2010 Cascadia DD13 EPA07 FAILURES

Hello All.

In our fleet we have about (20) 2010 Freightliner Cascadias with the DD13 EPA07. All are around that 500k mark. This year alone we have had 2 engines fail, with possibly a third today (waiting to hear from the dealer where that truck shut down).

Truck 1 had a catastrophic failure. VERY low engine oil codes (truck was running ok). Had just gotten oil sump seal replaced. Dealership deamed that failure was from the "very low oil pressure and wear on the main bearings". It sent the connecting rod out of the side of the block.

Truck 2. Driver called concerned about the knocking. Dealership said that it needed new injectors. Replaced injectors and then found that a main bearing was spun along with a rod bearing - due to hydrostatic lock from injector overload. Truck had just gotten back for low oil pressure o-ring update. (New o-rings in oil pick up tubes)

Truck 3 ..... waiting to hear details yet. Came back from the dealership last week for same as above o-ring update.

We have been told that this is not common, but have now had 2/3 engines fail in last 4 months. Any one else seen or heard of this?

 

We are on a 40k change. Which is recommended by Detroit. The oil we use is also on their approved use list. Samples are coming back in good condition.

The results of Truck #3 came back with 1-5 main bearing spun. That engine was replaced back in Aug 2013. Injectors are ok. No low oil pressure codes. They have yet to determine what caused the failure.

 

Thanks. Beyond the oil changing.....

We just had the bearings checked 2 weeks ago (was getting other work done). The mechanics at the dealership said that those bearings were in good shape. What would cause them to spin when we aren't looking at what they consider a catastrophic failure? We are little stumped at this point. So is Detroit and Freightliner. Sounds like we will be sending the engine out for a postmortem.

Forgot to mention that this engine is a warranty long block with about 145k on it. It had a warrantable failure in 2013.

 

Detroit set out the service bulletin for the update o-rings in the oil sump pick up tubes. We updated all of these trucks EXCEPT Truck #1 because that update came out shortly after the failure. All 3 trucks have had to get new/remaned engines. They are all being deemed as junk.

Just asked my mechanics. They do seperate the fuel and oil filters - as you described. All the oil changes were more than 3 months. These trucks are all pretty local.
