So Sarge told me to post on up, so here it is. He posted about a how to for removing your PCV and putting in breathers and catch can. But that is for newer ls2, ls1 style motors does/has anybody done this to a 98 ls1? Since the 98 pcv and valley is a bit different in the way it runs, then theirs. Post on up, I really would like to do this just not sure if it would work the same as theirs!!
