Help me diagnos black smoke and rising oil level

I'm looking for some help on diagnosing black smoke on hard acceleration as well as a pretty good smoke on soft pedal acceleration. I'm in an 05 Dodge with Smarty Jr. on 3 (80% power) I'm also experiencing a rise in oil level and blowby smell but, no oil from blowby tube. Here's the odd part, Blackstone reports (2 so far) and not indicated any dilution from diesel fuel.

Prior to Blackstone labs, I was leaning towards cracked injector leaking into the crankcase but, the blackstone reports don't indicate fuel in oil. (could they be wrong?)



My diagnosis thus far:

Blackstone labs reports (2) everything looks good, nothing out of the ordinary

Replaced air filter, no visible signs of clogging

Nothing abnormal with EGT etc.

On that setting you are going to get some smoke. Set it back to stock and see if you are still getting excess smoke. A bad injector or 2 is gong to show stock as grey have all the way thru hard acceleration when it should clean up.

Disregard Blackstone if your making oil. . Mostly likely cause injectors, 2nd Pump shaft seals, check daily,if its raising investigate the cause. . Cerb is correct You will have plenty of smoke with that setting.

Okay... backed out Smarty, now on Stock SW. There is some perceivable smoke. It's been so long since being at stock setting that I don't know if the little bit that is coming out is normal. I do have to note that I'm in California and the state is requiring "smog" checks on diesels and it's a completely subjective test that I'm afraid of not passing due to somebody's assessment of acceptable smoke.

How could I disregard Blackstone Labs? Have they had cases of inaccurate test results?

Lockout OD and run the truck as fast as you can at WOT. If everything is working correctly you should not have smoke over 2500 rpms. If you see a grey haze in that rpm range it slikely you have an injector problem. Coupled with the rising oil level I would suspect a problem there somewhere.

The smoke does sound normal for a Smarty, but the rising oil is not.

Are you checking the oil the same each day? Cold to warm makes a big difference on the dipstick, as does vehicle attitude.
