let us hope and pray we ALL maintain a pressure differential favoring the intake manifold under all conditions!

don't even want to think of what a belch of explosive vapor into the crankcase would bring about...but that is precisely why we are thinking so hard!

believe most of us have paper air and oil filters we check and change at intervals--wouldn't we do the same for a paper catch can filter?

thus the clear bowls for them, i should think;

BTW, no less than Jegs sell a seemingly good copy of the Conceptual Polymer can, for about a third the price, making it very competitive with the E. E. models;

Dirty Howie

Let me try this again.

Michael, I'm glad to see we both like the EE can. Is it perfect, no. Is it good and effective and fit our motors, yes. On my C5 I used almost every can available. I had one in the PCV line as well as the fresh air line. I had a small paper filtered fuel/air filter following each one so I could visably see what was getting past the main can. I thought the EE performed best. On my C6Z it was the only can that fit properly. I also tried the RX and like you found it was too large.

I think your idea of pulling vaccuum out the top is counter productive. The whole idea is to give the oil a chance/time to coalesce on the metal lathe shvings and drop to the bottom of the can. Reversing the flow in my opinion would pull the vapor from the side right up through the top with little time for coalescing. The flow would be working in opposition to gravity instead of in conjunction.

I forgot where I got it and have since given it away but I had a can that was dual chambered on top with metal shavings. Inlet and outlet were both on top. So air/oil went in top throught onside of the chamber out into the tank and the up through the other side of the chamber. It was a very small can though.

I'm sorry if you feel that I was insulting you. You might want to go back and read your first reply to me, some might think that is quite inflamatory. In any event I don't have a problem with you so sorry if you took that personally.

The fact is that EE cans are quite effective and safe. This has been proven by hundreds if not more member here since the 10 years I have been a member including my self. Does that mean there are not MORE effective cans. Not at all. Let me know when you have tried one that works beter than the EE and fits under the FRC and I will buy it.

Just wondering, where's Ricky been. I Haven't seen any post in a while!

Dirty Howie

He is busy counting all the members who are replacing their stock exhaust valves. He told me he went to Staples to stock up on pens and paper to help keep track of all the guys who will be replacing the OEM valves with the new stronger heavier hollow soon to be tested and approved by Katech.


DH

I figured he was due for another side shift and was taking time covering tracks and buring earlier statements.

Dirty Howie

Well it goes with out saying that Ricky is more than capable of explaining himself so I wont respond to that.

Getting back on topic, do you have any catch can experience to share?


DH

Undy

I definately can appreciate your abstention.

Yep, luv my EE and no complaits what so ever.

But... I was thinking of drilling/tapping the lower side of the main body and installing a drain-****. That would make drainage so much easier.

Dirty Howie

You know, like I said before, I have a lot of experience with catch cans. I have had some with drain-*****. I don't like them and one of the reasons I like the EE is that it doesn't have one. Michael was talking about the limited room in removing the bottom of the can but it is easily done, sometimes just having to depress the heater hose slightly. It would be much more difficult to reach down in this same hard to access area and try to loosen and then tighten the drain-****. Plus you have to get a bottle to catch the oil as it comes out the tubing. This is much more difficult and will likely result in oil spilling. Thats my experience for what its worth.

You "figured" wrong. But then again, what else is new???? Weren't you the one up in arms about grinder marks??? If the PRC heads were so great, well then why are you planning a "side shift" regarding having Ferrea valves swapped out for the valves that they sold you??? :

Looks like you have a "side shift" planned there buddy.

Newsflash for you Undy. Don't rip on me, and I won't rip on you.

Deal????? :

I'm right here.

Undy

That was the guy that bought my heads, but I agreed with the crappy WCCH workmanship.

The hollow valves has nothing to do with me liking or disliking the PRCs. Those valves were not even an option at the time. If they were I'd have ordered them installed in the PRCs.

'06 Quicksilver Z06

I distinctly remember it being you. But then here you are ready to change horses upstream.

