If someone want's to purchase something because they believe it benefits them, they will. Some people drive their vehicles hard without getting into swapping cams,etc.so it would probably necessitate having one. If you agree that it is of some use, what's with all the negativity of your posting? It's seems to me that it works especially well for those that drive "spiritedly" as evidenced by the photos shown above. For all you racers, it may be a concern, but who cares, you are always tearing apart the engine swapping cams, etc., ha. This is from another posting, seems catch-can sales must be down.go figure.įrom a write up on the LS3 engine, from the horse's mouth, and yet more proof why a catch-can is worthless on these type of GM V8's.so for those of that don't race, the system as built from the factory works fine. As always, if you have questions regarding this or any topic the crew at Apex Motorsports is more than happy to answer them. Apex Motorsports catch cans are designed to be the best functioning catch can for Camaro owners but there are a couple other good options as well. Be sure that the can is designed with an effective internal filtration and baffling system to pull the oil vapor out of suspension. These will capture a small amount of fluid but the vast majority passes straight through and ends up where you don't want it. Cheap catch cans (less than $100) are plentiful but they are often little more than an empty can with two ports. When it comes to selecting a catch can you will get what you pay for. The other gases are allowed to pass through so that they can be burned of as intended.įluid captured in catch can after 800 miles As the droplets form they drop harmlessly into the bottom of the reservoir so that they can later be drained. As the gases and oil vapor enter the can they typically pass through a screening mechanism that gives the oil vapor something to adhere to. The LLT and LFX V6s in the Camaro are both DI engines as is the new LT1 in the C7 Stingray and all of the new LT based GM truck engines.Ī "catch can" is an aftermarket device that will condense and collect the oil vapor before it has a chance to reach the intake system. As you can see in the diagram below, with Direct Injection fuel is introduced directly into the combustion chamber. As automotive manufacturers continue to adopt Direct Injection (DI) technology in their now engine designs, any benefits that previously existed due to fuel washing over the intake valves will be lost. Going forward this carbon build up will become more and more of an issue. This can lead to a variety of issues including carbon build up, retarded timing, detonation, and power loss. The problem is, over time the excess oil vapor collects along the inside of the intake tract and forms a "gunk". The PCV system vents these gases along with oil mist from the crankcase and routes it back into the intake manifold so it can be burned off. During the combustion process a small amount of gases leak or "blow-by" the piston rings and create a positive pressure in the crankcase.
One of these is called the Positive Crankcase Ventilation (PCV) system. Modern engines feature a variety of emission control devices and systems to reduce the toxic gases released into the atmosphere.
