Need some advise. I took my truck in because of a CEL and the dealer said that the DPF was plugged. I thought all was good until they told me that it would not be covered by warranty beacuse the motor had too much oil in it.

They said that the PCV was plugged and they were not getting poper reading for both Mass air flow and the PCV...I think it was PCV. Anyways all these failures are caused by too much oil according to them.

Does this sound legit to you guys?

Thanks

 

who does your oil changes?

 

I have a company called safe lube do it. Dealer says you need to let it drain for 30mins...I know Safe lube does not... I am working with them to cover the bill but so far they have not stepped up yet.

 

30 minutes??? Seems if you have to wait 30 minutes for it to drain, then you'd have to wait 30 minutes to check it as well. The drain plug and the dipstick are in the same pan, so to get an accurate reading...

I'd look and see if this info is in your owners manual and if not I'd challenge what the dealer is telling you in regards to who is liable.

 

Too much oil plugs the DPF? Two separate issues and a total smoke show by the dealer. I would try a different dealer. The DPF cleaning program removes soot from the DPF and has nothing to do with too much oil in the engine. If the crank case filter was plugged that should have coded too. The oil from the engine would somehow have to pass the rings, not be burned, past the turbo, past the DOC, past the NOX cat and then plug off the DPF? Sure.. The engine would have to consume 1 quart and hour to produce enough ash to plug the DPF and even then it would have to fail cleaning 2-3 times and come up with and EVIC code for a plugged cat, and put you into limp mode.

Tell me again how that is possible. BAFOONS...

 

here is some info for yall

Case Number K44264524
Vehicle Issue Engine oil level is high or may show overfull.;Engine oil may have been recently changed. The customer may state the "Oil Change Required" message comes on too soon / at too short of an interval. Engine oil analysis may show above 5% fuel in oil dilution.
System or Component Oil Level Too High;Customer Concern (No DTCs);Engine Oil
Recommendation * Be aware *. The closed-crankcase ventilation system on the 6.7L Cummins Turbo Diesel engine retains oil much longer than on previous 5.9L engines. Remove the engine oil fill cap while draining the engine oil to allow the CCV filter filter to drain. If the engine is only allowed to drain for a short time, then refilled with engine oil, the crankcase may actually be overfilled. The "Oil Change Required" message displayed on the EVIC is sent over the vehicle BUS system from the ECM. The message is requested when the ECM calculates there is excessive (above 5%) fuel in the engine oil dilution. This calculation is derived from engine idle time and the amount of time the engine is performing an 'active' exhaust regeneration. During these operating conditions, a small amount of fuel will get into the engine oil. This is normal operation of the engine.

Yes, like I said. Maybe Cummins or Chrysler have screwed it up enough now that it DOES retain oil for 30 minutes, but like it states, it will show overfull on the stick. I would think someone might notice this if they were checking their oil regularly. Possibly the tech changing the oil wouldn't, because if the oil is being retained somewhere then it would read 'full' when in fact it was over-full. If that IS the case then I revert back to my original statement that it should state such in the owners manual and if it does not, then Chrysler should assume responsibility for their over-site.

Essentially, you need to check the oil level cold or wait for at least 30 minutes after shut-down. Checking it while fueling up isn't going to work.

 

the only procedure that gives a specific time measurement to wait is checking the oil and that is waiting 15 minutes after shut down to check. no drain time frame given that i can find.

 

Cbrahs is the guy to listen too for many reasons. All the story they gave you doesn't add up and isn't part of the system.

 

I appriciate the reply. I will continue to push back but it does not seem that the dealer is going to give. I cannot duplicate thier statements anywhere and the whole thing seems like bull **** but I need some to find a way to prove them wrong...

 

They need to prove to you the problem! I didn't see if you actually got a service sheet with the DTC codes they pulled on it to determine all of these issues. IF the DPF was plugged off, and they didn't try a stationary DPF cleaning sequence, they need to go back to school..

 

Update: Called another dealership and they stated that my dealership was blowing smoke. Told me to call Chrysler care to help get it resolved. I will have more details tomorrow. So far all signs point to yet another bad dealer experience...

 

....actually they are not totally "blowing smoke". Overfilling the crankcase can cause the oil level to rise far enough to allow it to come in contact with the crankshaft which in turn will coat the cylinder walls with excessive oil that the rings cannot control and will result in the problem you mentioned.... I prefer to have the oil level around the "SA" on the "SAFE" mark on the dipstick after performing a LOF on a 6.7. .....and if it were mine wouldn't go over the MAX mark ever.

Perhaps Cbrahs can pull up that case also....

 

They said the extra oil caused the CCV to get clogged and that whats lead to DPF failure. They have stated that my DPF has not turned on for 3716 seconds.. I have no black in the tail pipe so you would think that they would at least try to get the vehicle to regen and see if they can clean it out. But then again I am not the mechanic... I am taking it to a different dealer tomorrow as suggested by Chrysler Care.

 

That's 62 minutes. Somethings seems off.
