I have a 2018 Ram with the 6.7 Cummins. At 140k miles I got a code that DPF was at capacity. I contacted a DPF cleaner that told me that he could clean my DPF but he suspects we’ll find coolant in the DPF indicating a problem upstream.
I chose to delete the EGR and DPF. While doing this it was noticed that the coolant reservoir was a little low. I was told that the low coolant was likely due to a failing EGR (also causing the DPF problem). I’ve been worried that it may be a head gasket.
I sent in an oil sample with 7500 miles on it (5500 pre egr delete and 2000 post delete). The oil analysis showed high potassium (130). The lab indicated coolant in the oil.
I replaced the oil with T6. I took a sample at 1200 miles. This time the potassium is at 17 and the lab does not indicated coolant in oil.
Can I conclude that the EGR removal solved my coolant problem? Is 17 potassium too high for only 1200 miles?
