Catch cans







As far as cleaning your intake, it's probably not really necessary, but it wouldn't hurt either.
Just make sure you get everything buttoned back up properly.
To the people that use them...
but please do not tell the other 99.9% that we are harming our motors, because we ARE NOT. 
Whether you think a catch can is needed or not is your opinion, but to state they add no benefit is not true. They catch oil that would otherwise end up in your intake and over time will be burned in the combustion chamber, sent through the converter and out the tail pipe. Guess what is catching the burnt oil? Assuming continuous burning of small amounts of oil over time will not shorten the life of your converters is also wrong. My point is an oil catch can correctly installed has absolutely no detrimental impact on the life of the engine, but provides several short term and long term benefits that can buffer potential issues with the emissions system. I am absolutely sold on the benefits provided by catch cans and this was one of the first upgrades I completed on my Z06. By the way, I have already seen the proof they work.

I also unplugged the module above AND also unscrewed it (screw on the right). That will let you rotate that module and gives you a few more centimeters.
I could not get my hands/fingers down around those clamps to release them and get the ribbed tube off the intake/outlet for the catch can. After an hour and a half,
I ended up taking a hack saw blade. The blade has a hole on each end to attach to the fame. I grabbed the pastic "pin" sticking out of the clamp, pulled it back and up, and pop, the top hose came off. I then took a pair of pliers and a screwdriver. I pulled from the back and worked the hose back until it was straight, not a u shape. I could then rotate the bottom, outlet hose until I could see the same "pin". I poped it back and up and finally, I had the whole thing off.
Next step, the can. I got it on but am very unhappy with the look and installation. I tried a couple of places, but none of them really gave me any room. Right now, it's mostly under the plastic valve cover, and the bottom of the catch can is sitting on the some metal next to what I think are the heater hoses. I couldn't get the thing to fit mounted on the block. Right now, the bracket is in another hole, about 2 inches to the right, the bracket for the belt tensioner I think. The plastic valve cover is actually pretty hard down on the top rubber hose.
I've heard others have mounted them remotely, and I'd love to see some pictures of where others did. I think all you have to do is buy some more 3/8 hose, and I'll probably move mine at some point.
But, HUGE PITA with the LS3. At this point, not sure it was worth the effort. Time will tell.
Good luck

Does the elite catch can come with everything to install including instructions? best place to purchase? How much?
One unanswerable question is, does the oil from the crankcase help lubricate the valve stems and by reducing the oil, will that cause valve problems sometime down the road? We ran into this problem with unleaded fuel.
I have been meaning to contact EE to find out if they have engineered a different bracket for the LS-3 installation to make it easier to maintain. I've wanted to design my own and send it to them for fabrication but have just not had the time.
Bye the way, does anyone know where to get the unusual engine fasteners? Cad plated bolts and aluminum heads do not make a good mix. I removed one external bolt and it appeared to be plated, maybe by aluminum, certainly not Cadmium or Stainless Steel (another bad combination). It would be worth it to me, I'm OCD about stuff like that.

I have the base coupe but didn't like the "box" on the side of the air intake so I purchased the Z06 stock air intake. Worked great/looks great. I have the elite catch can.
