What is every one doing with your PVC or the two vent lines on the valve covers? I dont want to suck out the oil from the motor. should i be concerned? Thanks

Both of mine go to a duel port catch can which vents to atmosphere through a 1 1/2 filter on the top and drains back to the oil pan. The only drawback to the drain is there is no way to kow if there was ever any oil in there.

Why did you not just run back to the stock location?

If your refering to the line going to the intake, you do NOT want to do that.
Just like in another thread where the guy had oil in his intake manifold, which may have caused his engine failure.
Vent it, if you have a seperate bottle like above then either run it to the pan or just have a valve at the bottom with a hose, each time you check your oil just drain the catch tank. If you have 3.0l valve covers, additional mods will help retain some oil.
Under hard use you will get some oil in the tank. not a big deal as long as your venting it and watching your oil level.
3.2 valve covers or modified 3l help also.

Hot , oily , low oxygen crank vapors are less desireable than fresh compressed aftercooled air!! :biggrin:

Thank you. I will make the change now i only have a few hours on it like stock setup.

I have tiny k&n filters on the end of them, vented to atmosphere rite now. I need to setup a catch can in the very near future, probably after i install the oil cooler. I'm not going to run a drain line back to the oil pan.
