Beyond this is kerosene coking a function of whether or not it is used
as a coolant? Are lox cooled engines which use kerosene fuel also
subject to coking?
Much less so, but it's not entirely out of the question. Coking is
traditionally a cooling-passage issue, but heat soakback after shutdown,
solar heating during orbital operations, or reentry heat could possibly
cause injector coking if the fuel has nonvolatile components that can
linger there. With kerosene, I'd guess the probability is not high, but
not zero either.
