I use 1/2qt of 0-30 GC per 2300 miles or so. If I were to switch to the new style PCV with the fixed oriface, would that help? Is 1/2 per 2300 miels bad with GC?

 

new style?you mean ls6 valley cover?because that will slove the problem

 

i just did mine (LS6 Valley Cover),,works great, of course i have only put on about 30 miles since i did it,,but works great! (i was having oil in my valve cover issues)

 

I think what BLKWS.6 is asking about is the revised GM PCV valve that was issued for the trucks I beleive. There is no actual 'valve' inside, just a much smaller orfice than the stock valve.

If so, I tried this in my '00 car, frankly it didn't seem to make any difference. Doing the verticle PCV mod seemed to do more (and even that wasn't a big difference).

My WS6 started using a lot of oil after the cam swap. I think it was a combo of the stock low tension rings with increased cylinder pressure from the cam and the higher stall TC keeping the revs higher with light load on the motor.

 

I have heard it is normal for an LS1 to eat 1/2-1qt of oil per 3000 miles.

 

Switching to GC 0w30 cut mine from 1qt/800mile to maybe half a qt every 8000 mile. I haven't seen the low oil light since switching to GC and have gone through 3 scheduled mileage oil changes.
