Jeg's PCV oil separator

[Jsdirt]

Ok finally got some real world experience with this thing.

 

The first trip was 3 miles - in that time, the glass was fogged up - like a bathroom mirror after a shower (a little more wet than that, but you get the idea). Was 100% vapor/moisture.

 

Second trip was 615 miles. Half of that towing approximately 6,500 lbs. through mountain roads. I checked it the first time I stopped, and it was about 1/4 the way full of milk (oil and water mix). Every time I checked it along the way at fuel stops, that level had not changed. It seems to me that all the moisture that your going to find in the container happens as the engine is warming up.

 

I definitely expected to see more oil in there. So, in my instance, it's burning it instead of puking it out the PCV. Used about a quarter of a quart on that trip. I took it easy - shut the cruise off on hills so it wouldn't sit at 5k for 10 minutes - that cuts WAY back on the oil consumption.

 

Anyway - here's the pics:

Emptied mine after 450 miles, looks like its doing about the same as the Jegs. Kinda early to tell...mine was mainly oil this AM as most of those miles were highway.

What do you guys do with all of the stuff that accumulates in the jar?

[Jsdirt]

I dump mine in my waste oil burner bucket. It's a home-built one, and burns anything ... even antifreeze.

 

Before I built that, I'd have put it in an old cast iron frying pan, mixed in some stale or contaminated gasoline, and set the Mapp gas torch on it.

[sdeeter19555]

I simply wipe mine out with paper towels and throw it in the trash.

[Jsdirt]

That'll work too ... but I'm the cheapest bastard on the planet ...

The paper towel trick works when you're out of town...you can empty at a gas station while fueling. No worries about where to dump a liquid.

 

I actually need to empty mine, kinda been a stressful week and I forgot about it. Have about 700 miles on it.

I installed an Elite Engineering can on my truck with 1500 miles on it. Below is a picture of the product collected in 200 miles. It is mainly driven about seven miles to work and back with short trips in between. The throttle body was pulled when the can was installed and oil was pooled in the bottom of the intake manifold. No wonder there is such a problem with valve coking. The can was installed behind the left headlamp to get it away from engine heat. Works like a charm. This is my third Elite can and I would recommend them to anyone. Very high quality and great customer service.

I have skimmed through this entire thread LOL. Just a couple of things that are of concern - Someone asked if there were any warranty issues concerning the reengineering of the PCV circuit - while it would be a BS move yes there can be - the emissions warranty can be voided because you are modifying that system.

I have noticed a lot of moisture in some of the collections being confused with oil -the lighter the gray the more water less oil you have and you need to warm those engines up more and quit short tripping - those short trips will kill an engine more so than the oil you are trying to trap - sludge will build up in that motor from short tripping. And the last thing the design of some of those "catch" tanks imho would necessitate a vacuum guage to ensure you are not creating a resivoir for the vacuum in case a line were to get plugged or some other internal failure. Also what is being done for backfire protection on these designs - I have not saw any that I can verify.

Diesel engines and PCV recirculation are a mess all in themselves as most are pre - turbo reintroduction and create all sort of issues from contaminating the charge coolers to caking up the turbo.

I am pro catch can btw on DI/CRD but just want to make sure everyone is given correct information.

When you live in a cold climate, no amount of driving will eliminate moisture in the catch can. The pics I posted a few pages back of my can were from March - temps still in the 20's. Always had more water than oil, even after a 600+ mile trip hauling a 5k lb BMW SUV. Just the way it is.

 

Now that we're inthe 70's -80's, there's no moisture at all, unless I start the engine to move the truck out of the barn for 3 minutes.

As with anything, it is in all how you word things. To one person it might be consider a modifying the system, to another it is simply adding a filter to the system. No different that adding a bypass oil filter to a motor or another inline filter to the fuel system. Neither of which is putting warranty at any considerable risk. And for those that have enlarged paranoia glands and worry about issue like this, a catch can can quickly be removed and everything put back to stock in only a few minutes before taking vehicle still under warranty to dealer for service work. I can have the entire system back to stock with only a flat tip screwdriver and a few minutes of my time if I wanted to, with no indication to any service personnel that I have ever used a catch can.

 

On the back end, I can have the entire catch can setup fully installed and back into operation in a few minutes and the same flat tip screwdriver.

 

I used the same catch can setup (the Conceptual Polymer standard and high efficiency installed in tandem series which replaced the Jegs early on) on my 2013 5.3L in a 1500 and now on my 2015 6.0L in my 2500. Year round in upper midwest winter cold and summer heat. Nary an issue. Just that in winter months, it needs emptied more frequently because of the increased condensation capture.

 

A side note: while the 5.3L was a champion at shoving oil thru the PCV line, the 6.0L also has the same problem, just not as severely. Only about half as much goes thru the PCV tube on the 6.0L, but it is still enough of an issue that I am content to use the CP catch can on it.

I'm old and miss a lot of stuff, so I thought I'd mention this thread and source over here.

A little mod for filter material and maybe a petcock drain and you'd have a pretty good can for not much money.

But then..........

Another update, My mike norris catch can is still working well and it is has been a few years now. I did clean the filter media with 91% alcohol 7,000 miles ago. I drain my can every 2,000 miles and I get about 2 ozs every time I open it. I have the 4.8L V8 and it is not burning any oil between oil changes.

Its not messing with the lube system, and the camaro LE does come with one from the factory (dealer installed)

 

Feel free to do some reading on the subject, explains it pretty well here:

Correct. The 1LE has for several years, and now the Z28 and others.

 

As for the Jeg's home air compressor user, those are less than $10 at Harbor freight, but they only trap a small amount letting most pull past so with a GDI engine it will not help. You also want to add the secondary outlet evacuation suction option on some of the others that are good and effective like the Elite E2-X dual valve. This then improves the OEM PCV's function giving suction when under acceleration and at WOT as well.

 

Good your doing something though!
