My 2002 24v Cummins has started to leak more oil than it used to and is leaking about a baseball to softball size spot on the ground whenever i park it and let it sit for a couple hours. Can’t tell exactly where it’s leaking from but i see oil beaded up on the bottom of trans, the bolts on oil pan, and on the bolts on the bottom of the turbo if i shine my light up there. Doesn’t appear to be low on oil on the dipstick but the oil was just changed less than 500 miles ago. How much oil do yalls trucks leak and how much is too much to go ahead and get whatever seal is leaking fixed?

 

My 2001 when i had it would leak out about a quarter to a 50 cent piece amount of oil when it was running just sitting in the drive..... mine was coming from the crank case vent. My 2000 hasnt leaked a drop yet

 

My 2000 dripped a bit for a time from what I thought was the main seal. I changed oil to a higher end quality oil (Schaeffer 722 10w-30) and it stopped about 500mi later. It was a gusher when I first got it. Vacuum pump between it and PS pump. Tappet cover. Pan. Front cover, mainly under vacuum pump. Steering box at piman arm leaked too. If you are leaking that much oil, there is a problem somewhere.
