasm just in case.

I love the way your setup came out I just haven't decided if I'm going to do catch cans yet as I haven't seen any oil usage at all in my system (like not even a little) so I'm not really sure how much of any oil I would capture in the cans if I did it. If I do in going your route, plenty of space since the intakes are gone.

Thanks bro!
Well its for preventive maintanance so that decision is up to u. In my case before i upgraded i had some small jegs catch cans on each side. Draining them became tedious and annoying af. But then again i am boosted. I got myself the alpha air oil separator for the gtr and bad it retrofitted. I dont have to drain anymore w this one.
I just wanted to make people aware of "admintuning" and that he can create custom coolant tanks and catch cans at your desired measurements.

FOrgot to update this thread :icon14: Got the kit in the mail awhile ago and finally got around to installing it a few weeks back. Fitment is excellent and the quality of the tanks and powder coating are 2nd to none! Ill upload a pic of the install... nothing fancy but gets the job done

Did you install yours on the crankcase vent tubes (rear) or the PCV tubes towards the front?


Sent from my iPhone using Tapatalk

the catch can can be used as single, but usually prefered as dual, on the single you need Y connectors, cuz u have 1 catch can and two intakes.

this mod here on N/A engine only good as preventetive maintenance so your throttle bodies dont get gunk stuck to it. And you dont have to clean it so often.

i dont want to sound like a bad guy, but those intakes are no good, they draw hot air temp from the engine bay, causing power loss and faster overheating.

Are they compatible with the stock air boxes?

I would say yes they are, but don't quote me on that, it does seem to be installed out of the way.

I have catch cans on my turbo Veloster but not on the Z. Boost makes more blow by and crankcase contamination + direct injection and I have been shocked at how much the catch cans have collected between oil changes. That said, when I changed out my intake manifolds with the Z1 400HP ported manifolds, I was very and pleasantly surprised how clean the ports and intake vales were, quite pristine actually(32K miles). So I think they really are not needed on this car in NA configuration. Also, I have tracked this car so again, quite surprised how clean everything was. Will they hurt, no and they may help to some degree depending on the age of your engine and how you drive. Your mileage may vary.

mine are almost full after only a couple hundred miles

Considering the 370Z is port injected in both NA and FI, skip to 2:33 of this linked YouTube video. There are all of 10 seconds to describe an oil catch can for port injection, vs 10m56s for direct injection. Really just adding weight.

In the esteemed words of Lil Dicky, “$ave Dat Money”

I installed the ADD-W1 dual catch can kit at 37k miles and at 39k the driver side can had a little over an ounce of oil goop that registered on the built in dipstick - not much but glad it didn’t get put back in my intake.

I've recently added this to my 2014, but the hood does not shut correctly. Off about a half a cm. Did you need to do any modifications to install? I have factory air boxes.

That EE guy is an embarrassment to engineers. He doesn't know what he's talking about half the time and mixes facts with outright ignorance to sound more intelligent then he actually is. He lost all creditability when he said that resting your hand on your shifter will damage your transmission. On port injection fuel does pass over the intake valves, it is no where near enough to wash and clean them from oil vapors from the crankcase. Nor is fuel going over important components like the throttle bodies that can gunk up over time.
