No problem bud. I'm experiencing the same oil guzzling with mine right now. Plenum fixed(and not leaking, just checked on Saturday), compression is fine, no leaks underneath and a Mopar PCV . I'm beginning to think this is just the way it is with a Magnum. As long as it runs as good as it does, I'll just keep putting a quart in every 3 weeks.

 

PCV valve's a goner.

 

I have 197,000 miles on my truck in 3000 miles its still not a quart low.
Just FYI.

Well mine only has 90K on it. So I don't get it. Everything checks out. But obviously some thing is wrong.

 

mine has 149,xxx on it and consumes maybe half a quart in 3,000 miles if that... Its tough to judge because I only put about 3,000 miles a year on it...
When I bought it the oil looked terrible (black sludge)... I used the risoline brand compression restorer stuff in it and it didnt lose a drop in the 2,500 miles or so I ran it before the next oil change... (I cant remember if I added the risoline to the old oil and ran it right before the oil change or after.... )
Anyway all the doom and gloom stories I have been reading about that stuff as well as engine restore has made me refrain from using it again... especially now that I may have head issues and have to tear into it...

 

Good call using Rislone. You can't go wrong there. Here is pic when I had to replace my oil pan, I didn't take pics when I did the plenum, But the second pic is from my 98. And the 2000 was even cleaner, so I know that it was maintained well.

 

I just changed it Saturday so I'm not sure if I'm still loosing oil. What has me concerned now is the misfire on cyl 5 that won't go awayWell I think that next tuesday I'm going to take it too the stealership and have them see if they can tell me whats going on (compression test) I put a mopar pcv in it tonight and changed the oil put a new plug in cyl 5 so we'll just have to wait and see...Thanks for all the help guys!

 

Please report back when you find something out!

 

yeah I most definitely will keep this thread updated

 

Your plenum is blown, end of story.

Nah, just kidding. Couldn't resist.

Mine has 180k and burns about a quart and a half or a little less in 3k miles. Seems a little excessive, but plenum is fixed and I never see any smoke. Rear main seeps enough to be wet with oil behind oil pan, but not enough to drip. I'll fix that once it starts dripping.
