LS2 block question
LS2 block question I have a 402 ls2 aluminum block from SLP in my car and I have one thing to finish before tuning it. The valley cover has a vent tube or breather tube in the front of it I assume to relieve pressure ? Where does that tube tie into ? Note: I have a 2000 TransAm with all egr etc... stuff hooked up. Should I tee into the line that goes into the throttle body lower tube on the passenger side between pcv valve and T.B. ? or just block tube off ?

Plug a 10in 3/8 line off of it to the port right behind the T.B. on the pass. side of intake "LS6 pcv style". You can also bypass all of it and put a K@N vent where the oil cap is. Goodluck man

No the factory LS1 will use the valve covers. The best way to explain it is that set up sucked to much oil into the intake so we do the LS6 conversion and It sound like the vent on the valley cover is a LS6 cover. Go to www.LS1howto.com and under the F-body section look for LS6 PCV conversion. This should fix you up man if I understand exactly what you are asking.

In all you are going to block of you valve cover holes on the drivers rear and pass. rear valve cover with vaccum block offs and run it from the valley cover 10in 3/8 line to that vent on the intake behind the TB. Trust me you will be glad you did this.
