Oil catch can, anyone running one?

As the temps drops I'm wondering if anyone runs one on a stock v6 and if its worth getting. I only question running one because I noticed I lose a little bit of oil between changes in the colder months vs warmer. February this year I did an oil change and drained less than 5 qts which I found odd.. Since then I've done 2 oil changes with the weather being much warmer and drained over 5 quarts.

The truck doesn't burn or leak any oil and I do 5.5qts of 5w30 f/s mobil 1 every 5,000mi.

 

Well…..there are many examples of the 4.0 running huge Milage without any issues. So I don’t think we need them.

However, there are people who run them, and between oil changes, they collect about 4-5oz of blow by in their catch can……so it’s doing something.

but for the most majority, we don’t run them.

 

Plenty do. I don't have one but am installing one soon. It can only help imo

 

peace of mind kinda thing for me which is why I ask. I was fairly concerned when I noticed how much oil went missing on that oil change but I don't think much/if any harm was done. I just didn't want to look like the knucklehead installing something that is useless lol.

Let me know which one you go with and when you do it; maybe can plan a day and do them together.

 

So I am running the ripp supercharger catch can and I love it you can tell as to whether you are getting any trash in the blow by or not which to me being a technician for a boat company and working on so many engines it's a plus for me. There are alot of high performance boats that run them so I have had experience being able to see how they work. My last vehicle I had was an Audi A4 turbo swapped and tuned and had a catch can on it and worked out perfectly on it as well.

 

I run an oil catch can. You can see my latest results between oil changes here: https://www.tacomaworld.com/threads...en-tacoma-today.6499/page-11891#post-28159125

I'm in a warm climate, so I don't lose too much oil.

On one end, Toyota didn't find it necessary to install one and our engines are very reliable as-is. You should be fine without one regardless of the climate. Most people don't run one and, of course, some find it useless.

I had one so I installed it on my engine and I plan to keep it there. The oil that I catch would've gotten burned up in combustion, but keeping it from being burned, I would think, keeps everything cleaner.

 

I installed a Saikou Michi catch can. But, I don't see how a catch can will help the OP’s issue of oil burning in cold months. A catch can removes oil and other contaminates that get recirculated back into the engine via the PCV line.

Does OP drain oil with engine cold or warm? If cold, that may explain draining less in cold weather as oil flows slower in colder temps.

In cold weather you’ll get more blow by. I live in New England and I’m up early so the truck sees single/teen temps often. I don’t have any issues of oil loss in the warmer months as I just did an oil change (and have done for the last 100k) and well over 5 qts came out.

 

I still don't see a catch can helping you much, if at all. Granted, it never gets below 40 in my area … my catch can collects about 200ml every other oil change, and that includes water in the chocolate mixture. Give it a shot, if installed and drained correctly, a catch can only help an engine.

 

I have one. 2005 with 180k mi. A couple ounces of oil mixed with water, mostly water every 2k mi.
Do you need one? No. It does help, if only a little. If you're only getting a little blowby, your engine is probably running OK. Generally speaking.

 

The stuff in most NAd catch cans is going to be 95% water which will burn without issue and cause zero harm. Don't believe me, empty your catch can into a beaker, put it on a hot plate set at 220deg to boil off the water, you will be left with minimal actual oil blow by (unless there something actually wrong with your motor)

Catch can on NAd motors is not necessary.

 

Yes and I kind of regret it. Smog test shops don’t like it and if it fills up it can hydrolock the motor at an angle. Though that would take a while to fill up.

mine really doesn’t catch much. My intake is already dirty. I don’t care if it has an oil film.

probably better need on a turbo motor.

I got it because my commute used to be like a mile. I wanted to catch water condensation (milky color) but is no longer a mile. (Moved)

 

Keep in mind, all manufacturers have some kind of oil/air separator built into the pcv system already, usually in the valve covers near where the pcv hose attaches. There will be baffles built into the underside of the cover that's supposed to let the oil drip back down and the crankcase vapor go to the intake.

Volvo builds their separator into the oil filter housing on the side of the block. They're plastic and like to crack and suck air, setting lean codes

BMW had a mess of hoses under the intake on the older 6 cyls from the 90s and 2000s. Plastic separator, rubber hoses that would split and leak, fun times

 

Being that our Tacomas are not direct injected there really is no need for a catch can. They may help a little bit on a purely DI motor but even then the jury is out.

 

I've been thinking about installing one but what really do they save? I'm not asking this to be critical of those who have them because I was seriously considering it at one time.
If you were to perform a post-mortem teardown of high mileage failed 4.0, 1GR-FE engines, (I say high mileage because low mileage failure would indicate a different problem), what would be the point of failure?
The primary benefits of a catch can as I see it, are cleaner intake valves and cleaner catalytic converters. How much failure or how many problems do we see because of that?
Again, not being critical, really curious as to what the true benefit is. My KDX likes a little oil in the combustion mix, lol.
The older engines just vented this crap to the atmosphere but few of them ever went 300,000 miles. Maybe this extra, internal lubrication is a good thing???

 

They become more important on high performance (boosted) motors where blowby is just part of the game

 

I believe this is 100 percent true...On a GDI it is a different story.

 

I wouldn’t care enough to run one on a n/a Tacoma.
That said, I put a supercharger on recently, and was surprised how much had come through the pcv valve in a short amount of time, so I put one on. Figure that mix of oil and water wouldn’t be good for the supercharger rotors and bearings.