Well let's see what you had to say:

110% you say, huh. Yeah, right. Keep brown nosing. I don't know what you hope to "gain" from it, but keep brown nosing. Then why aren't stock sodium filled exhaust valves in your heads??? You most certainly had the chance to install a new set of stock heads, or even stick with your former completely stock heads, but you run PRCs. Why if you trust Katech so much???? :

Well then how can you say that trust what Katech says 110% but at the same time "not trust" the stock sodium exhaust valves which they unequivocally endorse?

You really should have left this alone man. But remember, you started it.

Or wait a minute....... would you have ordered titanium exhaust valves???

Titanium exhaust valves???? The truth is, you don't know WTF you want. And it shows above. But here you are in here attempting to criticize me for a "side shift" ????

You'd better check yourself before you wreck yourself pal. You really should have left this alone.

https://www.corvetteforum.com/forums...post1586504276

Where was all of this "trust" when they came out with the initial "study" back in 2008???

You see, I had said nothing to you. Absolutely nothing. Made no reference to you whatsoever. You opened this up.

Seeing as how we have you going from stock sodium filled valves, to solid SS, to contemplating titanium exhaust valves and now Ferrea hollow stemmed exhaust valves, to whatever is the flavor this month ........Maybe it is YOU who should have "covered tracks" and "buried earlier statements" Undy.

Undy

You win, I'm not getting into this with you. It/you are not worth the effort. I should have known that a joke on my part would spark a relentless multi-post attack on your part.

'06 Quicksilver Z06

What "attack"??? Why are you getting upset? I was just "joking" here too and along the same lines that you were.

I can't imagine why you seem to not like this same "joking" manner when it is applied to you.

But since you don't like it when someone refers to your apparent plans for your personal property as "side shifting", and you obviously have the right to change your mind/position as to what you ought to do with your own personal property/engine in the management of the LS7 valve issue as you see fit and based upon the opinions of those whom you trust, same as anyone else, I'll say nothing more, "jokingly" or not, about the matter and your own decision making about your own car, as that is your business. I apologize if my joking came across in the wrong way to you.

On another note though, I just removed my catch can today and found this.




I feel a lot better knowing that this didn't end up in my intake manifold.

Michael_D

The reason I would like to pull from the top, is to allow the vapor and oil mix to "drop out" when the velocity change occurs running into the larger area of the can. The vacuum would then pull from the top and the metal (or whatever they are) coils would serve as a secondary means to collect oil. Most would probably drop out prior to reaching the coils. This is how big knock out drums in industrial facilities work. Vapor is drawn in the side, pulled out the top. But this does assume that the little can at the top would not allow the vapors to enter anywhere but the bottom. It would have to be sealed. There would also need to be a really good filter of sorts on the vacuum side going to the intake. Maybe incorporate one of these polymer things that dreameagle is talking about.

I must have slightly different hose routing that you. I have one hose that is directly underneath the can. I actually wrapped it with some fiber tape to keep the can from rubbing a hole in it. It's not very convenient to unscrew the can. I have to push down on the hose quite a bit. Not a biggie, but if I were ever in hurry, I can see myself cross threading the can.

But yah, I like the EE can. The machine work on it is really top notch. Perfect, no, but that's an elusive rascal that I have not yet ever found.

The one other bitch I have, is the can stole the bolt hole I use for my wide band O2 meter's ground wire.... Dammit.... grrrrrrrr, and I had a really cool and handy wire set up with a soldered spade and everything.. The little annoyances in life are humbling.

Undy

I find it much easier to unscrew the two bracket-to-can screws so I can lift the can up to unscrew the bottom.

I was thinking about fabricating a new bracket that raises the can 1/2" to 3/4" to make unscrewing the bottom a little easier.

'06 Quicksilver Z06

Would have been nice had they made the can itself about a quarter inch shorter.

Dirty Howie

Well you could always reverse the hoses, test and measure amount of oil collected to see which way is most effective.

On my 08 and now 06 the hose postion is the same. I don't really have to push on the hose at all but it is certainly in very close proximity. Do you have the one long (approx 1.5 inches) washer that properly postitions the can away from the block?


DH

Dirty Howie

You will not be able to seat the FRC if you do this unless you cut it. EE did an excellent job of positioning the can via bracket alignment.


DH

Dirty Howie

True but the bigger the can the more the velocity of the vapors is reduced which is one of the factors determining effectiveness.

Its not like we have to empty the can every day
