Venturi vacuum pump

What is the white thing on the valve cover line, a catch can?

Its not the size that counts! its how you use it!

I am using this catchcan because you can see through it, if (when) oil starts building up in it, I will know.

A more permanent solution is going to be putting a larger catch can there. This will require moving the location of the catch can, but it will be in the same location in relation to the routing of the vacuum line

umm... i basically just use a tube that goes all the way to the bottom of the engine.... never really had any problems. even boosting 30 psi.

Krank Vents would solve everyone's problem.

Go to the "misc" section and they should be at the top of the page. I ran these on my S2k and they do what they claim to do. They are huge in the S2k community for N/A and boosted guys. On N/A S2k's they generally show a 3whp gain and on a turbo S2k they have shown up to 20 whp. They also eliminate oil consumption; I went from using a quart every 2k miles (normal for the F20C engine) to using ZERO in my 5k oil change intervals.

Did you put a Vac gauge on the crank case to show a difference?

Who are you asking?

I have not measured how much vacuum the thing creates, ill do it because I am curious.

That "Krank vent" is just an upgraded PCV valve. It does not deal with added pressure in the crank case, just look at the picture! and its $110 plus shipping!

Does it not connect to the same place as yours?

The KV's create a vacuum in the crankcase (even at idle). Does the air "woosh" into the crankcase when you pop your dipstick? It does with the KV's. The KV's are one-way valves similar to a PCV, but unlike factory PCV's they do not leak boost into the crankcase. You put one between the intake manifold and the factory PCV and one on the valve cover breather allowing air to only escape but never enter. Doing this increases engine efficiency by reducing drag on the crank/pistons (more power, better MPG) and also helps the piston rings seal better reducing oil consumption. These will also fix symptoms such as leaking gaskets and dipstick pop-out similar to your pump.

You and Iceminion, It would be nice to know the before and after with both setups.

I do not know how much exact vacuum is made, but I will say that at even just idle the oil dipstick is suctioned in and takes some force to pull out, and when it is pulled out you can hear the air rushing in.
