Minor performance mods help.

Dumb question: So do you guys install these catch cans on all of your vehicles or just these GM trucks?

Think you can do it on most vehicles. Especially on turbo charged vehicles.

I just became part of a Jeep Forum and some of the people there said that it didn’t do much on the little 2.4L NA engines, but they also suggested on turbos.

My previous car Lexus IS300 (GCC spec - sold as IS350 in the US) had a 3.0 engine, I changed the PCV once. It was stuck because of the gunk in it. I was planning to put a catch can in it. But I sold it. Also the smaller engine version the IS250 (2.5 v6) really needed a catch can due to carbon build up. So it also depends on the engine I think even if it has a smaller displacement.

This makes sense. Take the 2.4L Jeep engine that produces 180hp...that’s 75hp per Liter. My 07 Yukon with 6.2L 380 hp engine has only 61.3 hp per Liter. Perhaps I will install one in the Jeep just to be safe.

WTF does that have to do with carbon build up and PVC systems?

HP per liter, lol

The components of the systems, if not metal, are actually a form of nylon. Not PVC.

Lol, you know I meant PCV (Positive Crankcase Ventilation). That's what I get for replying from my smart phone little keyboard with auto-correct....not so smart

The setup I have on my Vortech supercharged 5.0 mustang is as follows

PCV port on intake manifold is plugged. No crankcase air gets into the intake track at all.
Mechanical vacuum pump driven by engine pulley. The suction side of this pump is attached to the front of a valve cover with a baffle. The outlet side is attached to a vented and baffled catch can. On the back of the lower manifold where the PCV valve would go, I have an adjustable air bypass valve set to give a constant 13-15" of vacuum in the crankcase. I also have a vacuum gauge mounted inside vehicle that shows crankcase vacuum at all times, which is tapped into a valve cover.

I know they make replacement oil fill tubes/caps that incorporate connections for a vacuum pump and also have an air bypass valve built in, but they're pricey...lol

I know you meant that. I'm just bored. Worked late in the shop last night and too sore to get involved in anything today.

Not sure...still trying to wrap my pea sized brain around all of this. It’s not going so well though. Haha!
