2012 VNL670 keeps doing parked regens

Isn't a good idea to idle the newer trucks...Idling causes def filter to clog quicker....the more times a truck regens while parked the harder it is on the engine due to the extreme high temps during parked regen

 

Have you checked the 7th injector? Has it been replaced? Any codes coming up?

 

Yes, and not only the emission, back in July, my bull gear got damaged while sleeping parked idling . I was in hot Texas , without any APU or other AC options on the truck, the noise woke me up. I end up spending 30k $ on reman motor; It's been defective by design, but i believe the lower oil pressure at low RPM had something to do with it. PTO sets rpm to around 700rpm, and oil pressure doesn't go above 40-45psi at this rpm, perhaps didn't grease the gears properly.
I have Webasto for heating, it's quite affordable , around 1500 $ installed , have to save for some some sort battery powered AC and minimize idling.

 

How did the bull gear get damaged by idling?

 

Well, i was at 1,1 million miles, but the motor was running great, 8-9 mpg, never added oil.
I dont know, i was driving on I-30 W in Texas all good running shooth, was late night got tired pulled over on the ramp at exit 178 to take a nap , idling for AC. After 2-3 hour i woke up by a loud banging, scratching noise coming from motor, right under the dash. I understand the idler gear gets lose from shaft and starts chewing the block or rear timing gears cover contaminating the oil and entire motor with metal shavings, interesting it didnt happen while driving.

 

Well that's what I was alluding to, the idling in itself wouldn't cause the bull gear failure as much as the million miles.
