Anyone know where the PCV valve is on 2004 lesabre 3800 II? can you tell me how to replace the valve? if photos available that would be great...

you may have to take the top plastic cover off to see the valve covers. it will either be toward the top back, or top front of the engine. it will have a rubber vacuum hose attached to it, and you should be able to just pull it out of the valve cover.

this is what it should look like: http://www.partsamerica.com/ProductDetail.aspx?mfrcode=PUR&mfrpartnumber=PV892&parttype=5&ptset=A

pop the hood, remove the engine cover, on the left side of the engine just in front of the alt. you'll see an elec. plug. remove the pug and turn the remaining plastic counter clockwise, once removed you should see you PCV remove it with a pair of neddle nose pliers, swap the Oring from the old to the new and re-assemble
