here is the pcv valve
it is located on the back side of the valve cover driver side it has 3 hoses connected to it. the 2 small hoses are coolant lines, so change it when cold, I did it hot and found out the hard way. they are held on with squeeze clamps, then the large hose just pulls off, remove it first so you can unscrew the pcv valve about a 1/4 turn then you can route it out and up to remove the coolant lines
I also changed the fuel filter, you will need the date of mfgr cause after 5/01 it uses a different filter mine was made 12/00 so it took this filter
