I have a 318 with 152,000 miles on it that uses oil internentintly. I go thrue a qt. every 450miles but never see any blue smoke driveing and it has no leaks.[align=left] [/align]

 

plenum?? maybe.. what do you guys think?

 

Every ONCE and a while when you go to start it it will smoke like a banche for 30 sec.

 

then quite and won't do it agine for a week or two or it my do it the next time it starts.

 

1998 5.9L with 110K, I might go through 1QT in 3500 miles. I normally change my oil at 3000, and when i do its just at or above the min line.
No leaks either, no noticeable smoke, and easy on the skinny pedal on the right.

1 QT in 450 miles is substantial, yes, thats a symptom of the plenum issue. Take off your air cleaner and open the butter flies and look down in to the intake with a flashlight, look back towards the firewall and see if you can see any oil pooled. Grime is normal, but nothing that looks wet or pooled up.

 

Any ideas? I know the intake pan is bad about leaking on these things but this an't a little oil all the time.

 

It don't rattle or knocksome times has a ruff idle when cold for the first min then goes away.

 

with the plentum gaskit leaking should it use oil all the time like bad rings?

 

98Dodge: I have a similar problem on my 5.9 too.

 

I've done the plenum swap but I still go through oil every approx. 1000 miles too
