Another possibility the CP3 Shaft seals , the weep hole is to allow fuel to leak out threw this hole and the front casting has a channel to allow the fuel to leak out between the cover and the CP3 manifold. If your dipstick shows your making oil this is most likely the culprit , the weep hole or the channel gets plugged over time and the fuel go's right into the crank case. Most CP3 shaft seals start to leak at around 250-300K miles.

When they completely fail you can blow oil an fuel out the breather by the gallon, Check Google out for oil all over truck / trailer, Owners have drained 5 gallons of oil/fuel out.

If this happen to bluetec motors you will be putting oil into the intake... Not good....

I guess bluetec motors have more of a tendency to "run away" then As in a run-away diesel truck?????? Where the crankcase oil is being ingested into the intake and there is no ability to control this rogue fuel (crankcase oil) becoming fuel and running the engine up to and past redline.

I doubt my hole is clogged. I only have 48k on the truck. I have used redline oil which has some of the highest cleaning qualities and Kendall super D which has some of the best soot management properties. The hole would be more likely to become plugged if you use an oil with substandard additives. I am only seeing a bit of (possible) fuel dilution when driving short trips (20-40 miles). No fuel dilution when running 300+ miles per day. Might be I'm shutting down in the middle of a regen on occasion and the oil is hot. But not staying hot enough to evaporate fuel and not being mixed enough to cause the fuel to escape through evaporation.

I will send out the UOA after the holiday weekend. No mail on the weekend is causing the delay.
 
Might.be something about the suction of oil out of the full flow filter (when I change it... It's only half full) that (might) happen(s) not as much (to a lesser extent) for the clean oil right after changing it, but does happen with the oil that has been run awhile.

Could there be something with a partially clogged (Donaldson/Fleetguard) full flow filter that would change that back pressure suction that causes the suction (of oil) back toward the oil pump in a partially clogged filter that might have different pressure gradient in a clean filter that doesn't suck oil out of the filter? I haven't removed a clean filter because I don't have a good enough reason to.

Pretty certain my truck doesn't use or leak a drop of oil anywhere. But when a truck creates soot and does regens which has a potential to drop fuel in oil, volume of oil could potentially increase. It does seem to do that in mine if I drive 20-40 miles at a time (short trips) for several weeks. If I drive 300-400 miles daily (for several days), I see no increase in oil level.

I will share my oil analysis results when they arrive. I am not aware if any of the diesel I've used has been mixed with biodiesel on this 3600 mile usage oil currently in the sump. But I bought fuel in Florida, Georgia, North & South Carolina, and not sure what the laws (and procedures) are about fuel pump labeling in all states.

I've only noticed a slight growth of oil on the dipstick after our June 2018 trip. Have probably only 1000 miles of local driving (staying mostly in one county) that shows I have a little more oil (growth) on the dipstick. Seems local driving (several cold starts) would cause both more soot and potentially more fuel dilution. If my truck was using a biodiesel blend, I think fuel dilution would be more likely. Don't know if the OAI oil analysis will catch biodiesel fuel dilution, or if there is any discernable petro diesel dilution. The UOA will hopefully answer that concern.

I forgot to mention. My bypass filter is always completely full when I change it. Only the full flow filter is about 1/3 full that means that up to 2/3 of the oil is somehow syphoned out of the oil pan when it shuts down and cools off. Would be interesting to know if the partial soot and particle load in the full flow filter is causing the oil level to appear higher than it is by pulling oil out of the filter and draining to the sump?
 
The weep hole corrodes shut the CP3 manifold is Alum and the front cover is cast steel.

Its not likely its your problem Newsa their are limited ways of fuel reaching the crank case, Injectors, Seals or cracked return valley ( extremely rare). Its possible for the head casket to leak into the crank case, but its much easier for the oil to leak externally form the return ports, visually seen.

I'm suspecting regens because it happens not when traveling long-distance. Only when repeated relatively short trips.

No oil level increase on a 2500 mile trip driving 300-400 miles per day. Very slight increase in oil level during 1000 miles of shorter drives.

Unless the suction is pulling oil out of the filter after it us partly clogged?

I'm suspecting 1-2% fuel dilution at this point. And if it is below 2%, I will use the oil another month and test again with a UOA.

oil level increase
If you're checking the dipstick is that accurate enough to determine a rise in oil level? Unless theres a significant increase (or decrease) in a short period of time how could you even tell? Just checking in the morning vs evening would likely show a difference on the stick. The longer the interval between shutting the engine off and checking the oil, the higher the level will appear. It's anecdotal at best.

Agreed. But on previous oil intervals, I have seen it get to the top of the plastic. In 3000-5000 miles.

That is why I will do up to 2 UOA's on this current oil.

I am sending one in this Tuesday and will do another in a month or 1000 miles.... which ever ends on a weekend.

This UOA is my first ever. And these 2 UOA's will determine how long I use the oil.

Currently running 3 gals of Kendall Super D which is a good oil, but doesn't come out of the bottle with as much TBA as Valvoline, Redline, Amsoil, Mobile Delvac, or Delo. (At least I am under the impression it might not).
So not just fuel % will determine when I change it, also the other properties listed on the analysis will contribute to my decision.

My dipstick has been surprisingly consistent parking in my level driveway and after it cools. Except when the oil starts creeping up. I can almost tell when it has done a regen (or partial regen).by small jumps on the dipstick.
 
On my 2011 HO and current 15 my Blackstone reports all came back "less than" .05% fuel dilution. My 98 12V all said 0%.

I assume the less than .05% could mean anything between that and 0.001%.

Is your 2011 deleted?

Does Blackstone ever say that viscosity has degraded? (Either truck)

I'm surprised you don't buy your kits from amsoil. Aren't they cheaper with the preferred customer program?
 
There is phenomenal information here. Thank you for giving me some things to look at.

If I do come to a conclusion it’s an injector. What replacements are recommended?
 
I’m not jumping to that conclusion yet. I was just curious. Nothing jumps out at me as to what the issue could be besides my last oil sample would have had tons of cold weather and idling on it.

The truck doesn’t lack any power and hauls easily.

NO it was not. Just towed with it 1/2 the miles and ran it normally the other 1/2.

Blackstone does show viscosity. I did NOT like AMZ/OIL's reports. I did the tour at Blackstone a couple years ago, they are GREAT people.

Edit: Kendall Super D XA doesn't come out of the bottle with as much TBN......
