Thread: Hilux EGR

Nope.

It’s the introduction of the EGR heat to modern diesels that is the problem. These were introduced to control NOx emissions. Older diesels didn’t have them, hence no heat and hence no soot.

Yes there’s some soot in the EGR gas, but the combination with the crankcase gases and oil is what causes the modern phenomenon of totally blocked intake systems.

I should do a video of what comes out of my drain line from the oil catch can...
