what are u guys running for PCV?
Unless it is a racing engine.. I would recommend using some or part of the PCV system to create neg pressure in the engine internal to keep blow by from making a mess excaping and from blowing out the seals. A good PCV system/valve and a Catch Can (optional) should be used IMO.. But thats me.
I have my stop setup on my 99 LS1 engine and using a cheap oil seperator/catch can. On my 02 LS1 engine, I have converted it to the LS6 valley cover. waiting to see if I need a catch can or not.
