You guys do realize that in some small sort of way your actually harming performance by not running a positive crankcase system??
The problem here and is something we've proven on the dyno and on track experience is that the vacuum created by the air being pulled out of the crankcase is benefical. It helps the rings seal better and can definately make a difference in a high HP engine. Now i realize everyone here isn't going for more power so it will work for what they want *removing oil residue from the intake*. But for those of you looking for all you can mustard out of your truck i'd rethink your process. The ultimate way of creating a crankcase vacuum would be to run a electric or belt drive vacuum pump, we've run a setup in place of a stock SBC distributor for years and have noted an average of 3-5hp gains over running a purely open breather system. The best way for a daily driver to achieve a lower oil consumption rate balanced with a clean intake and even a small gain in power would be to run a much better PCV system. Such as using a charcoal canister in line from the breathers to the intake, just to help remove the oil from the air.

if your turbocharged try and run the catch can from both valve covers to the one catch can then run the intake side of the catch can to the intake side of the turbo. useing a piece of hard tubing like1/2" make a slash cut in the tubing and insert this before the intake on the turbo pointing the slash toward the turbo. when the turbo sucks in hard at boost the air passing past the slash cut tube will create a vacuum which will give you a vacuum in the crank case. make since?

We ran a catch can with a steel wool element in the can, but instead of venting the can into the atomosphere we ran a line to a vacuum pump. This pump which happened to be in place of where our distributor would have been on our SBC created a crankcase vacuum at any RPM and was then vented to the atomsphere. So the pump basically took place of using the engines natural vacuum, using a ton of steel wool and a decent sized catch can we never saw any amount of oil being released into the atmosphere on the outlet side of the vac. pump. This was all on NA engines as thats all we could run in our class. This did show very much promise though with our engine and greatly helped any blow by we were getting before hand.
