Likely also passing the rings and making its way into the oil sump. Over time, the veg tends to polymerize into lumpy sludge which will get distributed thru the engine. This lumpy sludge does not lubricate well...
But ring coking itself is bad enough. The most important thing a diesel engine needs is good compression.
