Ls engine issue?

[LouNY]

Based on diagnosis dealer gave me I'm guessing turbo contaminated dpf causing regen cycle to clear dpf. Surmising regen was result of turbo failure not the cause. New dpf due in this week so hopefully I'll have tractor back by weekend. Still very concerned about an engine with 5.3 qt oil capacity with filter being 4 quarts liw on oil in 15 minutes����

I'm wouldn't be surprised a bit, high oil pressure pushed a turbo seal out and pumped oil either thru the engine or directly into the exhaust plugging up the dpf and starting a regen because of the differential pressure in the plugging up dpf.

Bulletin specifies using LS EST to program to latest software level so I assume LS dealer would have access to the update as well.

Thanks for filling us all in. Are you able to post the contents of the bulletin here? I tried searching for it but couldn't find anything......

So, what did they say about that?

Still surprises me that 5w is not thin enough so they have to go to 0w and adjust the software to compensate. That's living on the edge (design) if you ask me.

Not sure if service bulletin is meant to be publicly circulated. I'll check when I get the tractor back and if it's okay with dealer I'll post it here. Pretty much just says exactly what I alerted everyone to regarding dates. Dealer cut oil filter open and normal break-in material inside filter characteristic for 26 hours. Oil sample submitted for analysis and results not back yet. I'm sure this event has worn my engine prematurely and plan to change oil again after 20-30 hours and have a second oil analysis performed for my peace of mind. Other than that I'm not sure what other options I have but cross my fingers and hope for the best.

Excellent info.

Thank you!

Thank you Rusty. I printed it off. I will take it to my dealer and see if he (or a technician) can come out to update my ECU.
No issues with my machine yet, but if this update helps, I would rather prevent this issue from ever being an issue. Thank you!

I wonder what the program commands for the initial start up rpm?

Looks like it delays "operator control" of throttle from 3-60 seconds after startup depending upon coolant and outside temp. Interesting to note, a frost plug heater may fool the computer to force the minimum 3 second delay.

So, again, this is an initial start up issue. Good info on diagnosing turbocharger also. I may have to pull the intake to inspect. I've only had one regen over 25 hours thus far (180 hrs on tractor).
