Yes, and wonder out loud what the 'spot' temperature is at the cam/follower
surface?

Betcha it is way up there...

All that is missing are trace amounts of sulfur, along with free O2's. The
PSI's & temps can make some very nasty acids...

All being churned by the cam and follower and another betcha that there is
electrical current running amok between parts inside the cavity

Take a refresher course on how biodiesel is chemically made... methoxide, sodium or potassium hydroxide in the form of lye and methanol being blended, to strp the glycerine backbone/fatty acids off the vegetable oil, to be replaced with methanol alcohol. What acts as the catalyst for this chemical reaction? What would be the residuals left in biodiesel? What happens when you wash the fuel with water to remove the excess residual methanol? What happens when the fuel is improperly dried completely, which takes a lot of heating to drive the moisture out, making it cost ineffective? :S Is not methanol a free source of oxygen in your fuel? What about residual catalyst left in your biodiesel... what kind of catalyst is it inside your high pressure fuel pump for other undesireable chemical reactions taking place? I am asking, I don't know the answers, nor am I implying that there is a good answer.

Ditto and more rhetorical than anything else...won't crack the books
just yet, but very interested in this topic. As with you, do know
that they created a witch's brew scenario with that pump cam cavity
and choice of lube

Yet another: "goes back to using diesel as a lube such a poor choice"
and "that cam cavity is too small and the flow of lube is not good" and
"in trying to make the form factor small, they have limited their
options"

Back to the current OP's problems...I'd consider a wonderful opportunity
if I was in the OEM engineering group. I'd 'buy' that vehicle, not
let the dealer touch it and bring my team out there to tear it down
to the last nut and bolt, all the while checking everything during
the dis-assembly.

Dis-assembly only after running tons of diagnostics on it first.
