I need a catch can, maybe you do too.

From what I read they all have the same purpose .
Thanks in advance .

Apparently there is a pretty big difference in how much they catch. Not sure who can independently validate that..

Thanks!!

Just remove your air inlet tube and then the throttle body, 4 bolts and a wire, then look inside with a flashlight. depending what you see, go from there.

Seaform is da Bomb! My Dad just went and got a can for the Camaro, taking Car to IPS Friday for the Install in my Sig.

Insane! That does not seam right? Is the valve cover bad?

The more surface area you can run that dirty air over, the great chance you can get the oil to condense/coagulate before the air moves one through the can to the intake.

You can go from a completely empty can with an inlet and outlet, but that won't be as good as something that has at least perforated plates that the inlet air has to hit and go through before that air then gets push out the outlet.

The RX can seems to "mist" the air out a perforated tube that then hits the sides of the can and then has to pass through a perforated plate at the top before going on out to the intake.

It seems the trick to seeing how well your can works is to put a filter inline between your can and your intake. If there is an oil charge still in that air, you will see it on that filter.

LOL!! The oil in the intake air charge reduces the amount of useable octaine in the A/F mixture thus less energy is released pre explosive event. This on a brand new motor thiscauses detonation and the ECU will pull timing to protect the engine, the result is less power and porrer fuel economy (the idela A/F ratio with the most timing is where the motor runs the most efficiently).

Over time, the "gunk" deposits that buld up on the intake valves reduces the volumetric efficiency of the flow (velocity makes power, power = effiency) further degrading prformance and fuel economy and the carbon build up on the piston tops and combustion chamber as a result disrupt the burn pattern and effectivness of the quench areas causing hot spots.

Then, long term these baked on carbon deposits begine to shed particles which get trapped (carbon is diamond-like hard and very abrasive) between the cyliner wall and rings/pistonscausing scouring and shortened engine life.

Now I would LOVE to have anyone who thinks this is not an issue post up your automotive engineering background and explain in detail how this oil ingestion is anything BUT harmfull in every way. Just ONE positive. I'm all ears. I have only beed building race & performance engines, designing products for the aftermarket performance market, and racing professionally for over 35 years training at some of the most respected engine builders doing R&D for GM, Ford, IRL, etc. I'm all ears.....

Can we now end this for the naysayers. Buy one or dont.Your choice

If this is such a horrible thing for the engine, why is it built and sold the way it is? There are 10's of thousands of Camaro owners who will never read an online forum and will drive their cars never worrying about this issue. So if it is so harmful then why isn't it corrected by the factory? Recall? Class action lawsuit?

Point I think is in the normal term of a car buy, and your right, most will never know or care, it may not matter but in the long run, and I keep cars long time, it can. You may never here the pinging or maybe loss of power so They figure it wont matter. the closed pcv systems cause all this on maybe all cars? Some worse then others.

Your call.Were performance folks here so we know about all this stuff.

Because it is a slow, slow degradation of the engine internals and the average person isn't going to keep the vehicle around long enough, or wouldn't notice the issues this brings long term (would just blame it on engine wear and tear/age), and they also know that this would be one more maintenance item that the public is not generally prepared for (shops or individuals that do their own work). It is not a safety item either, just a long-term engine longevity thing, which would fall well outside any factory or extended warranty.

Plus it has been this way for a VERY long time on just every single vehicle, I would expect. I am sure some engine designs generate more or less than the camaro overall as well.

It takes alot to get a class action suit against a manufacturer. Don't get me started on the oil sludge issue and resulting engine seizure of the first year 2.7L Dodge magnum motor design.

Think it's been covered already...:bangdesk::bangdesk:

I have one so I am a fan.... but the car was designed just like all other new cars to be burned off with no issues... so it not a nessesity to have one and the car will still last a very long time with no issues, I have one for 2 reasons I like the looks... and its just to help with the burn off of the oil and I am sure its not 100 %. my point is only that all new cars are desinged to for the oil to be burned off with no issues. I am sure if it was a must have it would come with it..

$100-150 to make sure that across the next 100K miles of ownership, I won't be running at least a quart or 2 of dirty motor oil through my intake and into the top part of the engine, I am good. Less build up, and the air/fuel charge is cleaner as well in everyday execution = a win in my book.

[SC2150]

Teamspeed also nailed it. Millions out there are driving their cars and light trucks with never knowing it is an issue. It is a gradula degredation and not noticed. BUT, go to your dealer or other service center and they are sure to reccomend an upper induction service.cleaning (SeaFoam or similar) for $150-$250 to remove this gunk and restore your cars "peppy-ness & improve MPG". (most good catchcans are that or less). Shell, Mobile, etc. advertise their fuel additives to help prevent the "gunk" build up and show intake valves after just 5 k miles all crudded up. The worst offenders I have seen are the Kompressor I-4 Mercedes for FI cars, and the new Mini for DI motors. Ask a Mini service tech....they are pulling cylinder heads off to manually clean the buildup (DI motors inject the fuel directly into the cylinder so no fuel swirls past the intake valve to help keep it clean and deposit free) and or do valve jobs at 30-50k miles!!!

You cant blame the automaker...they have a tough balance between what is best, and what the market can bear. When I talk to the few I know it is a common frustration that even a great improvement in a design or an additon that may only and $23 or even .20 ents gets shot down in the big scheme of things.

If 99% of the buyers have no clue its an issue why in the world would they put the expense into a solution?

For most a car is what looks nice and gets them from point a to point b. Heck, we have 2-3 generations now raised to never even think to check their oil!!

But for those that love their baby and want the best, there are forums like this to learn from.
