Anyone NOT run with a catch can?

[TX/ZL1]

Sent my car up to ADM in September to have Andy install the 750 package. Based on all the comments on this forum that you'd have to be crazy not to have a catch-can, I asked Andy if I should have him install one while he was doing the other work.
He said, "Absolutely not....don't need it....don't do it". That was enough for me...

I'm kind of wondering if the ZL1 didn't need one then why did GM put one on the Z/28? surely it would have less crankcase pressure. Did they do it after all the debate and all the appearent forum member need? Does GM read this forum? This has been discussed at length on here many times and was said a cc was a must have and why didn't GM just do it at the factory, and now magically the Z/28 has one from the factory. If the engineers in the post above said it is not needed then why now, I know there two different engines, but blow by is blow by right. I put one on my car only because of all the said need on this forum, I wasn't going to do it because I assumed that if it really needed it it would of been there, but engineers and manufactures make mistakes too.
It didn't affect the performance, but maybe gave me piece of mind that a quarter cup of oil wasn't being burned, and the build up collecting in my cylinders and on my valves and or collecting on our already compromised
intercooler brick.

Well put it another way...if the CC is not hurting anything I'd say it cheap insurance for less than $200 to protect the longevity of your engine...

We spend more on gas in a weekend driving these ZL1's vs. the cost of a CC. lol

Just my .02

That's just the thing, it doesn't protect the longevity of anything according to the people that built the car lolol

Bryan ....
Curious about those few who have blown a seal (w/o a can) ....then installed one and have had no more seal issues.
What do you contribute this to? Coincidence? Non-related issue? Another seal blow coming soon? ....other?

Seems as you know a bit about this MOD curious as to your opinion. One of the reasons I went the direction I did was to prevent POSSIBLE issues ... no harm in CC vs. factory correct?

Is added BOOST a concern with factory set-up? Would you give more weight to a CC if boost was added?

thx

^^edit^^

I do see you have added boost ... (still w/o a can?), have YOU had any leakage problems?

I've yet to see this CC on the Z/28, all I see is the big azz oil tank ...

So that large can is just for engine oil? very interesting. I see a dip stick and a oil cap on it, maybe someone that knows can elaborate on it's purpose.
None the less I really don't think for the money you could go wrong with CC on the ZL1 plus it might just might keep the top end a little cleaner.

Yes, the LS7 uses a Dry Sump oil system, not a wet system with oil pan.

Z/28's do not come with a factory catch can....

I think you're missing the whole point of the benefit of a catch can. It isn't going to show any value in just 8000 miles... It is a long term investment, since the issues theoretically caused without one are long term, not short. Just an FYI. I bought mine, a brand new Apex, from a guy on Ebay who for some reason bought it and never used it. I paid a hundred bucks. Pretty chea insurance, if you ask me. One could easily also argue, "I don't need to change my oil, there's still plenty of it in there..." (I actually heard a guy say that once) - sure his car kept right on running, but I doubt it's still running as well as any of mine today.

Are we talking about the 1LE Oil Separator kit from Chevy?

Camaro 1LE PCV Oil Separator Kit
October 2, 2012
The increased handling performance of the 2013 Camaro with the 1LE performance package can generate some off-road or track conditions where engine oil can be ingested into the air cleaner through the fresh air tube that connects the port within the right valve cover to the air cleaner. The Chevrolet Performance Positive Crankcase Vent (PCV) oil separator kit can improve this condition. It’s a standard part of the 1LE performance package.

The kit (part number 12653073) is included with other packaged components in the vehicle. It should not be installed during PDI at the dealership. The kit and instructions should be kept in the car. Owners are responsible for installing the oil separator in the car for track use.

The kit is designed for off-road or track use only. The production PCV system should be installed back on the vehicle when driving on public roads.

The kit is not designed for winter driving conditions (ambient temperature should be above 32° F, 0°C).

Kit Contents

The PCV oil separator kit includes:
• Main housing (Fig. 7, A)
• PCV cap/plug (Fig. 7, B)
• Connecting tube (Fig. 7, C)
• Instruction sheet

No, I've never had any leaking issues out of mine. A catch can is only going to catch some of the oil vapor to keep it from going in the intake. It's not going to vent anything. If you want to vent the crank case you need to do it at the valve covers. That's the only place where you could get enough venting to actually help under heavy boost.

I think everybody is confusing two separate issues here. One issue is catching oil vapor to keep it from going in the intake. The second issue is venting crankcase pressure under WOT conditions. Two different problems, two different fixes. To catch the oil vapor you need the catch can. To vent excess pressure from the crankcase you need a breather on the valve cover.

Yes maybe this is what I was reading about. Is this a fix only for the 1LE
or could it be used on all LS motors.
