This is a catch can I purchased from CCA. This isn't the traditional mounting spot but it keeps the can further away from the engine hence it stays cooler and allows the oil to condense faster. When I called up CCA I was told this is where they mount the can on their race cars.









Here's the oil I drained out after less than 3,000 miles. Needless to say, I'm very pleased with my catch can!

Looks like it works just fine in that location.

I will be installing one very soon, that sounds like a very sound thory. I will try your Idea for my install also. Thanks for sharing it with the forum members.

Cool place to mount it

All you need is:
1) A longer hose, I think I got 8ft to be safe - auto stores carry them.
2) A nut to go with the bolt that will be supplied with whatever kit you buy.
3) A few zip ties to bunch some hoses together for a cleaner looks.

All you have to do is:
1) Drill a single hole in your radiator shroud.
2) Bolt the can to the shroud using the bolt that was supplied to you and the nut you bought (it may seem flimsy but once the hoses are attached they are rigid enough to keep the can from bouncing around).
3) Attach first hose to can, run under radiator shroud, measure up to where the other end attaches and cut, attach hose.
4) Repeat step 3 for second hose.
5) Zip tie these two together and/or to other hoses to keep them away from any moving parts.

SFL Dirver, Thanks for the info, looks like a great plan.

I like the way it looks there, way better than the engine side of the radiator. This is where I'll mount mine. Nice job and thanks for posting.

looks great...mine is going on soon...
Actually I considered the catch can for my supercharged 2001 but sold it before that happened...
...however, having seen the cup of oil I am now considering for my 2001 Z06...

Before I was a little unsure if I really needed one.
Now, I don't know why I never bought one the day I bought my car!
Sometimes I wonder how much oil actually passed through into my manifold before I got the catch can

Great pics of the alt. location mounting

thanks for posting, looks like a much more user friendly location to remove and empty.

I thought the blowback was only apparent on supercharged engines, so I have one on my Mustang to prevent the oil from collecting on the intercooler. I'm also considering one for my C5 now that I see the pics above.
Thanks for sharing

Here is a video someone posted on here a while back. You can fast forward to get the point.

It's almost unbelievable how fast oil can accumulate with aggressive driving.
After having one I believe every should have a catch can. Especially if you like to hit high RPMs on occasion.


Here's the direct link to the video

Great post thanks.

Mine is fitted in the original location and it's quite hard to empty. That looks like a really good alternative

Sorry to ask (I'm relatively new to the C5). What causes the need to install a catch can on the C5? Is it due to a design defect in the engine? Based on the OP's photos, it doesn't seem like you lose that much oil after 3000 miles of driving. Is installing a catch can really necessary?

DeeGee

It's not a defect; it was designed to work that way. The amount of oil depends on the individual engine, the settings and how hard you drive the car. It's always a personal judgement whether you want to catch the small amount of oil or burn it off. GM obviously thought it was OK to burn it.

I have an elite engineering catch can and this link describes the issue and answers your question:

Its a design defect of PCV systems in general. Most all engines could make good use of one. Intakes inherently suck up oil through the PCV system. The can catches that oil instead of allowing it to coat up on the TB and inside the intake, runners, valves, etc.
I still get some oil even with the can, very little, but the cure for C5's is the LS6 valley cover in conjunction with a catch can.

Cool place to mount, thanks for sharing!!

To add to what DeeGee and Nuke said, the PVC system is there to bleed off pressure from the crank case. The air inside the crank case is very hot and oil rich. The stock set up has the air bleeding off into the intake manifold. The problems is that you now are putting oil rich air into your intake and not all the oil will burn off.
With the catch can, air comes out of the crank case, into the top on the can where it can cool and condense. The oil droplets fall to the bottom of the can and the air exits through a second hole close to the top and continues to the intake manifold.
