pathfinderproblems Posted November 5, 2022 Share Posted November 5, 2022 Hi all, new member here. Justsaying hi and hopefully find some guidance on changing out a pvc valve. My pathfinder is using oil, going through about a liter of oil every 5 tanks of gas. Hoping it's the pcv valve and nothing else. I understand I need to remove the intake but wondering if I need any special tools or basic tools will get the job done? Thanks for the help.

Jotegir Posted November 8, 2022 Share Posted November 8, 2022 Basic tools will get the job done but it is very, very unlikely to be the PCV valve. The 3.5 is well known for consuming oil and I'm sorry to say I've never heard of a PCV valve replacement solving the issue. Link to comment Share on other sites More sharing options...
pathfinderproblems Posted November 8, 2022 Author Share Posted November 8, 2022 Well that's not what I was hoping to hear. Going to try changing the pvc valve anyway and hopefully change the valve cover gaskets while I'm in there. Link to comment Share on other sites More sharing options...
Jotegir Posted November 8, 2022 Share Posted November 8, 2022 Common places on these are valve cover gaskets and oil coolers for leaks, not to mention RMS. It might just be burning it though, that is very common too. Mine does not leak at all but goes through quite a bit of oil. Link to comment Share on other sites More sharing options...
pathfinderproblems Posted November 8, 2022 Author Share Posted November 8, 2022 OK thanks for the heads up, I can't see any leaks around the oil cooler and the valve covers do look like they are leaking so that could be the issue. Sorry I don't know what the RMS is? Link to comment Share on other sites More sharing options...
