Need input on PCV delete system... I'm experiencing lots of smoke during hard acceleration 
and small amounts of smoke during idling. 
I have all bolt-ons, full exhaust, MS4 
cam swap with the 'all goody' package. The cam swap has only 5k miles so I don't think the valve stem seals are gone yet, but concidering the possibility.
Any input or suggestions would be greatly appreciated.
Thanks.

Sounds like we have the same problem with a very similar setup.....
I highly doubt it's the seals, the shop that did my cam swap told me it was dumping smoke on the dyno. They suggested I may have a bad compression ring.....I'm not to sure if I buy into that or not. The engine is not fresh with 85k miles, but I would hope the rings lasted longer than that. I have never ran nitrous through it,messed with the rev limiter, or overrevved by putting it in the wrong gear since I have had the car the last 25k miles. But besides that point, I have a new set of heads I need to install, and have considered foing the ls6 pcv conversion. The only think I don't like about it is "some grinding to the block may be required..."

Okay, so you're telling me that I need to do the PCV delete system and if so, what parts do I need? Or do I just need to try a search?
Thanks for all the help.. I really appreciate it.

Breathers will vent the fumes into the engine compartment which could give you an odor in the car. In addition they can be a little messy if not seperating oil and fumes. The catch can with the restricted line is suppose to eliminate the fumes. Breathers are a lot cheaper. The catch can with the breather seems to be a good design, dont have my car running right now I'm iun the middle of a h/c swap.
