Jeg's PCV oil separator

[Daryl LBZ]

They came with the catch can.

 

Yup. After I asked I found that out when I ordered one last night. Looks way better with the upgraded fittings.

If you guys want the numbers let me know. I still have the pkgs and they are from Summit

175 miles since adding it and no oil yet.

Better put your foot down a little more often

175 miles since adding it and no oil yet.

 

Thank you, That makes me feel better about mine. I think I have figured out why we arent getting even a film to come out yet.

 

If your catch can is not positioned perfectly "plumb" or straight up and down, a small amount of oil may fall into the corner of the can where it can't reach the drain plug and come out of the drain. Also, depending on how far in you screwed the drain plug, the opening of the drain plug may very well extend up into the can, so the oil would have to accumulate to the point where it is over the opening of the drain. Another thing to consider is that the mike norris can is pretty large compared to the small jegs unit, so it will take a longer time for the oil to accumulate.

 

If I am wrong about this, it could be a few things. 1. Our trucks are not passing any oil through the pcv orafice...YAY! lol 2. The catch can is leaking air pressure somewhere and the oil is coming out the leak instead of going into the filter media poo. Or 3. The worst case scenario really, the filter media in the mike norris can is not fine enough to trap and condense the oil particles out of the air and the oil is still getting into the engine. Honestly, my pessimistic side is telling me that # 3 might be the problem. The filter media in the mike norris can appears to be 2 peices of green 3m scrub pad cut into circles. I am a little doubtful on the efficacy of that media. By comparison, the jegs units has a very tight mesh screen and probably does a better job of trapping and condensing oil than the mike norris unit. Even though the jegs unit seems smaller and cheaper, the filter media does seem like a better idea.

 

I am sorry for the pessimistic post guys, but I gotta speak my mind. This does not mean I am not going to give up on the mike norris unit yet but I do have a suspicion about it. I will continue to keep you guys updated with my findings and thoughts on this.

Any chance the filter could be changed to a different type?

[Cowpie]

It is primarily the reason I will be replacing my Jegs unit with the Conceptual Polymer unit. Offers the same concept as the Jegs unit, but takes the filtration up a notch also. Plus a larger collector can or jar (buyer's choice).

I am assuming you are talking about the filter media? If so, I suppose you could find a tighter mesh or different type of media but then you run the risk of the media not being able to handle the conditions and either not trapping the oil any better or even worse, the media coming apart and being sucked into the engine.

 

I had read the conceptual ploymer paper listed on page 4 here but I did not know the author actually made and sold catch cans with all of the ideal features!!!! If I had known that at the time I ordered, I would have went with his 2" diameter catch can instead of the mike norris unit.

 

Now, to make anyone I might have scared feel better, a few words. First and foremost, I said in my last post that I have a small SUSPICION about the mike norris catch media. That is all it is right now, unfounded suspicion. Secondly, please dont take my posts as gospel. Sure you can consider me a competent and credibile guy and I like to think of myself as pretty smart but I am hardly an automotive genious or any type of genious for that matter. Not only am I not a genious, I am not even a pro-wrench. I have basically no formal automotive training under my belt but I was taught what I know by several trained, certified people and I do have plenty of experience turning wrenches now. Third, My truck does seem to be idling a tiny bit smoother now that I installed the can and I am sure of this because my RPM needle does not budge at all anymore! It is rock steady at 550 in park and it always did seem to fluctuate up and down a little before I installed the can.

 

Like I said, I am not going to give up on the mike norris can yet. I still need alot more experience and data with this before I say anything defintive. Right now, I think the Mike Norris unit is high quality and a good value. How well it traps and condenses crap in your PCV system remains to be seen. Worst case scenario for me, I will remove the the mike norris unit from my truck and install it on one of the my other cars that I am less concerned with oil consumption. At that point, I could buy a different unit that I think will work better.

 

Again, No worries yet guys, Its still very early in the game and so far I am happy. I will keep you updated.

Irregardless of the brand we are talking about, just about anything is better than nothing on this issue. The Norris can doesn't seem like a total waste. After all, a lot of folks are using them. Same is true for the RevXtreme cans. I will say though, that those cheapie cans sold on Ebay that are nothing more than a can with a couple of holes punched in them and fittings attached with no baffles or filtration are just about worthless for anything except being used as a paperweight.

 

The concept that Jegs and CP are using, unlike the other cans, is to have the crankcase gasses entering be propelled to the side of the container by a series of vanes. This gets the droplets to coalesce on the cooler container side and then run down to the bottom. The the crankcase gasses pass thru the filtration to get out the remaining particulates. The Norris and Rx cans are doing the filter idea first. But neither is using very tight filtration. But they can't if this is the first step when the stuff enters the can, as it will clog up very quickly. The paper that CP has on their site went into deeper detail regarding all of this.

 

If I was using the Norris can already, I wouldn't jump ship too quickly. Play it out and see how it does over time. I am saving up all of what my Jegs unit is catching during a complete oil change cycle. We can compare results and see how each is doing. I have put on 1585 miles since the Jegs got installed, and I have roughly a shot glass worth of oil it has caught. When I get to time to change oil, I will probably throw on the CP unit.

Well after doing a little more searching, It looks like we are not the only ones here who are experiencing some confusion about catch cans and how well they work. I also found several posts where guys are reporting very good findings with the mike norris unit.

 

Again, some more time and experience is needed with all of this. All indications point upwards though, we are at least headed in the right direction, regardless of what catch can you use.

 

Some testing:

This is a long topic but the author of the conceptual polymers posts here and talks about things, there are also good posts about the mike norris.

In this link, someone supposively tested several catch cans and found the mike norris unit to be the best, see post 4

Really too bad there hasn't been some sort of "consumer reports" kind of testing done where all the variables are equal and conditions of the testing standardized. It is not practical for someone by themselves to purchase every major catch can product and spend a few weeks in testing. Maybe Car and Driver or one of the other rags could step up and do one of those test reports on something like this. Unfortunately, we have a lot of theory being tossed around, with a sprinkling of anecdotal evidence that is not corroborated.

 

Still, just from popularity and the results some have gotten, the MN, RX, CP cans would all be excellent choices. I think it is almost impossible to truly know which is the hands down best one without putting them all thru testing from the Amazon to the Arctic, from metro city driving to wide open spaces cruising, under heavy load and light, and all the while, some device to actually test the crankcase gasses entering the intake manifold for oil contamination. In the final analysis, the "best" catch can will most likely be the one a person has spent their money on.

I never expected there to be anything after 175 miles. With what people are seeing oil change to oil change it will take some time to accumulate.

[Bad Bowtie2]

Well??

 

 

Any updates on these oil catch canisters? Are you guys (who've installed them) still filling up "shot glasses" of motor oil??

The Jegs unit has done pretty good so far, approx 2 shot glasses of oil in 3000 miles. I wanted to move to a better unit so I got the Conceptual Polymer dual filter unt. Just came in yesterday, so will bank some time this weekend to hook it all up.

[RyanbabZ71]

I will check at the next oil change in the upcoming weeks
