Exhaust evac ttt

Simple and not a hose monster

 

I use a MM Gen 1 PCV Catch Can and it works very well.
Single -12 off the front driver valve cover and then 3/8 hose to the vacuum port on the back of the throttle body.
Keeps my intake clean, moves enough air for 12 psi. and no oil smell.
If your moving a lot of air check out MM 3-port can, do a -10 off each valve cover and the 3/8 vacuum line then you have the best of both worlds.
The other ways mentioned in this post work well too but this option guarantees you no smell and you don't have to wonder if your exhaust will scavenge enough to work.

 

Exhaust scavenging setups are awesome if set up correctly. Its very easy to not produce any vacuum through the system....but that being said, you are currently just using crankcase pressure to push the fumes out, so even if you screw up the exhaust placement, angle, etc, you will just push the fumes into the exhaust rather than out of the filter. Just make sure the hose between the can and exhaust is larger enough that you dont create too large of a restriction which would result in even higher crankcase pressure than you already have.

 

The Moroso pan evac kit works well as long as it’s installed properly.
That means the correct angle and placement of the nipple that goes in the exh pipe.
It needs to pull a vacuum otherwise it’s useless.
Also, you have to place the nipple after any mufflers or it will simply pressurize the catch can or crank case if you connect it straight to the valve cover.
