catch can importance?

[Scott@Bjorn3D]

I did not have one on for 25K miles on my L99. Put one on and would catch about 3-5 ounces every oil change. I put Seafoam in the gas tank at 35K miles and went from 22 on highway to 25 on highway. So it cleaned up some carbon build up on the valves that had happened in the first 25K.

My LS3 had a catch can on her since 500 miles. Would of been on there day of delivery but Mike Norris was out of town on tuning trip.

Currently only the V6's are/were DI, the L99 and LS3 V8s are not DI engines if that is part of what you're asking.

Guess I'm the guy who drives it like I stole it... I dump mine, and I went the cheap route off of eBay, every oil change. Just a couple weeks ago, I dumped mine and found about 1 1/4 cups worth of oil. Ideally, I would rather catch it before it gets sent back in the intake to "burn" up. And from the countless threads I've read all seem to have a great deal of info arguing longevity. For me and my ride, it's a definate must-have!

Important to me. Check out this thread. http://www.camaro5.com/forums/showthread.php?t=112367

As far as the cheap cans go, good luck with those. I tested three cans and while all caught oil tow of them also allowed oil to be pulled through and into the intake. Sure getting any can is better than none, but what is the point getting one in the first place only to go cheap and get one that doesn't do it's job efficiently.

Most of the people that tell you you don't need a catch can are the ones that have never hooked one up to see what it does.

Catch cans are absolutely not needed. The oil is sucked back into the engine because the intake runners, throttle body, valves, spark plug tips, and the tops of the pistons all need extra lubrication. Some oil even runs back down into the oil pan. It's the ultimate green energy concept of recycling

I'm sure the cans work but the cans themselves might have issues. Driving it hard when you first get the car helps a great deal with braking the engine in. Agree with Dave on alot of what he says. And really it's become more a camaro 5 push product. Remember who runs the site guys lol. VENDORS ?!?!?!

Interesting perhaps read this.. http://www.camaro5.com/forums/showthread.php?t=68744

A friend of mine didnt have a catch can and I did. When he took his manifold off it was not clean. Took off my manifold and it was very clean. We both had V6 Camaros at the time. I still do he does not. As far as V8's since the V8 does not use direct injection then there are ways of cleaning the engine other than a catch can.

I would just rather empty a can than go through the seafoam. Just easier I do my oil change and empty the can not so hard.

Sorry, I was trying to be sarcastic. I totally believe in catch cans.

Yeah, go ask the VW dealerships (Was it VW or Audi?) that are having to strip heads down so they can hand-clean the oil sludge off of the intake valves how important a catch can is.

so lets see if i got this right. the catch can is good for people that drive the car like they stole something right? if i drive my car normal i should not worrie about it?

I don't have one and don't plan to buy one. If it was that important GM would have designed one into the car. The only people that will try to convince you that it's needed are the ones that are making the catch cans.

I have talked to a couple guys that bought the catch can, they both have V8's. One said he hasn't seen a drop of anything in his catch can, the other said he had a slight film of oil inside of the can. To costly and not necessary in my opinion.

Absolutely needed on the V6, V8 not so much but can't hurt.

I agree. Some have 'seen' benefits from them and some haven't. I can assure you your car will run 100k miles without a moments trouble without one, with proper maintenance granted. Probably further.
There isn't a right or wrong answer and opinions are like a$$holes, everyone has one.
