Change the valve if you never have, along with the two vent hoses and the drain hose that goes down to the oil dipstick tube.

Then change your leaking gaskets caused by this failure-which can also blow you OFHG, and/or oil pan gasket. The weakest link - usually VCG- is going to blow when CVV is inop.
Can anyone point me in the direction of a DIY for this fix. I think I will replace the above Before I get into my valve cover leak, But I dont have a clue what these parts look like, or where there located, or anything like that.....
Any help would be appreciated!
