I think there is an updated number..... any vehicle that used the 3.9 will also use the same PCV valve..... So, dodge trucks, dakota/durango, and heaven only knows what else......

 

Exactly. The old part number has been superseded by....

5175352AA

Search on that and i'm sure you'll find it. Get the Mopar part.

 

Looks like rock auto has it...thanks for all the help

 

Take a look under the truck at the oil drain plug area an transmission for a tiny tiny wet point..the 2 piece seal can leak near there too an only as your driving does it leak.But I agree that the plenum can be a factor. How do the plugs look ? I got a OEM PCV at the dealer-they cross referenced to the ram with similar motor .Keep us posted I'm curious where the oil has been going too .

 

Well im waiting for the PCV valve I posted above to come in from Rock Auto. My OEM Hose for the PCV was split a little where it goes into the intake so I put some ultra black permatex on it and let it sit for a day or so. I check it again today and its exactly between full and add so Im guessing a half quart low. I didnt fill it back up this time since its still in the safe area. We have a bunch of snow and ice right now so Im unable to pull the spark plugs out but I didnt see any oil on the oil plug. The condition of the oil is really good, not black at all but sorta like a honey/syrup color and it doesnt look like any antifreeze is in it and the truck runs perfect so Im hoping its the PCV. Right now it has a duralast PCV i put in it back in august but I read its better to use the Mopar PCV so thats what im getting in the mail. Ill kee you updated...thanks for the reply

 

I must've misread your initial post when I said " Losing that much oil, you have to see something somewhere." I was thinking "week" when you said you lost half a quart a month. Not as bad but still not negligible. From my experience, I don't think the PCV valve will have you losing that much oil. I second getting under the truck and checking for leaks.

 

I have had engines leak around the valve covers, and the oil would burn off on the exhaust manifolds..... no smoke, but, losing oil nonetheless.

 

Yep, there are a million ways to lose oil. There's no use in guessing, at least not till you've ruled out the basics.

 

Yes ,or try that additive,you put in the oil, that shows you with a light ,where the oil is leaking from ...
