BEST way to prevent Oil in intake and puffing out exhasuts at WOT/high rpm what is the best way to have zero oil consumption in you intake/throtle body and from smoking out your exhaust at high rpm/WOT? heres what ive heard of but dont k ow what the key is. (2000 LS1 camaro SS)
- use only a PCV Catch Can? (Norris billet)
- use only a LS6 Valley Cover? (which involves notching the block on pre 02 ls series motors for internal PCV?)
- use both Catch Can and Valley Cover?
- or delete entire PCV system and but a breather filter in where valve cover oil cap is?
whats the BEST?
pics of notching block to fit the ls6 valley are appreciated!
thanks

I have a dual catch can from Saikou Michi and an LS6 valley cover. I still have problems blowing by, not near as much as before, but still a little.
If you want the best way, as your title claims, is to remove any kind of attachment point from the intake. The breather method is dirty and will mist oil in your engine bay under extreme pressure situations. The absolute best method is going to cost upwards of $10K. That involves a dry sump with a small vacuum pump to remove crankcase pressure and oil sloshing. You definitely would not have oil in the intake in this situation, but it's not for the weak hearted and shouldn't be bought just because you don't want oil in the intake. It's more for hardcore racers that have problems with pump cavitation in the turns and those guys looking for every ounce of power.
I would just get a good catch can, LS6 valley cover and make sure you regularly open the throttle. For the exhaust side, the majority of the problem is carbon buildup in the combustion chambers. If you run the engine open relatively often, there won't be enough buildup to actually see.

Not sure if this is accepted but if you want to know about this problem there is a great thread on LS1. The theard is called PCV-Catch Can-Crank Pressure. His setup looks like it works great. Oh and in that thread on the last page they started talking about using an exhaust evac setup to vent the Crank Pressure for like 60 bucks. Hope that helps.
