ddevore Posted October 8, 2014 Report Share Posted October 8, 2014 I have a 2002 Cadillac Deville DHS with 145,000 miles and it burns oil....a LOT of oil. I carry around a gallon of oil with me so I can fill it up every 2-3 times I fill up with gas (1 quart about every 600-800 miles). I was talking to someone about it and they said that the PCV valve is bad and I should replace it. So I bought a new one and removed the old one but, the new one is much bigger than the old one and I can't find one that is the right size. Figuring that since mine doesn't rattle and you can see straight through it that it must be bad and I really need to replace it. I searched for the right part but I can't find it then I read somewhere that the PCV valve is a always open design and it shouldn't rattle. What I would like to know is: 1. Do I need to replace this PCV valve? 2. If I do then how do I find the right part? 3. Will this fix the oil consumption problem? 4. Is it even worth keeping this thing? I keep thinking that it is expensive to fix and would be cheaper to replace it but a monthly payment is hard to swallow. Any help would be nice.
