Just seeing if I will have any o2 sensor problems. Ive deleted the pcv system on my track cars. Now seeing if I can go about doing it on my lt1. While doing my cam swap and looking into my 50k intake manifold it was filled with junk... And my only assumtion led me to believe it was the pcv system. I figured why not just delete it all together and run a crankcase evac system via the headers which will produce 5" of vac thru the crankcase. Only worry is will i fry out the 02 sensors... I have to install tubes into the collectors which is right underneath the o2 sensors. Im using pacesetter mid length headers also.... I dont think it would be doing harm because its under the o2 sensor but i maybe wrong, this also maybe advance tech, but i figured i'd post here first see what you guys think.

 

as long as its after the o2s you should be fine

 

That's what I thought also, just wasn't 100% on it.
