All good info...The injectors are under the valve cover on a 3126, so the O rings can allow oil into the cylinders. Still wasn't my case, I tried replacing those. It helped, along with a new injector for #6. Didn't fix the problem.Even sent the Turbo back in for inspection (it was just rebuilt by Borg Warner) they found nothing wrong,and rebuilt it again for free. I did have oil in the turbo, but it was just because of the bad oil consumption I was having.
The difference between Bob's and my issue is, mine didn't blow any oil out, only bad blow by. Ours was also using 1 quart of oil every 100 miles or less. In hindsight, it started out using less oil, but started having extreme blow by. I probably drove it too long with the issue it had.I was in denial!
If Bob's turns out to be a broken ring,he may get by with just repairing the one cylinder with a new set of rings.
