Has anyone installed a catch can in a Z51 C7.
Have looked at several install info’s but cannot find how to get the exiting hose off of the hose jumper from the manifold to the throttle body. It is heat shrunk on and no indication if it is to be removed with a razor blade, heated and removed etc.
Any install info would be helpful. Considering the Elite as it looks to be sufficient since not tracking the car etc.

There are some threads on this in the C7 tech section. You may want to post this over there. Hope this helps.

I installed the Elite can a few weeks ago. Super easy to do and took less than 30 minutes, start to finish.

To remove the existing "jumper" hose, simply compress the tab on each end (they're fittings there, not heat shrink) with a pair of pliers and they pop right off

Ken, which of the Elite Engineering catch cans did you install? Pics?

Are you guys saying f***ing GM didn't fix the oil intake issue with their PCV on their FOURTH engine iteration? Geez, unbelievable. It's probably the only damn car in the market with this problem. Forgot to ask this question on my thread, but now I know. Not a huge deal in itself, but that tells me GM's quality control hasn't improved much. Will check out the C7 today, but am not going to skimp on quality just because it costs less this time.

Of course I installed the blue one! It mounts under an existing mounting bolt too..

Uhhhhh... oil vapors in the PCV returned air isn't unique to Vettes nor GM.....

Google is your friend

That's the same one I am planning to get (but with the black AN fittings and rubber hose finishers):

I'm like you

Installing mine this weekend.

Of course not; that's what the PCV is for. I'm talking freaking OIL in the intake, not oil vapors. The crappy GM PCV obviously allows oil dropplets, rather than just vapors. No other car I've ever owned accumulated oil in the intake. And at least on the dry-sump '12 GS it only took a few hundred miles, not thousands. Cleaned it perfectly, and it was soaked again 500 miles lalter, of easy driving (was breaking engine in). Hopefully it's at least better on this engine. And I'm glad to see the EE catch can is an easy install, and no need to remove anything like on the LS3 (Helmholtz chamber). If GM changed the crappy slave cylinder bleed valve, I'd be okay. Saw the car this morning, and it's miles nicer than my '12 indeed. So far so good .

I did the Elite Catch Can about the same time as Ken. After 500 easy miles it had about enough oil in the catch can to pour out. I'd estimate about 7 or 8 ml. Definitely more than I would've expected for such a short time and mileage.

Does not vapor condense out of the air when it encounters a cooler surface?

Whats the deal with this BS - why isn't this a factory added item, whats going on here ?

Brunotheboxer

And you call yourself a car enthusiast. What a joke.

Can you empty the can without removing its mounting bolt?

KenHorse

Yes. Just reach under it and unscrew the bottom.

rsvette12

And so what if you do not add the catch can ? - most people probably do not know about this

gthal

Lots of cars benefit from catch cans...

Premmer

The can you installed does address the valley area but on a base model both valve covers are individually vented into the air intake tube and may contribute to oil vapor entering the engine via the throttle body; wonder if any base model owner has or plans to add additional cans?
