Cascadia burning excessive coolant. HELP!

Take it to the dealer, It will not get better, and if they prove you waited and it grenades you could be held responcible.
Just a thought!

 

Classic DPF/EGR Issues. You have white smoke coming out the exhaust as well. Get it to a Dealer or cummins shop and be prepared to spend a few days getting it fixed, and It probably will go bad again in less then 100,000 miles. All the antifreeze is coming out the exhaust stack. I stopped putting antifreeze and started using water until I was able to get it to a shop to save a few bucks. .

 

I hear Cummins has a problem with the EGR Cooler leaking. Coolant leaks into egr system and thereby into combustion chamber(s).Occasional white smoke from stacks if it gets a good burst but otherwise hard to pin down.

 

This was a constant problem at gordon. Egr most of the time but I did have a blown head gasket once.

Thats why they changed to detroits.

 

know a 2013 that just got a new head gasket.

 

Yep, first thought was EGR cooler. Extremely rare it would be head gasket. And unless there is evidence of coolant leaking around a connection or on the ground, EGR cooler is the primary target, then a head gasket. The first is easier to check. It can happen, though not very frequent, the ISX VG turbo could be eating the coolant. They are water cooled.

 

longer you wait to solve problem the more likely it is to have engine damage or dpf problems

 

I would lean towards the EGR cooler, they tend to leak into the exhaust side and over to the intake (Exhaust Gas Recirculation). Remove the crossover hot pipe and run the engine at idle or high RPM's. If you see coolant or a diesel like substance the there is water present. The coolant and soot mixed look like diesel but without the smell.

 

Fully expect the DPF to need replacing soon after you get the EGR cooler fixed! The coolant messes up the DPF .
