Hey guys,<br><br>I have 162,000 mile on my 97 3500. I know that someone used the truck to &quot;hotshot&quot;. (the mileage went up 100,000 miles in two years according to the vin search and regestration data) Anyway, the question is this. I Have run my truck under varying conditions-camper on and off, and I see absolutely no blow-by comming from the draft tube. With that many miles, is that possible? Did someone have this apart? I don't really see any oil useage either. (now that I've sealed up my Vac pump leak Don't get me wrong, I LOVE my CTD! I guess it would be nice to know. Anyway, thanks.<br><br>If this is normal, dang these trucks are tight!<br><br>TJ

 

i had a 97 dually and now have a 97 2500 4x4. they both had blowbye with 40,000 on them

 

97 with 94,000 miles, no blow by, owned it a week so I don't know about oil consumption. Kevin

 

I now have almost 140,000 on my 95 and I don't burn any oil. I also don't have any that comes out of the tube.

 

my 93 has 180k on it and has no blow by. My 94 has a little but that is because of the valves needin checked.<br><br>DM01

 

219,000 on my 94 and no blow by out the tube, nice and dry too. I have allmost 4000 miles since I changed the oil and filter, the oil is still nice and clean. I've never seen anything like it before. All other diesels that I have seen, the oil gets real black and dirty looking fast. This has been on mostly skidders, heavy equipment and bigger trucks. My father in-laws Duramax gets black with in 1000 miles since it was new. We've all heard the stories about the Powerstrokes getting dirty too. Are all these Cummins like this?
