assuming its a 5.3l it should be drivers side valve cover near firewall, but you could also have an orphise tube which doesnt need to be replaced.... just wiped down with a shop rag

this one should also be in the same spot, i havent seen MANY 6.0L but i have seen enough to know that its either in the spot i mentioned in the last post or its a permanent orphise tube. as with the last post it may be a removable orphise tube or PCV / or permanent orphise tube
