350 vortec engine location of pcv val
All I am finding for the Avalance is a 4.8,188.8.131.52 no 5.7 (which is 350cid)In any case the PCV vavle is inside the PCV tube that fits into what appears to be the right rocker cover. What year Avalance are we talking about? would you be amazed if it turns out you do not have a 5.7 engine?
I sold these; they were introduced well after the 350 had stopped being used in trucks and SUVs. Most likely it has the 5.3
