Someone smart explain this.

I like to think it’s not to often I’ll ask a newb question. But I haven’t built a car in 15 years. Been build race bikes until I about killed myself and the wife made me quite. Lol. So back when I built a 99 Camaro the intake consisted of a filter. That’s it. Already got rid of the stupid sound tube. Now someone explain this dumb vent system (I’m assuming). And give me the pros and cons to ripping it out. Options for a cleaner engine bay. I’m doing a full N/A build so any tuning or crap that would be needed is about to happen anyway. What can I do with this cheap plastic mess. Pics would be appreciated if any relocation shit occurred. Apologies for language. 14 years in the military and counting. It’s a part of me. Lol

a full na build will require a vacuum pump. you've already answered your own question.

Well getting rid of the sound tube is a no brainer. I would like to think I cleaned up the area around the air intake tube. Got rid of the bugle on top off the air intake hose with a different elbow. I put the return PCV tube under neath the air intake to hide that hose. I am going to get the relocation coil pack mod and different valve covers. The engine bay is to busy, I call it the octopus bay.

A blanket or sheet metal might work also. Lol

It’s all part of the PCV system. Your 99 Camaro had one too but it was much simpler back then. If you’re doing an engine build then I suggest you discuss options with your engine builder as part of the build process. Changing the system can potentially cause the computer to make the engine run too rich or lean.

Pro’s: you don’t have to do anything to the PCV system.

Cons: sucking oil into the intake tract.

As mentioned a vacuum pump will reduce crank case pressure & reduce pumping losses. The other, much older, method is crank case vent tied into the header collectors. But that is for cat-less systems as the straight oil sucked into the exhaust will wreak havoc on them.

Yea I still need to order my catch can and I’ve looked into that exact could relocation kit. Pity to stamp their name on top a motor without any of their products on my build lol except that one I suppose.

So if I’m not mistaken. The catch can install removes the second line coming off the intake tube. That helps the look a lot.

Anyone know if those lines being longer would be devastating to their performance. Because my idea is to run regular hose and route the hoses behind the engine on the firewall with all the ABS lines. There’s a ton of room back there

I just moved the hose that’s attached to the intake elbow that was original on the side where the MAF is. I put it under neath the elbow out of view. I have a Mighty Mouse catch for the right side of engine to clean the vented air into the manifold. I have a oil separater to clean the blow out side that is routed into the air intake elbow. The factory plastic filter for that hose is sub par IMO. I did run a breather cap on that side for a bit but changed it back to the same routing the engineers designed. Back in the days (1970’s) I would always just put on a breather cap on the valve covers. The new design is to prolong the life of the engine I am told. Makes sense. I like to fiddle with stuff that’s why I do it.

The factory set up is fresh air to engine comes in from air bridge to middle port, the 2 end ports to go to both valve covers. I have EliteX2 with clean side as well as dirty side filtering. I used the sound tube mounting for my catch can. The clean side goes from air bridge to driver side oil fill cap adapter with filter and then I just ran a crossover from each valve cover adding in the fuel line to the crossover tube. I capped off the factory clean side box as it drains into oil pan. I am not sure if you think this looks cleaner. I also removed all the covers ect. The most critical is the dirty side as factory set up goes from crank case directly to intake manifold. I use dual port to ensure there is a vacuum to evacuate crank case under full throttle as intake has zero vacuum at full throttle.

Excellent way you capped off the factory cleanside. We don't like ANY contaminants being returned to the crankcase as the stock one does, but even being plastic, it does work decently aside from returning it to the crankcase.

Our dual valve emulates a vacuum pump system and that is one of the features that put it heads above any other and of course trapping app. 95% of the substances you don't want ingested VS less than half the other ones do.

Allowing pressure to build and then vent is never good. So many advantages to doing to correctly VS technology from early 1900's.

Cheers!
